Rental Success Story - 6" Traps, Temporary Pipe, Filter Skid, No-Squeal Silencer

TPE delivered to a CAMPOS EPC a variety of equipment to support a 6" inline inspection project including the launcher/receiver, temporary pipe, and a filter unit to prevent debris brought in during pigging from entering downstream piping and equipment. The filter unit was outfitted with a No-Squeal silencer to enable blowdowns to occur without the noise typically associated with high pressure gas release. TPE is proud to work with CAMPOS to support projects that would otherwise require costly and time consuming construction and fabrication, instead temporary equipment can be brought in quickly while saving the customer money at the same time.

Pipeline Launchers & Receivers

In a 2013 article found here, the author notes the four main uses of pigging, and therefore pig launchers and receivers, are:

  1. Batching/Separation
  2. Cleaning/Maintenance
  3. Inspection (ILI)
  4. Position & Monitoring (Mapping)

While our rental pig launchers & receivers can certainly be used for all of these purposes, there are several other reasons an operator may need to call upon temporary pigging equipment:

  1. NGL recovery from gas lines
  2. Commissioning/De-commissioning
  3. Hydrotesting (filling or de-water/drying)
  4. Purging
  5. Line Abandonment
  6. Smart Plug Isolation
  7. Water removal
  8. Process-in-Pipe(R) removal of pipeline debris

Rental Success Story - 30" 600# Temporary Mainline Ball Valves

TPE Midstream supplied (2) 30" 600# rental ball valves to NSPEC Pipeline Services. The instant availability of these large mainline ball valves allow operators and contractors to proceed with projects more quickly than if they had to wait for the typical 3-6 month lead time for these valves. NSPEC delivers pipeline services across North America and with the support of TPE Midstream equipment, can bring minimize downtime and maximize project ROI for the pipeline operator.

Rental Success Story - TPE + TDW + TransCanada 10" 600# temporary launcher and receiver

TransCanada contracted with TDW to provide TPE Midstream launchers and receivers for a recent 10" 600# pipeline project in Canada. TransCanada maintains a strict protocol for ensuring that all temporary equipment is up to their stringent permanent equipment standards. TPE Midstream rental traps are built above and beyond these standards, and have the MTRs, hydrotests, and records databooks to back up the quality. It was this quality equipment, and the service provided by TDW that made a successful pipeline inspection project possible. We will look forward to this Operator + Contractor + TPE Midstream rental equipment partnership to continue to deliver value to the field and support 1st run success with inline inspection pigging projects.

Product Spotlight: High Pressure Large Diameter Temporary Pigging Traps

As the only provider of large diameter (36"+) 600# pigging launchers and receivers, TPE Midstream can offer a unique value to operators. During construction or acquisition of a pipeline system, many operators don't realize that there are millions of dollars invested into permanent launcher and receiver stations that are only rarely utilized. Many operators prefer to have an on-demand solution using TPE mobile equipment rather that sunk cost in assets they don't use - but the decision makers don't know that such large, expensive, heavy equipment is available as a rental asset. TPE Midstream has all of the smaller pipe sizes, and now has 24", 30", 36", and 42" 600# equipment as well. If you are involved in the decision making process regarding launcher and receiver equipment on a large diameter pipeline, know that TPE Midstream can help you save millions of dollars in CAPEX through a simple rental agreement with our mobile traps.

Total Emission Control - A matter of time

When looking at methane emissions within the natural gas infrastructure and the regulatory requirements that govern the amount, frequency, and method that natural gas is vented, most of today's laws and incentives are pointed toward very large emission sources. This parallels that approach that diesel engine emission regulations were rolled out. As the various Tiers of diesel regulations were unveiled over time, the amounts of permitted emissions were reduced in each Tier. This progression is generally well known and often discussed among equipment professionals.

A lesser known and much less discussed trend in the progress of these emissions controls is the size of the engine that is required to comply. At first, only the largest and dirtiest engines were affected. Then more common large on-highway engines came under regulatory control. Now, any emission over 25 horsepower is covered by Tier 4 Final. However, anticipated under Tier 5 (Stage 5 in Europe), EVERY DIESEL ENGINE REGARDLESS OF HORSEPOWER will fall under the new requirements.

When we look at natural gas emission regulation for upstream, gathering, transmission, processing, and distribution, we see a similar trend. Most regulatory agencies and companies are focused on the large, but relatively rare, emission events such as whole-line blowdowns. Very few companies are looking at the smaller, but much more common events like launcher and receiver blowdowns that occur multiple times per day at many pigging stations.

We know by looking at the past regulatory path of diesel emissions (and other pollutants like Freon) that while regulations start by addressing the most eye-catching events, the rules eventually reach the smaller everyday actions that are performed by countless O&G professionals every day. Just like diesel emissions rules starting with large equipment and now affecting every air compressor and pump, methane emissions rules that are now looking at the biggest blowdowns will eventually affect every pig trap and filter vessel.

