What Is API 5L (line Pipe Specification) GRB Seamless Pipe?

Line pipe: It transports oil, gas, or water pumped out of the ground to oil and natural gas industrial enterprises through line pipes. Line pipes include seamless and welded pipes; their pipe ends include flat, threaded, and socket ends; their connection methods include end welding, coupling, socket, etc.

Main materials of line pipe: L245, L290, L360, L415, L480, GR.B, X42, X46, X56, X65, X70, X80, X100 and other steel grades.
