Pipe Quality Certification Program

The Pipe Quality Audit Certification Program is a major accomplishment achieved by many STI/SPFA pipe fabricators. Apply for the Pipe Quality Audit Certification Program.

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, engineering and procurement practices.

The audit program is administered through a third-party quality assurance organization and requires rigorous inspection and re-certification every three years. By requiring STI/SPFA certification, owners and engineers can have confidence that their pipe and fittings will conform to both the defined requirements of the specifications and the intent of a quality product.