Is your company prepared to perform regular maintenance and operations with Total Emission Control? That is, could you do every part of your job without ever venting methane? With our ZEVAC (Zero Emission Vacuum and Compressor), you can. Just fasten the drawdown hose onto the equipment you need to remove the gas from (connect to the existing "vent" valve) and connect the discharge hose wherever you will compress the gas (a bottle or another portion of your system), and let ZEVAC work. Just like any compressed air tool, it is non-sparking with no electronics to worry about. The ZEVAC enables emissionless pigging, emissionless filter vessels, emissionless separation, emissionless hot-tapping, and loads of other applications that involve venting methane as a standard operating procedure. You can get ahead of the regulations and start operating with Total Emission Control using the ZEVAC today.

Rental as a strategy for adapting to ILI tech changes in the future

Some people ask, "What do you think will change in Inline Inspection Pigging in the next 3, 5, or 10 years?" and I think it is much more reasonable to ask, "What do you think will still be the same?" Inline inspection pigs are incorporating more technologies, incorporating more flexibility to navigate pipeline components, and are being run for more reasons on more different types of pipe than ever before. 10 years from now, I think the industry will be difficult to recognize.

When we discuss rental equipment such as pipeline pigging traps, one of the most common responses is, "We prefer to buy our own permanent equipment." That's a typical approach when evaluated by operations and financial decision makers in the pipeline company. However, if you think about purchasing specialized support equipment (like launchers and receivers) as a commitment to current technology, it becomes very shortsighted to install anything permanently.

  • How many legacy launchers and receivers are out in the field that are not capable of handling ILI tools?
  • How many of those launchers and receiver traps are being replaced now that smart pigs exist?
  • In 10 years, with the next generation of inspection technologies, will we be replacing everything again?
  • OR, will that equipment be necessary at all?

If you consider that renting equipment allows you to be flexible and to change the latest and greatest inspection pigs as they evolve, you are not only keeping up, you're saving the cost of multiple sets of permanent equipment. Permanent equipment that will be is continually being made obsolete as the smart pig evolution continues. Consider rental as not only an operational or financial solution to your equipment needs, but also as a strategy that embraces change.


Coming Soon - An Emissionless Equipment Evolution for Safety and Environmental Controls

Quickly approaching is a day when every gas process vessel will be equipped with the ability to de-pressurize itself without venting gas to the atmosphere. Just as every vessel is required to have a PSV for safety, every vessel will have a Contained Depressurization Device (CDD) that allows the gas in the vessel to be "pumped out" instead of vented. This will change the way facilities are laid out, plant piping is designed, and will ultimately improve the operational safety and the environmental impact of gas process stations. TPE will be publishing application guides that can assist your design team in evaluating the possible uses of our CDD, the ZEVAC (Zero Emission Vacuum and Compressor) to implement emissionless depressurization into your facility and equipment designs.

How can we be local - everywhere?

Equipment rental in the midstream pipeline industry is highly driven by word-of-mouth and more often than not, the local company that has proven itself able to respond and mobilize quickly will win the business. TPE has accumulated the largest rental equipment fleet of high pressure launchers and receivers in the midstream industry, but having the majority of the inventory located in Tulsa, OK has limited our ability to build deep, local roots in the places where business is won and lost faster than we can drive from Tulsa to the jobsite. Places like PIttsburgh, PA, Bakersfield, CA, and Edmonton, Alberta in Canada are places were TPE sends a lot of rental equipment every year. However, we're looking to do more in these places. That's why we're committing to moving our assets closer to the customers. Through a series of "TPE Dealers" that will be announced this year, we will be partnering with local service providers to bring TPE Midstream inventory on the ground closer to the jobsites. For our customers, this means less freight, faster response times, and a deeper working relationship. For our Dealer partners, we're giving them the ability to self-perform work they didn't have the equipment to execute before. Our dealers can also offer TPE equipment alongside their own rental offerings as another value-added service they can provide. TPE is committed to our core values, the 3 C's, and moving our equipment closer to the jobsite drives all 3. Our dealers can provide superior customer service by placing "boots on the ground" to support customers when TPE is farther away. By combining the inventory locations of all of our dealers, we can offer a more inventory than ever before. And last but not least, we can lower the cost of projects to our customers by reducing freight and response time.




1. Customer Service - We are here to help our customers solve problems. TPE aims to be a company that is a pleasure to do business with. We want to be a superhero for our customers, delivering solutions in stride with unmatched responsiveness.

