The process flow of straight seam welding pipe production line
Blanking, groove processing, bending (head) - bending - joint - pre - in submerged arc welding, a clear root welding, submerged arc welding outside, nondestructive testing, the whole school, end processing
The company in the production of straight seam welding pipe production line mainly uses advanced technology to produce welding machine, high-frequency pipe equipment, pipe welding mold, pipe welding machine, manufacturing various types of pipe welding, known as pipe welding production line.
The straight seam welding pipe production line adopts hydraulic cylinder to manufacture the steel plate, and gradually bends the round pipe under the action of pushing and pressing roller. The two edges of the strip are heated to welding temperature by a high-frequency machine and then welded by extrusion. After that, the internal and external burrs formed by extruded metal on the internal and external surface of the steel pipe are removed by deburring. After a period of air cooling, the welded pipe is cooled by water, so that the welded pipe is no longer curved due to air cooling. The section of the steel pipe from the extrusion roll has a certain vertical ellipticity, and the outer diameter is slightly larger than the finished pipe. In order to obtain accurate outer diameter and section shape of steel pipe, after water cooling, the welding pipe of high frequency welder must be cooled and sized by sizing machine. The fixed length welded pipe is cut to a fixed length or double length in motion, subject to the corresponding tolerance requirements.
The company mainly produces various types of straight seam welding pipe production line also produces elbow machine, bending machine, three-way machine, pipe expanding machine, press, beveling machine and other molds, welcome customers to consult and order!
