API 5L X42 (L290) pipeline steel has a minimum yield strength 290Mpa. The tensile strength of welded
Steel pipe: ≥415Mpa.
Product classification level: PSL (Product Specification Level): specifies two product specification levels (PSL1 and PSL2). They have different levels of standard technical capacity requirements. PSL2 has mandatory requirements for carbon equivalent, notch toughness, maximum yield strength, and maximum tensile strength.
