Most petroleum refining equipment and piping is constructed of carbon steel having a minimum specified tensile strength of up to 480 MPa (70,000 psi), and in nearly every case, the equipment is fabricated by welding. The welds for refinery equipment and piping are made to conform to various codes, and according to these codes, these carbon steels are classified as P-1, Group 1 or 2. Hence, in RP0472, they are referred to as "P-1 steels". ) environments
