Description
The Φ140～Φ325×12mm straight seam welded pipe production line is used to produce straight seam welded steel pipes with a diameter of Φ140～Φ325mm and a wall thickness of 3～12mm. The equipment of each unit of the production line is based on the strengths of similar equipment at home and abroad, and has the advantages of reliable equipment performance, mature technology, and good structural strength. The application of advanced and mature FFX roll forming technology, PLC automatic control system, Siemens speed control unit and a number of new technologies ensure that the line has advanced technology, reliable operation, and convenient operation and maintenance. It is a contemporary domestic advanced production line with years Production capacity of 40,000 tons of welded steel pipes.

Process flow:
The stainless steel strip coil after slitting is hoisted into the preparation table or uncoiler on the coiling trolley → the trolley runs to the uncoiler → the uncoiler expands the cone to support the steel coil → the straight head machine rotates the rubber wheel to press down → straight head traction Machine work→head and tail leveling→shear butt welding (strip connection)→pit looper→edge milling→FFX rough forming→finish forming→ultrasonic plasma welding→outer bead leveling→sizing→solid solution Processing→fine sizing→turkey head straightening→band saw cutting→output→flat head chamfering→hydraulic test→collection.
