A53 Carbon steel pipe
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.
ST42 Carbon steel pipe
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 .
4130 Carbon steel pipe
The better weldability also makes 4130 Carbon Steel Pipe a popular choice in the aerospace industry, which is used to manufacture commercial and military aircraft components requiring high strength and low weight. Examples include gears, piston pins, etc. Other uses of 4130 steel include auto parts, cutting tools and drilling machines.
API5L Carbon steel pipe
Main application: used for making oil and natural gas transmission pipelines. API 5L generally refers to pipeline steel plate -- API 5L pipeline steel plate. When the pipeline steel plate is processed into large-diameter pipeline steel pipe, the oil, steam and water pumped out of the ground are transported to the oil and natural gas industrial enterprises through pipeline pipes.
