Automatic High Precision Aluminum Round Square Rectangle Tube Pipe Making Machine

Introduction of Pipe Making Machine

HF63AL high frequency straight seam welded pipe set is a special equipment for producing high frequency straight seam welded aluminum or aluminum alloy pipes for automobile condenser pipes or structural pipes or industrial pipes. Its diameter is 12.7-Φ 63.5mm, and its wall thickness is δ 1.0-3.0mm. High precision and high speed production line can be achieved by optimizing design, material selection, precision machining and rolling. The production speed of the pipeline can be adjusted within the range of appropriate pipe diameter and wall thickness.

The strip with precise size, which is pre cut by high quality aluminum or aluminum alloy coils on the slitter, is fed into the pipe rolling mill, and gradually forms a circular section with an opening joint along its length in the pipe rolling mill.

The high frequency induction welding technology is used to heat the weld edge and weld the longitudinal seam to form a continuous weld.

The steel belt is a circle formed by continuous seam welding. The welded pipe is further calibrated to the specified tolerance in the sizing machine by grinding and cooling the external weld bead.

After that, the endless welded pipe will be cut in the flow to the required and measured length.The finished pipe can be round, square or rectangular.

Summary of Pipe Making Machine

1. Pipe making machine has three types: Stainless Steel Pipe Making Machine, High Frequency Pipe Welding Machine and ERW Pipe Welding Machine.

2. One machine can produce round, square and rectangle pipes.

3. Our pipe making machine material use very thick steel, rollers are all use Cr12, shafts use 40CrMov. All material adopts heat treatment.

4. All electrical accessories are international brands we use.
