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 →
