Straight seam steel pipe is a common type of steel pipe, and its production process includes multiple steps. In this article, we will introduce the production process of straight seam steel pipe in detail, and the specific content of each step.

1. Raw material preparation

The production process of straight seam steel pipe starts with raw material preparation. The raw materials required for steel pipe production mainly include steel plates, steel strips, steel coils, etc. These raw materials need to be cut, turned, washed, etc. to ensure that their surfaces are smooth and free of oil and impurities.

2. Coil

Coiling is the second step in the production of straight seam steel pipes. In this step, the raw material is rolled into a certain shape for subsequent processing. Coiling can be done in a variety of ways, including hot rolling, cold rolling, hot dip galvanizing, etc.

3. Welding

Welding is the core step in the production of straight seam steel pipes. In this step, the coils are welded into one long tube. Welding can be performed in a variety of ways, including high frequency welding, arc welding, gas shielded welding, etc. Different welding methods have different advantages and disadvantages, which need to be selected according to the specific situation.

4. Cold roll

Cold rolling is the fourth step in the production of straight seam steel pipes. In this step, the welded long tube is cold rolled into a certain shape. Cold rolling can be done in a variety of ways, including cold bending, cold drawing, etc.

5. Cutting

Cutting is the last step in the production of straight seam steel pipes. In this step, cold-rolled steel pipes are cut to length. Cutting can be done in a variety of ways, including mechanical cutting, flame cutting, etc.

The above is the production process of straight seam steel pipe. In actual production, each step needs to be strictly controlled to ensure the quality and performance of the steel pipe. At the same time, it is also necessary to select appropriate raw materials and processing methods according to different needs and uses to meet customer needs.
