Tensile Test - NPS 8 and larger - either transverse or longitudinal acceptable Smaller than NPS 8 - weighed in lots. Pressure is maintained for not less than 5 seconds. Maximum Pressures are not to exceed 2500 psi for NPS3 and must stay under 2800 psi for the larger sizes. Inspection test pressures produce a stress in the pipe wall equal to 60% of specified minimum yield strength (SMYS) at room temperature. Outside Diameter at any point shall not vary from standard specified more than: NPS Permissible Variations in Outside Diameter Larger sizes shall be weighed separately by length. NOTE - NPS 4 and smaller - weighed in lots. Weight of any length shall not vary more than 10% over and 3.5% under that specified. Permissible Variations in Weights per Foot The minimum wall thickness at any point shall not be more than 12.5% under the nominal wall thickness specified. Total of Cr, Cu, Mo, Ni, and V shall not exceed 1% Hot-finished pipe need not be heat treated.Ĭold-drawn pipe shall be heat treated after the final cold draw pass. Steel cast in ingots or strand cast is permissible. Killed steel, with primary melting process being open-hearth, basic-oxygen, or electric-furnace, possibly combined with separate degassing or refining. NPS 2″ and larger shall be hot finished unless otherwise specified.
NPS 1-1/2″ and under may be either hot finished or cold drawn.
