Description
A seamless steel pipe is a steel pipe formed by piercing an entire round steel billet, with no welds on its surface, hence the name seamless steel pipe. Seamless steel pipes are mainly used as petroleum geological drilling pipes, cracking pipes for petrochemicals, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors and aviation. The production processes include pickling, cleaning, phosphating, saponification, cold drawing, head reforming, intermediate annealing, degreasing and rust prevention, annealing, straightening, flaw-detection inspection, pipe cutting and other stages, covering the energy consumption, material consumption, waste treatment and environmental emissions required during production. This dataset is formed by merging data from multiple sources.
Activity Description
The production process of seamless steel pipes includes cutting, (1250°C) perforation, heading, pickling, cleaning, phosphating, saponification, cold drawing, reforming, intermediate annealing (800~850°C), degreasing and rust prevention, annealing (800~850°C), straightening, flaw detection inspection, pipe cutting and other links, covering the energy consumption, material consumption, waste treatment and environmental emissions required in the production process.
Process Description
Seamless steel pipes are manufactured by piercing a whole round steel billet, resulting in pipes with no welds on the surface, which are called seamless steel pipes. They are mainly used as petroleum geological drilling pipes, cracking pipes for petrochemical industry, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors, and aviation.
