API 5L X65 PSL2 pipes are a type of steel pipe widely used in the transportation of oil, natural gas, and other fluids in the energy industry. These pipes adhere to the API (American Petroleum Institute) 5L specification, specifically the PSL2 (Product Specification Level 2) level, which signifies a higher level of quality and performance compared to PSL1. API 5L X65 PSL2 pipes are available in various sizes, ranging from 2 3/8 inches to 42 inches in diameter, and with wall thicknesses ranging from 0.154 inches to 2.500 inches. The steel used in their construction is of grade X65, characterized by its strength and durability.
In terms of chemical composition, API 5L X65 PSL2 pipes typically contain carbon in the range of 0.12% to 0.24%, silicon between 0.15% and 0.45%, and manganese within 1.00% to 1.60%. They have strict limits for impurities, with maximum allowable levels of phosphorus at 0.025% and sulfur at 0.015%. Other alloying elements like chromium, nickel, copper, molybdenum, titanium, vanadium, and niobium are present in limited quantities, contributing to the pipes' overall properties. The mechanical properties of API 5L X65 PSL2 pipes are well-defined, with a minimum yield strength of 65,300 psi (450 MPa) and a minimum tensile strength of 77,500 psi (535 MPa). They exhibit a minimum elongation of 22% and have a maximum hardness of 250 HBW. To ensure their suitability for the intended applications, these pipes undergo Charpy V-notch impact testing at 32°F (0°C) with a minimum energy absorption of 32J (23.6 ft-lbf).
