Evonik and United Poly Systems Team to Extrude PA12 VESTAMID® NRG Natural Gas Pipelines
Evonik and United Poly Systems Team to Extrude PA12 VESTAMID® NRG Natural Gas Pipelines
United Poly Systems is extruding natural gas pipelines made of Evonik’s PA12 VESTAMID® NRG
United Poly Systems is the newest extrusion partner for Evonik’s PA12 VESTAMID® NRG thermoplastic. VESTAMID® NRG is approved for gas distribution piping through the regulations of the Pipeline and Hazardous Materials Safety Administration (PHMSA). VESTAMID® NRG operates at pressures up to 250 psi, is highly resistant to heavy hydrocarbons, and can be joined with proven butt fusion or electrofusion methods. According to Terry McConnell, Evonik’s Business Development Manager, “We are confident that PA12 piping will set a new standard in this industry; as it can be used at higher operating pressures than polyethylene, has no chemical derations, has a higher temperature performance and has little-to-no permeation issues. With United Poly Systems as our newest extrusion partner, we have gained a dedicated and flexible production and sales team that cares as much about quality standards as we do."
United Poly Systems manufactures pipes with diameters from ¾” to 26” IPS and 4” to 24” DIPS out of their facilities in Springfield, Missouri and Albuquerque, New Mexico. Their exclusive territories for this agreement include Alabama, Arizona, Arkansas, Colorado, Kansas, Louisiana, Mississippi, New Mexico, Oklahoma, Texas, Utah, and Wyoming.

Video Comparison of Electrofusion and Butt Fusion Joining Techniques
Video Comparison of Electrofusion and Butt Fusion Joining Techniques
Aquatherm has put together a video comparing electrofusion and butt fusion
Aquatherm, manufacturer of polypropylene pipe, has put together a video that compares electrofusion and butt fusion joining. It is a great introduction for anyone who may not be familiar with the two joining techniques, including when to use each method. According to Aquatherm, butt fusion is the most common method used to join two pipes. Electrofusion is useful in spaces where a repair must be made or when working in a space that is too small for the butt fusion equipment. In both cases, care should be taken to prepare the pipes properly for fusion. When using butt fusion, cooling times can be reduced by up to 50% provided the pipe is supported until the time is up. In contrast, butt fusion requires that the pipes receive no mechanical stress on the weld for the full heating and cooling times. In Aquatherm’s demonstration, the butt fusion method took 10-12 minutes for the entire process while electrofusion took just over 40 minutes, a significant difference to consider when deciding which method to use. Both joining methods are very useful, but you should look at the requirements of your jobsite to choose the best option for your project.
