Test pressures shall be maintained for a <br />minimum of five seconds. <br />Nondestructive electric testing of the weld seam is <br />required on each length of ERW pipe NPS 2 and <br />larger. <br />Tensile Requirements <br />Tensile Strength, min. 60, 000 psi <br />Yield Strength, min. 35,000 psi <br />Bending Test (Cold) <br />For NPS 2 and under <br />Degree of Bend 900 <br />Diameter of Mandrel 12 x outside pipe diameter <br />Flattening Test <br />As a test for ductility of the weld for pipe 2-1/2" NPS <br />and larger, position the weld at 0° and alternately at <br />900 to the direction of force and flatten until the OD is <br />2/3 of the original outside diameter. No cracks shall <br />occur along the inside or outside surface of the weld. <br />All of our facilities have quality systems in <br />place. At a minimum, they're registered to <br />ISO 9001:2008 Quality Management Systems, <br />
