Steel Water Pipe
STI/SPFA members build steel water pipe that meets or exceeds the requirements of ASCE, AWWA, SWPMTAC, and all industry standards for water transmission. The welded steel pipe built by Members is available in diameters up to 180 inches under either internal or external pressure.
STI/SPFA members are involved in standards development activities and have written several design manuals, developed design software, and are actively involved in research projects testing joint efficiencies and recommending coating procedures on internal welds after backfill is in place.

SPFA Pipe Quality Certification Program
The SPFA Pipe Quality Certification is a requirement in most piping specifications in the United States water transmission industry. The program addresses quality assurance and control, lining and coating operations, and equipment and welding procedures specific to steel water piping. The certification process also evaluates a company’s management, organization, engineering and procurement practices.
Steel Pipe Tech Library
STI/SPFA members have written several design manuals, presented technical papers addressing important issues and are actively involved in research and development projects.

Steel Water Pipe Presentation
The STI/SPFA Steel Water Pipe Section members created a presentation to educate you and your customers on the use and benefits of steel pipe.
Steel Water Pipe Century Club
STI/SPFA honors utility management companies or agencies whose steel water pipe or pipeline has been in continuous service in the water delivery infrastructure for more than 100 years. This honor demonstrates the strength and durability of steel for use in the water infrastructure. With rising concern about the aging of infrastructure components across the nation, STI/SPFA’s Steel Water Pipe Century Club recognizes utilities that have properly maintained their steel pipe components, resulting in 100 years or more of uninterrupted delivery of clean drinking water critical for sustaining community growth, commercial growth, industrial growth and, most importantly, for sustaining life.
