Production process of welded pipes

1. Material preparation: The materials for welded pipes include wide steel strips, hot-rolled steel strips, cold-rolled steel strips, etc. These materials need to be cut, leveled, and cleaned according to process requirements to meet the quality requirements of finished welded pipes.

2. Curling forming: The processed steel strip is formed into a relatively small diameter tube through a curling machine.

3. Welding process: High frequency induction welding or resistance welding process is used to weld the curled tube into a long welded pipe.

4. Steel annealing: Through steel pipe annealing treatment, the hardness of the steel pipe is reduced, and the stress level and internal stress of the finished welded pipe are reduced.

5. Size cutting: Cut the long welded pipe into the required length according to the process requirements.

6. Fine repair process: Further fine repair the cut welded pipe, including straightening, trimming, processing and other processes.

7. Coating treatment: According to the usage environment, the outer wall of the welded pipe is coated to improve its corrosion resistance, wear resistance, and corrosion resistance.

Application fields of welded pipes

1. Construction field: Welded pipes, as a type of building material, are widely used in building structures, steel structures, pipelines, power poles, highway guardrails, etc.

2. Automotive manufacturing field: Welded pipes are widely used in automotive manufacturing, including frames, chassis, exhaust pipes, etc.

3. Industrial manufacturing field: Welded pipes are also widely used in industrial manufacturing fields such as machinery, ships, and airplanes, with good strength and corrosion resistance.

In short, welded pipes, as an important metal material, have a wide range of production processes and application fields. The process of manufacturing welded pipes requires strict control to ensure the quality of finished welded pipes. In the field of application, the application scope of welded pipes is constantly expanding and has a wide market prospect.
