What are the production equipment for spiral welded steel pipes?

With the development of the construction industry, spiral welded steel pipes (SSAW) have become more and more widely used, and their excellent corrosion resistance and pressure resistance have become the first choice for many engineering projects. In the production process of spiral steel pipes, various equipment need to be used. Here are some common spiral welded steel pipe equipments.

1. Screw extruder
The screw extruder is the core equipment for spiral steel pipe manufacturing. It extrudes, wraps and shapes strip steel coils through multiple rollers in sequence to produce spiral tubes with high strength and toughness. There are many different types of screw extruders currently on the market: two-roller, three-roller and four-roller.

2. Edge cutting machine

The edge trimmer is a device designed to cut the edges of steel strips. The steel strips can be cut into specific sizes according to requirements. The manufacturing of spiral steel pipes requires the use of edge cutting machines, which can quickly and accurately cut the edges of the strip to ensure production efficiency and product quality.

3. Coating line
In order to improve the anti-corrosion performance of spiral steel pipes, a layer of anti-corrosion material is usually coated on the inside and outside of the steel pipe. The pipe coating line is a kind of equipment specially used for anti-corrosion coating. It can evenly apply the coating agent on the internal and external surfaces of the steel pipe, greatly improving the corrosion resistance of the spiral welded pipe.

4. Press roller machine
The roller press is a piece of equipment specially used to press steel pipes. By gradually rolling the steel pipe into the roller set, the steel pipe undergoes multiple deformations, thereby plastically deforming it into a steel spiral pipe of a certain size and shape.

5. Forming machine
The forming machine is one of the very important equipment in the steel spiral pipe production line. It can perform fast and accurate punching, cutting, blanking and other processing processes on the steel pipe according to different requirements and design specifications to ensure that the size and shape of the steel pipe meet the standards and requirements.

To sum up, steel spiral welded steel pipe equipment mainly includes spiral extruders, edge trimmers, coating lines, roller machines, forming machines, etc. The cooperation and use of these equipment can ensure the manufacturing quality of spiral pipes. and production efficiency.
