Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe production equipment, and more specifically, to a seamless steel pipe circulating cooling device. Background Art

[0002] Seamless steel pipe is a steel pipe formed by piercing a whole round steel, and the steel pipe without welds on the surface is called seamless steel pipe. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes and pipe jacking, etc. Seamless steel pipes are mainly used as oil geological drilling pipes, cracking pipes for petrochemical industry, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors and aviation.

[0003] The patent number is CN214078503U, a circulating cooling water system for seamless steel pipe production.
