With the development of the construction industry, spiral steel pipes 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 types of equipment are required. Below, carbon steel pipe manufacturers will introduce several common spiral steel pipe (SSAW) production equipment.
1. Roller press
The roller press, also known as the plate bending machine, is one of the key equipment for manufacturing spiral steel pipes. It bends the steel plate into a spiral profile through the rotation and adjustment of the rollers, and welds the two ends into one. The main parameters of the roller press include roller diameter, profile width, number of rollers, etc., which play a key role in the forming quality and production efficiency of spiral steel pipes.
2. Shearing machine
Shearing machine, also called plate cutting machine, is a device used to cut steel plates. In the production process of spiral steel pipe, the plate needs to be cut into the required length according to a certain size using a shearing machine, and then sent to the roller press for forming. The cutting accuracy, cutting speed and other parameters of the shearing machine will directly affect the forming effect of the spiral steel pipe.
3. Pipe welding machine
The pipe welding machine is a device that welds spiral steel pipes that have been formed at both ends. There are three main welding methods for spiral steel pipes: submerged arc welding, double-sided submerged arc welding and high-frequency welding. During the production process, different welding methods need to be selected according to steel pipes of different specifications and materials. The welding technology and equipment performance of the pipe welding machine have a direct impact on the quality and reliability of the spiral steel pipe.
4. Edging machine
The edge grinder is a device used to polish the welding joint. It can remove burrs and oxides from the welding joint to ensure the quality of the welding joint. Spiral steel pipes need to be welded multiple times during the production process, so they need to go through multiple edge grinding operations. The grinding method and grinding accuracy of the edge grinder have a significant impact on the appearance and mechanical properties of the spiral steel pipe.
5. Coating equipment
In order to improve the corrosion resistance and aesthetics of spiral steel pipes, internal and external
anti-corrosion coatings need to be treated during the production process. Coating equipment 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 steel pipes, greatly improving the corrosion resistance of spiral welded pipes. Commonly used coating materials include epoxy wax, polyethylene, polypropylene, etc. Coating equipment usually includes a coating process line for cleaning, spraying, oven and other treatments on spiral steel pipes.
To sum up, the production of spiral steel pipes requires the use of a variety of equipment such as roller presses, shearing machines, pipe welding machines, edge grinding machines and coating equipment. Each equipment has its own unique role. When purchasing these equipment, it is necessary to select different models and brands of equipment according to production needs, and pay attention to the performance and quality of the equipment to ensure the quality and efficiency of spiral steel pipe production.
