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.
API 5L is a specification from the American Petroleum Institute that covers the requirements for manufacturing steel pipe for transportation of oil and natural gas. The "5L" designation indicates the specific standard for line pipe used in the pipeline industry, focusing on the material properties, dimensions, and testing methods. The specification includes various grades, which indicate the pipe's strength and suitability for different applications.
what is pipe shall be as per API 5L PSL2 BNS
carbon steel pipe used for oil and gas transmissions
BNS in API 5L refers to "Black and Normalized Steel," which is a designation for the treatment of steel used in the manufacturing of line pipes. This process involves heating the steel to a specific temperature and then cooling it in air to enhance its mechanical properties, such as strength and ductility. The API 5L specification outlines the requirements for the manufacturing of steel pipes for the transportation of oil and natural gas, ensuring they meet the necessary standards for safety and performance.
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.
