Standard Safety and Supply Partners with Gangline™ to Keep Oil and Gas Customers Secure in the Permian and Beyond

Gangline™ temporary iron restraint system enables Standard Safety and Supply to be a full-service oil service provider for its oil and gas industry customers. Standard Safety and Supply, a nationwide oilfield service provider based out of Odessa, Texas, has been impressed by what Gangline™ temporary pipeline restraint system has done for its business.
Trey Moya, one of the four partners in Standard Safety and Supply (Standard Safety), started looking into restraints at his business partner’s behest, saying the partner “came to me with the idea of restraints….[I] started looking for the typical one that people use out here, but when I started doing research I found Gangline™, looked into it, and thought it was pretty neat”.
Reduced Rigging Time
Moya’s search is not unlike the usage situation of many oil and gas industry service providers and operators, who begin looking for restraints to comply with OSHA recommendations, company best practices, or common-sense measures. Often, unless users have heard about Gangline™ or seen it in the field, they are unaware of the savings and peace of mind that they can pass on to their customers by using it.
The decision to greenlight Gangline’s™ new technology on the iron was a great one, Moya says. He said that he was surprised by what Gangline™ was able to do for his customers. “We started using it because a customer requested it initially, then we started using it on the acid side, and then we started using it on flowback. Our customers love it because it cut standby time for customers by half.”
Such results are typical for Gangline™ customers, states Bobby Allen, VP of Trinity Sling, the company that created Gangline™. “We hear these comments over and over again. Standard Safety has been great at getting the product out in front of its energy industry customers, and as I’m sure they would tell you, once the system is rigged up on the temporary pipeline, it sells itself.” Moya agrees that it has been fantastic for business. He notes that “the reduced time and cost is more beneficial for our customers. Everywhere we’ve gone as a third-party supplier bringing it to oil companies and third-party customers they’ve loved it. Soon we hope to be the main provider to everyone out in the Permian area, and they all love Gangline™.”
Water-Resistant Technology for Permian Temporary Pipelines and More
Standard Safety found Trinity Sling’s Gangline™ at the perfect time for the energy industry, both for fracing and pressure pumping operators. Standard Safety provides rig-up and rig-down services for temporary pipelines throughout the Permian, Eagle Ford Shale, and North Dakota [Bakken Shale]. Moya has been happy with the partnership, saying that “my partner Chris [Shields] promotes our services, I come in to supply the technical side and tell [oil companies and service providers] how we can help them, and then Gangline™ completes the circle as a whole, so it works.”
Prospects look great and show no signs of stopping. Since Standard Safety adopted Gangline the install time has been “cut in half”, as Moya puts it. “Normally with the other products [restraint rigging] took forever. Then we found Gangline™ and started rigging up line, and it was water-resistant, rigged up quick, and was new technology, so it just rolled together and worked.”
Expanding Temporary Pipeline Rigging Services with Gangline™
Standard Safety plans to expand its reach in the Permian, looking to bring its service package, of which Gangline™ temporary iron restraint system is a vital part, to more oilfield and fracing industry customers. With Gangline™, Standard Safety and Supply is perfectly situated to pass savings on to new as well as existing customers and help their customers feel secure on the pad. With Gangline™, both Standard Safety and its customers win.
When asked what else Trinity Sling and Gangline™ could do to help Standard Safety help its customers in the Permian and beyond, Moya laughed and said, “Keep pumping out those restraints faster!”

Trinity Sling to feature Popular Gangline™ Temporary Pipeline Restraint System at Global Petroleum Show

Trinity Sling’s Gangline™ temporary pipeline restraint system for pressure pumping and hydraulic fracking will be prominently featured in the company’s exhibit space at the Global Petroleum Show in Calgary, Canada June 13-15, 2017.

