ERW273 H.F. Straight Welded Pipe Production Line
Description
ERW tube mill is also called high-frequency longitudinal welded pipe production line. Suitable materials are hot-rolled or cold-rolled strip coils such as plain carbon steel and high-strength steel, etc.
The strip steel is unrolled by the uncoiler, and then enters the accumulator storage after passing through the shear butt welding machine. The strip steel is extruded by rollers and divided into two parts: break-down section and fine pass section. After high-frequency induction welding and sizing part, output the required length of pipe, cut off by flying saw, and finally stack and pack the steel pipe. This production line is a comprehensive complete production line for continuous welding of steel strips into pipes, mainly composed of uncoiler, shear & end welder, accumulator, forming & sizing machine, H.F welder, flying saw, stacking & packing machine.
If there are special purposes or requirements for steel pipes, it is necessary to add testing equipment, such as hydraulic testing machine, intermediate frequency annealing machine, ultrasonic flaw detection machine, etc.
High frequency welded pipe production line is mainly used for continuous production of straight seam welded pipe. It adopts high-frequency induction welding, which can not only produce round pipe but also corresponding square pipe and special-shaped pipes. The high-frequency pipe welding machine is mainly used for the production of various iron pipes, construction pipes, structural pipes, water pipes, oil pipes, API Pipes, and so on.
