Application: It is suitable for stress and pressure parts, as well as steam, water, gas and air pipelines for general purposes. A53 pipeline pipe belongs to American petroleum standard pipeline pipe. Pipeline pipe is used to transport oil, steam and water pumped out of the ground to oil and natural gas industrial enterprises through pipeline pipe. Pipeline pipe includes seamless pipe and welded steel pipe, with flat end, threaded end and socket end at the pipe end; The connection methods are end welding, coupling connection, socket connection, etc.
Performance and application of material ST37: the material has good performance, that is, through cold rolling, it can obtain cold rolled strip and steel plate with thinner thickness and higher precision, with high straightness, high surface finish, clean and bright surface of cold rolled plate in Taiwan Strait, easy to be coated, various varieties, wide application, high stamping performance, non aging, and low yield point.
The tensile strength of ST42 Carbon Steel Pipe shall not be less than 42kgf/mm2, which is 420MPa.ST42 Carbon Steel Pipe is a German standard seamless steel pipe, which is widely used. German standard seamless steel pipes for general purposes are rolled from ordinary carbon structural steel, low alloy structural steel or alloy structural steel, with the largest output, and are mainly used as pipes or structural parts for fluid transportation .