The Gangline™ system, a temporary pipeline restraint system patented by Trinity Sling, has been flying out the door at Trinity Sling headquarters. “We have been overwhelmed with demand as oilfield and gas operations have ramped up extremely quickly,” states Bobby Allen, Vice President of Trinity Sling. “We feel really good about our Gangline™ temporary pipeline restraint system, the peace of mind it gives operators on the pad, and what increased job site security precautions do for the industry as a whole.”

A Revolutionary Temporary Pipeline Restraint System

The Gangline™ system, which was created and patented by Trinity Sling in Arlington, Texas, is revolutionary in its design. It is the most lightweight, flexible temporary iron restraint system in the industry. A dedicated restraint system, it offers quick, easy rig-up and rig-down on the pad. It ships worldwide, stores easily and transports well, can be adjusted to accommodate myriad job specs and sizes, and has a clear and traceable serialization and date of manufacture.

The Gangline™ system’s capability also exceeds expectations. Constructed in three rating sizes to accommodate a variety of iron diameters and pressure ratings, the system is certified for a maximum pressure pumping rating of 15,000 psi for 2” and 3” iron, and it is certified for a maximum pressure pumping rating of 10,000 psi for 4” 1502 iron. A third rating size is available for 4” iron up to 15,000 psi, accommodating additional pressure pumping needs.

The system meets or exceeds compliance requirements for new regulations established by the Office of Health and Safety (OHS) in British Columbia and outlined by Worksafe BC. The Office implemented new standards in 2015 governing temporary pipeline restraint that require that, among other things, a temporary pipeline restraint system have certification by a professional engineer as to its adequacy for the purpose for which it is being used. The new standards also require that the temporary pipeline restraint system contain installation instructions, conform to certain engineering specifications as to anchor points and other details, include precautionary information and limitations, and produce testing certifications. Finally, the OHS guidelines require that any temporary pipeline restraint system used in British Columbia be accompanied by instructions on how to use, maintain, inspect, and remove different pipeline components from service. The Gangline™ system meets every one of these standards. Gangline™ systems were designed for exactly this purpose and are in compliance with these new British Columbia OHS regulations.

Compliance-Driven and Designed for Pressure Pumping and Fracking Job Sites

The Gangline™ restraint system is in a class of its own, meeting or exceeding worldwide standards and withstanding extremely strenuous conditions for long periods of time. The high-modulus synthetic fiber is durable and maintains its inherent strength for long periods of time. Gangline™ components thrive in difficult conditions, and the material is intended for gas and liquid in energized and non-energized operations. The Gangline™ components are constructed from material that is:

  • Hydrophobic: Does not absorb oil or water, yet is washable
  • UV-Protected: Stays protected even in direct sunlight
  • Corrosion-Resistant: Remains unaffected by corrosive materials
  • Chemical-Resistant: Stays strong during unexpected leaks and spills
  • Temperature-Resistant: Maintains integrity in sub-zero conditions

Leading the Industry with Professionally-Engineered Innovation

Trinity Sling knows the pad is a site of split second changes, whether they be job-driven, operator-driven, or company-driven. Recently Trinity improved its Regular Duty (RD) Gangline™ offering to include carabiners instead of shackles, giving operators an even more flexible, quick option when working on jobs. The Improved RD Gangline™ system is professionally engineered to offer lighter construction, faster installation, fewer pieces (all-in-one design), and a positive locking connection, the perfect choice for a job that needs to rig up and rig down quickly or requires changes on the fly around mid-line connections. With Gangline™, operators and people on the job site can get the job done faster and easier and with peace of mind.

Trinity realizes that often jobs rig up with short notice and require non-standard numbers of restraints. To serve all job sizes and needs, Trinity offers Gangline™ systems for rental or purchase in custom sizes to suit the job. Sometimes jobs don’t proceed according to plans. Nature and governmental forces can be unpredictable, and Trinity is here to help. Gangline™ temporary iron restraint systems offer corporations and operators security on the pad, and Trinity knows how to make those temporary pipeline restraint systems work to suit the job in the way each pressure pumping or fracking job requires them. Gangline™ is engineered to help get the job done easily and quickly.

