api5l 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). Also, the quality grades are more stringent when API 5L Line Pipe PSL2 is applied where as rolled grades are not acceptable and rework is not allowed. Moreover, particular attention is given to toughness and toughness tests for sour services and higher pressure/ temperature classes.
