Welding Pipe Production Line
Welding Pipe Production Line
High frequency welding machine is a strip as raw material, after uncoiling, molding, high frequency welding, eliminate overip, sizing, straightening, cutting off a series of pipe forming process to produce complete sets of equipment or a variety of circular steel tube steel pipe line.
Roll forming is used to make the strip cold bending into round billet, and the welding seam is extruded to form round tube by high frequency induction heating. Various standard tubes and square tubes are produced after sizing.

| 7) Specification of saw piece | Φ50×Φ350×3.0mm | ||
| 8) Speed of saw piece | 87m/s | ||
| （6） | Automatic pipe unloading
platform |
It is an unloading platform of pipes cut by computerized saw. After the pipes falling down, workers can quickly check the quality and package them for preparation of transportation. | |
| （7） | High frequency induction
appliances |
Using the current skin effect and proximity effect of high frequency to make both edges of the material rapidly heated to soldering temperature and then weld them together. Using computer to monitor the process can provide the machine with reliable quality. | |