Gangline™ Flow Line Restraint System Recertification: Key to Smooth Pressure Pumping and Hydraulic Fracturing Operations

Arlington, Texas – When Trinity Sling customers think of the Gangline™ flow iron restraint system for pressure pumping and hydraulic fracturing, many don’t think about the process that differentiates the system from competitors and ensures that the system restrains the 1502 flow line or other pipe as it was intended: the recertification process.

RecertGanglinePullTest1-LoResification takes place daily at our Arlington, Texas headquarters. The process is a necessary part of Gangline™ system rental or ownership, making sure the pipe restraint system performs to manufacturer specifications. Recertification, a necessary process, is a quick turnaround for customers, for Trinity Sling employees understand that those slings that we receive for recertification are needed for a job to continue. Our employees move the Gangline™ components we receive through the thorough recertification process and out the door as quickly as possible.

What is recertification? Recertification is an annual process in which we at Trinity Sling examine the Gangline™ (or other Trinity Sling-manufactured) components for damage that has occurred since the prior year’s examination/certification. We also test the strength of the sling or other device in a pull test to ensure it still performs to the listed specifications for that device as noted on its tag. In the image above, Carlos Bernal, our Shop Foreman, is recertifying the Gangline™ using InfoChip® technology. New Gangline™ slings are created with an InfoChip®, an RFID chip embedded in the sling to facilitate easy testing and recertification. Listed below is the process that Carlos or other trained employees go through annually either to recertify or initially inspect and certify a Gangline™ sling.

First, we begin the testing and recertification process for a Gangline™ component sent to us by a customer for recertification. We scan the sling with a Bluetooth scanner, and the individual sling’s information pops up on the screen. In this case, the sling Carlos is testing is the yellow 7/8” HD short sling pictured on the testing device.

Once this sling’s information pops up onscreen, our employees edit and verify the information in the InfoChip® system, comparing it to what we see on the sling tag.  We pull test all slings to make sure they pass our manufacturers’ specifications.

Once the sling passes the pull test, then it is sent to our nylon department, where it is retagged with a new recertification tag that lists the current date and expiration one year hence. If it fails, the employee marks that the sling failed the test, the sling is retired from service immediately, and the customer is notified of the failure by one of our sales team.

All slings are tested before they are recertified and shipped. Once testing is complete, we pass/fail the sling, upload the Passing slings’ recertification papers (Certificates of Test) to InfoChip® for each serial number, and ship them back to the customer. Typically, depending on demand, our turnaround time for pull-test and recertification is a couple of days in the shop plus time spent in transit. Our trained employees recertify numerous slings each day.

The testing process is equally rigorous for newly-manufactured Gangline™ system components. Trinity Sling’s Gangline™ department manufactures Gangline™ system components (slings) daily in our facility. We make slings in several sizes, including RD (1/2”), HD (7/8”), and XD (1 1/8”). We also manufacture slings in several lengths: short, long, and extra-long.

All new slings are inspected and certified, receiving certificates of conformity once they complete the certification process. They are shipped according to customer need and are listed in the InfoChip® system by serial number, just as the recertified ones are.

The chains on the floor at the bottom of the picture (above) are customers’ property that has been sent in for recertification, as well.  This recertification process is conducted via InfoChip® Bluetooth scan and verification against existing data, as well.  Each Trinity-tagged, individually-identifiable chain is visually inspected by our employees. The employee notes the length, size, and grade of the chain, comparing the information in the system to what he sees on the chain itself. Chains are brought annually by customers or sooner if there is an immediate failure, a break, or bent hardware. We repair and replace the non-working item(s), pull test each leg to two times the working load limit for that chain, and return the chain to the customer.

