what are tge differences between API 5L Gr B AND X42 PIPES
yes
API X70 is one of line pipe grade family define by API 5L specification
I am waiting for the answer
its a steel material used in pipes
API 5l X52
API 5L is a norme, A106 is a grade of steel 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 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.
what is pipe shall be as per API 5L PSL2 BNS
carbon steel pipe used for oil and gas transmissions
Modulus of elasticity will be 2.06*10^5 N/mm2
The step-by-step instructions on how to do a weld fitting on a A234 with a pipe of API 5L x60 w TH11.9 mm is not listed. It might be best to purchase a weld fitting manual for a A234 for further information.
10W-30 API SL or SM any name brand
can you weld two fittings have the specified the first is API 5L X60 and A234 WPHY60
