Northwest Pipe Company announced that the United States Patent and Trademark Office has issued U.S. Patent No. 12215817 for its innovative InfraShield® Joint System. This system is a Geohazard Resistant Steel Pipe (GRSP) solution designed to enhance the resilience of steel pipelines in geologically vulnerable areas. The InfraShield® system offers a fully welded, easy-to-install solution for C200 steel pipe, ensuring leak-free reliability and delivering cost savings. It utilizes a strain-based design with a small projection in the steel pipe wall to absorb deformation from differential settlement or seismic activity without over-stressing the lap-welded joint. This patented technology is designed to withstand challenging geological conditions, including seismic activity, landslides, and soil movement, making it an essential solution for critical water infrastructure projects. The patent reinforces Northwest Pipe Company's leadership in developing advanced water transmission solutions that provide lasting performance and value.
