API5L PSL1 and PSL2 Carbon Seamless steel Pipeline Grade BC

API 5L PSL1 and PSL2 Carbon Seamless steel Pipeline Grade B/C

This Standard specifies requirements for the manufacture of two product specification levels (PSL1 and PSL2) of steel pipes for use in pipeline transportation systems in the petroleum and natural gas industries. This Standard is not applicable to cast pipe.The API 5L specification is generally more clear about the limits on dimensional deviations (end squareness, straightness of pipe, hockey-stick pipe, flared pipes), whereas the ASTM standards are more vague. Carbon steel pipe grades include: ASTM A53 grades A and B; ASTM A106 B and C; API5L grade B; API5L X42, X52, X60 and other high yield grades. Low temperature carbon steel […]
