Northwest Pipe secures patent for resilient pipe system

VANCOUVER, Wash. - Northwest Pipe Company (NASDAQ:NWPX), an established manufacturer specializing in water infrastructure with a market capitalization of $502 million, has been granted a U.S. patent for its InfraShield® Joint System, a new technology aimed at enhancing the resilience of steel pipelines in areas prone to geohazards. According to InvestingPro data, the company maintains a perfect Piotroski Score of 9, indicating exceptional financial strength.

The InfraShield® system, now patented under U.S. Patent No. 12215817, is a Geohazard Resistant Steel Pipe (GRSP) solution that strengthens pipelines against differential settlement and seismic activities without relying on gasketed joints. The product is touted for its fully welded, easy-to-install design that provides leak-free reliability and potential cost savings. This innovation comes as Northwest Pipe demonstrates strong financial performance, with InvestingPro reporting a 67% return over the past year and healthy revenue growth of 9.5%.

According to Scott Montross, President and CEO of Northwest Pipe Company, the InfraShield® represents a significant innovation in pipeline technology, offering unparalleled protection against geohazards while ensuring the long-term reliability that is crucial for water utilities and municipalities. The company’s engineering team has dedicated several years to the development of this system, which is designed to absorb deformation through a unique strain-based design, incorporating a small projection in the steel pipe wall to handle stress from geological movements.

The InfraShield® Joint System is expected to be a key solution for critical water infrastructure projects, especially in regions with challenging geological conditions such as areas with frequent seismic activity, landslides, and soil movement.

Northwest Pipe Company, founded in 1966 and headquartered in Vancouver, Washington, holds the title of North America’s largest manufacturer of engineered steel water pipeline systems. The company also produces a variety of other water-related infrastructure products, including those for stormwater and wastewater management, and operates 13 manufacturing facilities across the continent. With a current ratio of 3.2, the company maintains strong liquidity to support its operations.