Pull test and certification information is always available for new or recertified tagged Gangline™ restraint system slings, chains, or other equipment manufactured by Trinity Sling. Customers can log in on our website to see by serial number the usage location, performance on the test, upcoming due dates for recertification, ownership, and our manufacturer’s information.

We receive slings via freight from Canada, national US customers, and drive-up customers. No order is too small or too large for us to handle. The Gangline™ restraint system is frequently recertified for temporary pipe in fracking or pressure pumping performance. The Gangline™ restraint system helps make sure customers get the job done smoothly and on time.

CTC Contracting Trained on Gangline™ Temporary Pipe Restraint System, Conforms to OSHA Recommendations for Flow Line Restraint

Gangline™ temporary pipe restraint system Installation Specialist Larry Luskey (R) trains CTC Contracting’s Cody Cooper (L) at Trinity Sling Headquarters on Gangline™ installation for well testing in British Columbia, Canada.

On Aug 29, 2016 Trinity Sling welcomed Cody Cooper with CTC Contracting of Cecil Lake, British Columbia, Canada for comprehensive training on Gangline™ temporary pipe restraint system installation.  Training consisted of a classroom tutorial and a hands-on training session simulating a field installation.  The training was custom-tailored to CTC’s area of well testing using 2” 602 flow iron with kelly hoses incorporated in the pipe string. Gangline™ restraints were used to create a 602 pipe restraint system with hose hobbles utilized for added protection on the kelly hoses.

CTC’s recent hands-on expert Gangline™ instruction is just one example of the tailored training available with purchase or rental of a Gangline™ system of pipeline restraint from Trinity Sling. Even during times when wells are not operating at capacity, companies conducting well testing, like Cody’s, benefit from the customized service that Trinity provides, whether at the Arlington, Texas-based headquarters or on the frac pad/in the oilfield.

Trinity’s training is quick and thorough, illustrating exactly how to rig up and rig down the pipe restraints, from 200’ of regular duty 2” 1502 pipe for flow lines in the oilfield to 2000’ (and up) of heavy duty 1502 frac iron for frac line use. Trinity custom-builds solutions to customer specifications. Need a system of 1502 pipe restraints? Trinity has it. Need to secure your flowback iron? Give Trinity a call.

A pipe restraint system for temporary pipelines is not just a good idea, but recommended by OSHA, as well.  Employee safety around the frac lines and flow lines of a temporary pipeline, though always important, is now drawing a more careful look from OSHA. OSHA’s recommendation, detailed in “Hydraulic Fracturing and Flowback Hazards Other than Respirable Silica” describes potential dangers to employees on the frac pad or well site, including employer responsibility to protect them:


The Gangline™ satisfies OSHA’s requirements, and Gangline™ is engineered, tested, and created specifically for temporary pipeline restraint in fracing or oilfield use.  Any time fracing or oilfield operators need restraints for temporary pipelines of all sizes, types and lengths, the Gangline™ pipe restraint system can protect employees against pipeline whipping in the event of a pipeline rupture.

No oilfield operator or fracing operation wants to face a line rupture or equipment failure, but loss of life or debilitating injury incurred in the process tragically compounds the problem and results in loss of people, property, and profits. A smart operator protects all three with the engineered Gangline™ temporary pipeline restraint system. Fracing jobs and flowback operations currently at lower production levels are perfectly situated to train their people on or use our team to install Gangline™, taking those precautions before demand increases and a rupture could occur.

The Gangline™ restrains coil tubing and all other types of temporary pipelines for pressurized iron, both on the frac pad and in the oilfield. To learn more about the Gangline™ temporary pipe restraint system, call Trinity at (855) 471-5482 or

U.S. Oil Primed for Comeback following Brexit Market Reaction

U.S. Oil Primed for Comeback following Brexit Market Reaction. U.S. oilfield and hydraulic fracturing activity has been down, as all market participants are well aware, for some time, but a recent UPI article notes that things may be looking up. The article notes that the Brexit vote on June 23, which determined that Britain will leave the EU, “erase[d] two straight days of heavy losses in crude oil prices”. The article continued to note that investors are seeking secure places to invest after the UK’s credit rating fell.

