ASTM A53 seamless steel pipe refers to the foreign standard steel pipe number, that is, the American mark number. A53-F corresponds to domestic Q235 material, A53-A corresponds to domestic 10 # material and A53-B corresponds to domestic 20 # material.






ASTM A53 seamless steel pipe is usually delivered in hot-rolled or heat-treated state; hot-rolled seamless steel pipe production process: billet heating piercing three-roll skew rolling, continuous rolling stripping sizing cooling leveling water pressure test marking leverage effect seamless steel pipe will be detected. Cold-drawn seamless steel tube production process: billet heating perforation start annealing pickling oil coating multi-channel cold drawing blank pipe heat treatment straightening water pressure test marking storage. The wall thickness of cold-drawn seamless steel tube is even better than that of hot-rolled seamless steel tube, and the surface roughness is also better.






Application of ASTM A53 Seamless Steel Pipe


1. There are many kinds of buildings: most underground pipelines are transported, groundwater is extracted when buildings are built, and hot water is transported by boilers.


2. Machining, bearing sleeve, processing machinery accessories, etc.


Electricity: Gas transmission, hydraulic fluid pipeline.


4. Antistatic tube of wind power plant.
