Seamless steel tube production process

- Apr 19, 2019-

Seamless steel pipe production process: seamless steel pipe is mainly completed by reducing the tension, tension reducing process is hollow base material without mandrel continuous rolling process.On the premise of guarantee the quality of mother tube welding, welding tube tension reducing process is to welded pipe whole heated to 950 degrees Celsius above, then through the tension reducing mill (tension reducing mill a total of 24 times) rolled into a variety of outside diameter and wall thickness of the finished tube, adopt the process of hot rolled steel pipe have substaintial distinction with ordinary high-frequency welded pipe, through the heating furnace after its weld and the microstructure and mechanical properties of matrix can achieve the same in addition, through many times of tension reducing mill rolling and automatic control made the size precision of steel tube (especially the tube roundness and wall thickness accuracy) is superior to the same kind of seamless tube.
