Spiral welded pipe unit, producing high-precision steel pipes!

2025-12-26
Latest company news about Spiral welded pipe unit, producing high-precision steel pipes!

The spiral welded pipe unit is a standard finalized unit developed and improved by Duolek Heavy Industry on the basis of absorbing the essence of foreign molding technology and combining with the actual situation in China. It is the most competitive and mature unit with technical characteristics of Duolek Heavy Industry.
The production process of spiral steel pipes is roughly as follows:
1. The raw materials for spiral steel pipes include strip steel coils, welding wire, and flux.
2. Before forming, the strip steel undergoes leveling, trimming, planing, surface cleaning, conveying, and pre bending treatment.
3. The use of a weld seam gap control device ensures that the weld seam gap meets the welding requirements, and the pipe diameter, misalignment, and weld seam gap are strictly controlled.
4. After cutting into single steel pipes, each batch of three steel pipe heads must undergo a strict initial inspection system to check the mechanical properties, chemical composition, fusion status, surface quality of the welded joints, and undergo non-destructive testing to ensure that the pipe manufacturing process is qualified before it can be officially put into production.
