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.

A283 carbon steel pipe is widely used in buildings and engineering structures. It is used for making steel bars or building workshop frames, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc., and is also widely used as mechanical parts with low performance requirements.

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.

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.

Rebar is commonly known as hot rolled ribbed bar. The grade of ordinary hot rolled steel bar consists of the minimum yield point of HRB and grade. H, R and B are the first letters of hotrolled, Ribbed and Bars respectively. Rebar can be divided into three categories according to strength :HRB300E, HRB400E, HRB500E, HRB600E, etc.
