Mechanical Properties And Other Requirements

As per ASTM B407 specifications, the material should undergo chemical analysis test, mechanical properties test, grain size test, and hydrostatic or Nondestructive Electric test and adhere to all the limit range as specified like yield strength, tensile strength, and elongation requirements. The pipes and tubes are subjected to hydrostatic tests to determine the allowable fiber stress and to detect significant discontinuities such as drilled hole and transverse tangential notch.
