What is the difference between API 5L and ASTM A106 steel pipe?

API 5L is a norme for both seamless pipe and welded pipe, A106 is specially for seamless pipe. API 5L is a more comprehensive specification mainly developed for line pipes used in oil and gas industry; the range of strength grades is much wider. While the lower strength grades grades A & B are comparable to A106, the other grades have much higher strengths (e.g. X42, X56, X60,...etc). read more →

ASTM A106 pipe (also covered in ASME specifications as S/A 106) is the standard specification for ASTM A106 carbon steel pipe for high-temperature service. Most common uses are in refineries and plants when gasses or fluids are transported at high temperatures and pressures. read more →

Steel Pipe Manufacturing Process
Steel Pipe Manufacturing Process

The manufacture of steel pipe dates from the early 1800’s. Initially, pipe was manufactured by hand – by heating, bending, lapping, and hammering the edges together. The first automated pipe manufacturing process was introduced in 1812 in England. Manufacturing processes have continually improved since that time. Some popular pipe manufacturing techniques are described below. read more →