2. Comprehensive Inventory – TPE currently boasts the largest high pressure (600#) fleet of pipeline launchers and receivers in the industry. We are constantly adding to our equipment base, and our aim is to grow into a wider variety of equipment as our customers request it.

3. Capital – TPE is determined to be the low-cost provider in every equipment category we represent. We believe that there are 2 types of companies in the world: the companies looking for ways to charge more, and the companies looking for ways to charge less. We are the latter, and we are constantly driving our costs down for the benefit of our customers. The more we can help our customers save capital, the stronger our customer partnerships will be.

Keeping these 3 “C”s in mind allows us to evaluate the constant flow of data ask ourselves 3 questions whenever we make a decision:
Does this help our customers? – or – Does this make TPE easier to work with?
Does this add to our equipment offering?
Does this help us drive our costs and prices down?

TPE Midstream founder, Doug Sahm, speaks at the Pipeline & Energy Expo

April 3-5, 2017

The Pipeline Energy Expo is a two-and-a-half day conference which will target every aspect of the pipeline industry, including engineering, construction, inspection, supervisory control and data acquisition (SCADA), maintenance, rehabilitation, safety and integrity. The conference will offer prime opportunities for pipeline professionals to learn, network, and seek innovative solutions and products. The exhibit floor at the Pipeline Energy Expo will allow visitors to experience new technologies, view equipment demonstrations, and network with those energy industry leaders.

Doug Sahm, the founder of TPE Midstream, will be speaking on the importance of managing the integrity of temporary equipment. His presentation, An Integrity Management Approach to Temporary Pressurized Equipment Requirements, contrasts the stringent requirements of documentation regarding OQs for personnel and permanent records (MTRs, hydrotests, etc.) with the absence of requirements for temporary equipment.


Debate over Natural Gas Regulation

Methane (the primary constituent of natural gas) is a greenhouse gas as well as the cleanest burning fuel we have. While many energy companies have both oil & gas interests, the two commodities are very different. The debate is continuing to evolve, and is picking up speed as natural gas usage increases. Learn the issues and contribute to the discussion.


New Product Deployment - ZEVAC (Zero Emission Vacuum and Compressor)

The entire world is looking for solutions to the methane emission (methane is a 25x more potent greenhouse gas compared to CO2) problem, and the natural gas industry is leading the way to an emissionless future. At the EPA Methane Challenge Technology Transfer Workshop, TPE Midstream unveiled its new, patented, ZEVAC unit as the premier solution to eliminate methane emissions.


ZEVAC image.png

The ZEVAC is a pneumatic powered vacuum on one side that suctions natural gas (methane) from any pipe or vessel that needs to be de-pressurized. The other side of the ZEVAC unit compresses the gas back up to pipeline pressure so that it can be discharged into nearby transmission, distribution, or process piping.

It has never been this easy to avoid methane emissions. Contact TPE Midstream to sign up for a pilot program today. We'll work with you to deploy the optimum number of units in the best size and configuration so that you can eliminate methane emissions from your system operations.

Success Story: Florida Gas using TPE 24"x36" Traps and Process-in-Pipe Insert

Florida Gas (Energy Transfer + Kinder Morgan) deployed 24" traps and a Process-in-Pipe (PIP)separator to their line for a DOT compliance EMAT inspection.

The Launcher and Receiver were installed, and the PIP Separator was installed in the receiver to prevent liquids from reaching the facility during cleaning pigging operations.

After a progressive pigging strategy was successful, the PIP Separator was removed, and the Inline Inspection pigging was executed. The clean line and ILI capable TPE Launcher/Receiver equipment made for a successful pigging project and on-time 1st run success for the inline inspection.

As new lines get tougher to permit and build, taking care of aging infrastructure will become incredibly important.

As pipeline construction becomes more and more difficult (think Keystone XL, Dakota Access, etc.) - the pipes that are already in the ground become more and more important. Many pipelines are already beyond their originally intended service life, and as energy demand grows, not only are new assets becoming more difficult to construct, the older assets are being pushed to higher throughput capacities. As Richard Kinder elaborates, it's an issue that will shape America's energy future, and it is likely to put the spotlight on caring for the existing pipe.

No-Squeal Silencers deploying on all rental traps in 2017

TPE Midstream will be deploying it's No-Squeal silencers on all 600# rental traps during 2017.  

 Crews deploy signs and notify residents that trap blowdowns will be creating loud noise levels at night in suburban Orlando.

Crews deploy signs and notify residents that trap blowdowns will be creating loud noise levels at night in suburban Orlando.

TPE Midstream rental traps, equipped with the No-Squeal Silencers, provide a safe method of lowering the sound pollution caused by trap blowdowns. Reducing noise levels by 30-50 decibels, many trap blowdowns are below the OSHA hearing protection threshold, so workers can safely communicate on the jobsite, even while the trap is depressurizing.
