The Difference Between ASTM A53 and ASTM A106 Seamless Steel Pipes

(1)ASTM A53 seamless steel pipe

ASTM A53 seamless steel pipe refers to a foreign standard steel pipe grade, that is, the American standard grade. A53-F corresponds to China's q235 material, A53-A corresponds to China's 10# material, and A53-B corresponds to China's 20# material.

Hot-rolled steel pipes are delivered in hot-rolled or heat-treated state.
The production process of hot-rolled seamless steel pipe: tube blank → heating → piercing → three-roll cross rolling, continuous rolling → pipe stripping → sizing → cooling → straightening → hydraulic test → marking → storage leverage effect seamless steel pipe will be Detect out.
The production process of cold drawn seamless steel pipe: tube blank → heating → perforation → heading → annealing → pickling → oiling → multi-pass cold drawing → blank tube → heat treatment → straightening → hydraulic test → marking → storage.
In terms of wall thickness, cold-drawn seamless steel pipes are better than hot-rolled seamless steel pipes, and the surface roughness is better.

Applications:
1. Buildings include: pipeline transportation at most, underground water extraction when building buildings, and boiler hot water transportation.
2. Mechanical processing, bearing sleeves, processing machinery accessories, etc.
3. Electrical: gas transmission, water power generation fluid pipeline.
4. Anti-static pipes for wind power plants, etc.

(2)ASTM A106 seamless steel pipe

ASTM A106 seamless steel pipe belongs to American standard steel pipe. A106 includes A106-A and A106-B. The former is equivalent to China's 10# material, and the latter is equivalent to China's 20# material. It belongs to the ordinary carbon steel series and is one of the commonly used materials.

ASTM A106 seamless steel pipe includes two processes: cold drawn and hot rolled. In addition to the different production processes, the two are different in accuracy, surface quality, minimum size, mechanical properties, and organizational structure. It is widely used in various industries such as petroleum, chemical industry, boiler, power station, shipbuilding, machinery manufacturing, automobile, aviation, aerospace, energy, geology, construction and military industry.
