Schedule 40 pipe is produced from steel manufactured by electric furnace, open hearth, or basic oxygen processes. The steel is of soft weld able quality. Welded pipe NPS 4 and lower may be butt welded. Welded pipe over NPS 4 is typically electric welded. Standards: ASTM F1043 Strength and Protective Coatings for Metal Industrial Chain Link Fence Framework, Group I-AASTM F1083 Pipe, Hot-Dipped Zinc- Coated (Galvanized) Welded for Fence Structures, ASTM F567 Installation for Chain Link Fences, ASTM A 90/A90M Test Method for Weight of Coating on Zinc-Coated (Galvanized) Iron or Steel Articles Galvanized Steel Framework: The information contained herein for hot-dipped galvanized welded steel pipe covers the requirements for pipe sizes NPS 1 to NPS 8. (Note: The dimensionless designator NPS is used instead of traditional terms such as nominal diameter, size, and nominal size.) Tensile Requirements: The tensile strength of schedule 40 pipe is 48,000 psi (330 MPa), min.The yield strength of schedule 40 pipe is 30,000 psi (205 MPa), min. Coating Requirements: The minimum zinc coating weight of schedule 40 pipe is 1.8 oz./ft2 (550 g/m2), determined from the average results of two specimens taken for test, and not less than 1.6 oz./ft2 (490 g/m2) for either of these specimens. The weight of zinc coating is calculated by dividing the total weight of zinc, inside plus outside, by the total area, inside plus outside, of the area coated. Schedule 40 pipe with a minimum average zinc coating weight of 2.0 oz./ft2 (610 g/m2) is also available. Each specimen shall have not less than 1.3 oz./ft2 (400 g/m2) of zinc coating on each surface, calculated by dividing the weight of zinc on a given surface (inside or outside) by the area of the surface coated (inside or outside). The weight of zinc coating is determined in accordance with ASTM A90/A90M.
