100% Original Straight Seam Round Square Rectangular Pipe High Frequency Welding Machine ERW Tube Mill/Pipe Mill

Round Pipe Production on ZTZG Tube Mills: Our round pipe production utilizes shared rollers for the forming section, minimizing tooling changes on our tube mill line. Adjustment is made easy with electrical or automated controls. For the sizing section, rollers are quickly replaced using a side-pull trolley system.
Square Pipe Production on ZTZG Tube Mills: Similar to round pipe production, our square pipe forming section benefits from shared rollers. These shared rollers can be easily adjusted using either electrical or automated controls.

Description

ERW (Electric Resistance Weld) 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.

Steel pipe manufacturing process:
Scrolling Up→ Uncoiling → Shear and Welding→ Accumulator→ Forming→ HF induction Welding→ External Burr Removing→ Cooling → Sizing→ Flying Saw → Run Out Table →Inspecting→ Packing→ Warehouse

Features:
1.Suitable for processing GI, carbon steel and black steel tubes, etc.
2.Round and rectangular pipes can be produced with this equipment

3.Production speed can reach up to 120m/min
4.Diameter error tolerance is within 0.5/100 of the pipe's OD