Such gains, although not necessarily permanent, are great news nonetheless for oilfield and hydraulic fracturing operators in the U.S. Oilfield downtime is the perfect opportunity to take stock of safety measures on the pad, and to protect pipelines company-wide so that when oil or gas production ramps up, oilfield and fracing operators are ready. The patented Gangline™ system is a reliable, easy, professionally-engineered restraint system to ensure pipelines are secure in the event of a pipeline failure.

With Gangline™, oilfield operators will be ready when the market gains referenced below are steady and considerable.

Gangline Website – Launch


Gangline Website

Representatives from Trinity Sling (in blue) and Crown Supply, Inc. on a recent large-scale Gangline™ installation in the Bakken Shale in North Dakota.

Trinity Sling, licensed distributor of the patented Gangline™ Pipe Restraint System, is proud to bring you this innovative, new website for our revolutionary temporary pipeline restraint system that improves oilfield and fracking safety. The new website provides a comprehensive overview of Gangline™ and its many benefits.

Here you will find a wealth of technical information on the product, receive information on training and installation, access documentation of certification and recertification of Gangline™ components, and find many pictures and a video.

See first-hand what happens when a temporary pipeline malfunctions in a pressure failure, and you will understand how dangerous temporary iron can be to crews working on an oil field or fracking pad if these temporary pipelines are not properly restrained with a reliable, high quality pipe restraint system like the proven Gangline™. The video shows how the brilliantly engineered Gangline™ layout creates a choke on either side of a rupture reducing in-line flowline movement as well as lateral (whip) movement.

The new Gangline website will also feature a video demonstrating the ease of installing the Gangline™ system on a temporary pipeline. Easy and quick assembly and disassembly is a well-known trademark of the Gangline™, as touted by Jim Richardson of Mercer Well Service in Texas. “The ease of application and transportation are a big advantage and selling point of Gangline™,” Richardson says.

Besides providing outstanding information on the Gangline™, we have built the new website to enhance customer service. Customers can request service and product / parts information through the site, and a “request a quote” feature makes it fast and easy to get cost estimates in the works for a Gangline™ system.

The Gangline™ has greatly expanded its presence in oil and gas fields around the globe. Demand for the product is increasing, and parent company Trinity Sling is prepared to meet the industry’s needs. Company representatives who work with the Gangline™ System comment:

“We are committed to expanding Gangline™ distribution throughout the fracking and oil field industries. We have been successful in expanding into Canada and other locations worldwide. Although the oil industry is going through a difficult time, we still are confident that we have a lot of opportunity for Gangline™ to make a big difference for oil companies and fracking and oil field operators, as these companies are looking to increase efficiency and safety, which is what Gangline™ helps to do.”

Those same representatives said that last August in Canada, British Columbia passed a new law requiring engineered restraint of pipe systems on oil field and fracking work sites to protect workers. Trinity Sling and its Gangline™ pipe restraint system were quick on the scene in working with oil field and fracking companies to ensure their operations were in total compliance with the new law. This alacrity illustrates Trinity Sling’s service-minded business model, and through their resources and inventories, it also demonstrates their ability to deliver the market’s premier temporary pipe restraining safety solution to operators throughout British Columbia in an expedited manner, the company notes.

Closing Thoughts – Why Gangline?

According to Trinity Sling, “We developed Gangline™ at the request of some of our oil field customers, who had a need for a secure, durable, easy-to-rig and rig-down on the iron, lightweight oilfield restraint system. We created it, engineered it, tested it, patented it, and are selling it domestically and internationally to meet the changing needs of the oilfield. We look forward to getting more of it out on the iron in the coming year as word spreads.”
