Welded Steel Tube Workshop Design
Introduction
Welded steel tube is a kind of steel product widely used in various industries. It is made of low-alloy steel through hot rolling and cold forming process and can be used for boiler, pipe, fluid pipe, fluid pressure equipment, pipe for various transportation and engineering system components, etc. The processing of welded steel tube generally includes several complex processes such as unwinding, uncoiling, forming, welding and sizing. Welded steel tube workshop design needs to take into consideration the production scale, product types, technological process, equipments, auxiliary facilities and requirements of finished products.
Production scale
The scale of production is determined by the product type and output of welded steel tube workshop. Generally speaking, the production process of welded steel tube workshop is divided into three categories: forming, welding and sizing.
1.Forming process: it generally includes unwinding, uncoiling, straightening, forming and flying shear.
2.Welding process: it includes MIG and MAG welding and forming.
3.Sizing process: it is the process of modeling steel pipes by cold working and machining.
Product type
The product type and variety of welded steel tube workshop varies, and can include high-frequency welded pipe, low-frequency welded pipe, induction welded pipe and compound welded pipe. Generally speaking, the processes of forming and welding are the same, but the choice of equipment depends on the welded pipe type and thickness.
Technological process
The process of welding steel tube workshop involves physical and chemical operations. The physical processing steps include:
1.Unwinding process: it is the process of unwinding steel coil from the equipment and then putting it into the machine for uncoiling and straightening.
2.Forming process: it is the main process in the welded steel tube workshop, which consists of unwinding, uncoiling and forming the steel coil.
3.Welding process: it is the process of welding the steel pipe after forming. It includes MIG and MAG welding and forming.
4.Sizing process: it is the process of cold working and machining the formed steel pipe.
Equipments
The equipments used in the welded steel tube workshop include the forming machine, welding machine, cold working machine and other equipment, such as testing machine, laser cutting machine and bending machine.
Auxiliary facilities
Auxiliary facilities are usually installed in the welded steel tube workshop. Including air compressor, welding vessel and buffer tank, they can realize the production process, transmission and inerting effect of the workshop.
Requirements of finished products
The finished products of welded steel tube workshop are steel pipes, so the requirements of finished products are mainly the raw material and surface quality. The raw materials include the steel grades, steels codes, chemical composition, mechanical properties and dimensional tolerances. The surface quality includes surface appearance, surface roughness, straightness and shape deviations.
Conclusion
The design of welded steel tube workshop is complicated and many factors need to be considered. It includes production scale, product types, technological process, equipments, auxiliary facilities and requirements of finished products. In the construction process of welded steel tube workshop, the requirements of the design must be strictly followed, the safety and hygiene of the workshop should be paid attention to, and the quality of the finished products should meet the standards.
