ASTM A53 Large Diameter Seamless Steel Tube

widely used in petroleum, chemical, medical, food, light industry, machinery, instrument and other industrial pipeline and mechanical structure parts, etc.


ASTM A53 seamless steel pipe refers to the steel pipe grade of foreign standards, that is, American Standard. A53-f corresponds to domestic Q235 material, a53-a corresponds to domestic 10# material, and a53-b corresponds to domestic 20# material.
Production process of hot-rolled seamless steel pipe: billet → heating → perforation → three roll cross rolling and continuous rolling → pipe stripping → sizing → cooling → straightening → hydrostatic test → marking → warehousing lever effect seamless steel pipe will be detected.
Production process of cold drawn seamless steel pipe: pipe blank → heating → perforation → heading → annealing → pickling → oiling → multi pass cold drawing → blank pipe → heat treatment → straightening → hydrostatic test → marking → warehousing.
In terms of wall thickness, cold drawn seamless steel pipe is more uniform than hot-rolled seamless steel pipe, and the surface roughness is better.
Application:
1. Buildings include: most underground pipelines are transported, underground water is extracted during building construction, boiler hot water is transported, etc.
2. Machining, bearing sleeve, machining machinery accessories, etc.
3. Electrical: gas transmission, water power generation and fluid pipeline.
4. Anti static tube of wind power plant, etc
