Technological process

Description of the technological process of production of steel pipes slitting line APR. Sheet steel in rolls no more than 16000 kg, with a wall thickness of 0.2-4.75 mm. With an outer diameter of up to 1300 mm and an inner diameter of 400 mm, it is fed into the roll unwinding device by means of a crane. Where the drive rollers and the gear motor are used to unwind the roll and feed it to the slitting device, in which the sheet is cut into strips of a given size and parameters with disc knives. The cut strips are wound on the drum of the release structure, and with the help of a pusher, they are removed. The places where the strips are cut are carefully cleaned. The finished strips in rolls are weighed, marked and fed by car to the pipe welding mill. The line for the production of welded metal pipes can produce round and profile pipes Φ15 Φ Φ159mm, with a wall thickness of 0.2～4.75 mm, pipes with a square cross-section of 15*15 to 125*125mm, with a wall thickness of 0.2～4.75 mm, pipes with a rectangular cross-section of 20*30 to 80*120mm, with a wall thickness of 0.2～4.75 mm, The line has an innovative design, is equipped with parts and assemblies from the best Chinese and foreign manufacturers. Advanced technology, automatic PLC control, digital speed controller of the UK production ensures the stability of the line and the convenience of operation and maintenance.
