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 actively 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 developing recommendations for coating procedures on internal welds after backfill is in place. The Pipe Quality Audit Certification is a major accomplishment achieved by many STI/SPFA pipe fabricators.
Pipe Quality Audit Certification Program
The Steel Plate Fabricators Association (SPFA) is a joint organization with the Steel Tank Institute, or STI/SPFA. It is a national organization serving the water market since 1916 as developers of standards and certification programs for quality, safety, and reliability in the manufacture and testing of steel piping, tanks, and pressure vessels.
The STI/SPFA Pipe Quality Certification is a requirement in most piping specifications in the United States water transmission industry. Unlike other international certification programs, the STI/SPFA 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, and engineering and procurement practices.
