　　The API SPEC 5L specification is a standard by the American Petroleum Institute. The Api 5l X56 Erw Line Pipe is produced in two specification levels i.e. - PSL 1 and PSL 2. While the Ap
i 5l X56 Psl1 Seamless Pipe is a standard for all pipes, PSL2 is a stricter, more detailed level that includes chemical, mechanical properties, and testing requirements of the Api 5l X56 Psl2 Seamless Pipe. This specification provides standards for Api 5l X56 Psl2 Carbon Steel Erw pipe, which is well suited to be used in applications such as the conveyance of media like gas, water, and oil.

　　Hence, the api 5l x56m psl2 pipe is useful in the natural gas and oil industries. The API SPEC 5L covers steel alloy line pipes with both seamless as well as welded construction. The Api 5l Grade L390 Carbon Steel Seamless Pipe includes plain ended, belled end pipe, and threaded end, as well as through the flowline or as referred to in short as TFL pipe. The standard also includes Api 5l X56 Psl 2 Carbon Steel Seamless Pipes with ends prepared for use with special couplings. The two digit number that is mentioned after the letter ‘X’ in Api 5l X56 Psl 2 Carbon Steel Pipe is indicative of its yield strength in 000's psi. Hence, the yield strength of Api 5l X56 Psl2 Welded Line Pipe is 56000 psi.

　　Manufacturers are particularly attentive to the toughness properties as well as the toughness tests to be conducted on the Api 5l Grade X56m Psl2 Material for sour services and higher pressure & higher temperature classes.
