PRCI TDC Tours Before PPIM 2024

February marks the third anniversary of commercial Pipe Spring™ pipeline repair installations. To mark the occasion we will participate in installation demos at the Pipeline Research Council International (PRCI) Technology Development Center (TDC) tours prior to PPIM on Monday, February 12th. PRCI has set up two tours in advance of PPIM, and roundtrip transportation will be provided from the George R. Brown Convention Center. Parking is also available at the TDC.

The TDC is a major commitment by the energy pipeline industry to provide a location to address key integrity concerns in our global pipeline systems. The TDC provides the industry with an independent third-party site to fully understand the capabilities of current tools and to guide the development of the new technologies needed to push towards that goal.

Virtual Trainings and Cost Savings

Dear Colleagues and Friends,

During these uncertain times, it is crucial that the transportation networks that supply our critical industries (like the medical sector) with energy remain operational. This requires that repairs be made when necessary to our pipelines.

One of Pipe Spring LLC’s core values is creating products that install easily and eliminate human error during application. During the development process of our integrity enhancement products and repairs, every effort was made to reduce field variables. We have a product that is simple to install and can be repeated time and time again. The effort that was undertaken during development now allows us to easily transition to completely remote trainings during this COVID-19 pandemic. We are able to provide virtual support 24/7 to our customers and set up instruction for those who need to install Pipe Spring™ units that do not already have an installer, trainer, or subject matter expert manufacturer certification. For our United States clients, this will meet your OQ requirement when a manufacturer certification is needed. For our international clients, we can work with you to satisfy your training requirements as well. We are prepared to offer FREE VIRTUAL TRAINING to the industry to assist during these unprecedented times.

It is also important to note that an installation can be made easily with only two people. Under certain circumstances, a single individual could install a unit by him/herself if needed. Current recommendations to combat COVID-19 advise that people should be in groups of ten people or fewer. We are pleased to be able to meet this recommendation even in routine circumstances.

Additionally, our products are a fraction of the cost of other repair technologies on the market. In the coming months, as we recover from this pandemic, our products will remain the most economical option for our clients.

To set up a virtual training and discuss your repair needs during this difficult time contact us today! We are here to help our industry get through these tough times and make necessary repairs to our infrastructure while remaining as safe as possible.

Be well friends,

Molly Laughlin Doran, Owner


FAQ Series: How Does Pipe Spring™ Work? What Integrity Threats Does Pipe Spring™ Address?

Question: How does Pipe Spring™ work?

Answer: The laminated steel sleeve reinforces the existing pipe.

For metal loss defects: The thinned section of the existing pipe will tend to display strain and will begin to bulge and yield in the radial direction due to internal pressure. A threat to the pipeline integrity exists. With a properly installed Pipe Spring™ sleeve, the thinned ligament utilizes the high compressive strength filler material to transfer the load to the laminated steel sleeve. The steel sleeve then shares the stress with the pipe. Metal loss defects cannot bulge and yield. Metal loss defects are effectively mitigated.

For integrity enhancement applications: Wet uncured filler material is placed around any weld or protuberance from the pipe surface. The thin layer steel is wrapped around then pipe with the adhesive system applied between each layer. Out-of-round or ovality of the pipe is addressed by the conformity of the thin layer steel and the filler. The system quickly transfers load to the resultant steel sleeve. The engineering parameters of the steel sleeve augmentation can be calculated for hoop and axial strength. This can be added to the known minimum value of the pipe (perhaps recent known pressure if the grade of the pipe is unknown). The effective fracture toughness of the laminated steel sleeve is extremely high. The reduction in stress via the augmentation and the fracture toughness of the augmentation can be utilized for calculations related to fracture mechanics. The laminated steel sleeve augmentation provides excellent mitigation of potential future third-party mechanical damage.

Question: What integrity threats does Pipe Spring™ address?

Answer: Pipe Spring™ is a modern version of a “Type A” sleeve with the welding eliminated and adhesive utilized to hold the sleeve (coil) together. The list of integrity threats which are properly addressed by a “Type A” sleeve is also the appropriate list for Pipe Spring™. In addition, Pipe Spring™ is adhered to the pipe via a high strength adhesive. Effective axial strength can be calculated as the lesser of the adhesive bond strength to the pipe or the axial strength of the steel sleeve for the appropriate cross-sectional area. Pipe Spring provides axial strength to mitigate threats with an axial component.
