Steel pipe according to the production method can be divided into two categories: seamless steel pipe and welded steel pipe, welded steel pipe referred to as welded pipe.
1 Seamless steel pipe according to the production method can be divided into: hot rolled seamless pipe, cold drawn pipe, precision steel pipe, hot expansion pipe, cold spinning pipe and extruded pipe.
Seamless steel pipe is made of high-quality carbon steel or alloy steel, hot rolled, cold rolled (drawn) points.
2. The welded steel pipe is divided into furnace welded pipe, electric welding (resistance welding) pipe and automatic arc welding pipe because of its different welding forms, which are divided into straight seam welded pipe and spiral welded pipe, and because of the shape of its end is divided into circular welded pipe and shaped (square, flat, etc.) welded pipe.
Welded steel pipe is rolled into a tubular steel plate to seam or spiral seam welding, in the manufacturing method, and is divided into low pressure fluid transportation of welded steel pipe, spiral welded steel pipe, direct coil welded steel pipe, electric welded pipe and so on. Seamless steel pipes can be used in various industries such as liquid pressure pipes and gas pipes. Welded pipes can be used for water pipelines, gas pipelines, heating pipelines, electrical pipelines and so on.

1. Raw material selection: The raw material of steel pipe is mainly billet, which can be hot-rolled coil, cold-rolled coil or steel pipe billet. In the selection of raw materials, it is necessary to consider the use and performance requirements of the steel pipe and select the appropriate steel.
2. Melting: Put the selected steel into the furnace for melting, melt the steel through high temperature, so that it becomes liquid. It is necessary to control the furnace temperature and the furnace atmosphere in the smelting process to ensure the quality of the steel.
3. Rolling: The molten steel is formed into steel tube billet by continuous casting or rolling process. Continuous casting is to inject liquid steel into a continuous casting machine and obtain continuous billets through cooling and solidification. Rolling is to pour the molten steel into the steel pipe mold, and get the steel pipe billet after many times of rolling and cooling.
4. Molding: The steel pipe blank is specifically formed into the desired steel pipe shape by the forming machine. There are many kinds of forming methods, such as hot rolling, cold rolling, cold drawing, cold bending and so on. Different forming methods will affect the precision and surface quality of the steel pipe.
5. Welding: For the steel pipe that needs to be welded, the steel pipe blank is welded. Common welding methods are resistance welding, arc welding, high frequency welding and so on. After welding, non-destructive testing and heat treatment of the weld are required to ensure the welding quality and the overall performance of the steel pipe.
6. Surface treatment: The surface treatment of the steel pipe to improve its corrosion resistance and beauty. Common surface treatment methods include galvanizing, spraying, polishing, etc.
7. Quality control: In the entire production process, quality control is very important. Through strict quality control measures, such as testing raw materials, monitoring the production process, non-destructive testing, etc., to ensure that the quality of the steel pipe meets the standard requirements.
Steel pipe production is a complex process, involving many links and technologies. Only through scientific production process and strict quality control can we produce high-quality steel pipe products. Therefore, when selecting steel pipe suppliers, manufacturers with professional production equipment and rich experience should be selected to ensure the quality and performance of steel pipes.
All in all, the production process of steel pipe includes raw material selection, melting, rolling, welding, surface treatment and other links. Through scientific production process and strict quality control, high-quality steel pipe products can be produced to meet the needs of various fields.
5.Product Application:
Steel pipe is mainly used in the following industries:
1. the construction industry
As one of the basic materials of construction, steel pipe is widely used in the structure of buildings, support rods and pressure transmission pipes. For example, large roof frames in buildings, support structures in high-rise buildings, etc., need to use large-caliber, high-strength steel pipes. In addition, in the construction of municipal roads, steel pipes are also the preferred materials for pipeline transmission such as rainwater, sewage, and gas.
2. the energy industry
The application of steel pipe in the energy industry is mainly reflected in the oil and gas pipelines, which can withstand the special environment of high temperature and pressure to ensure the safety and stability of energy in the transmission process. The characteristics of steel pipe, such as long life, low maintenance cost and high adaptability, make it widely favored in this field.
3. Petrochemical industry
In the petrochemical industry, steel pipes, as an important tool for transporting raw materials, semi-finished products and finished products, are widely used in chemical pipelines, oil pipelines and natural gas pipelines. For example, the cooling pipes used in the oil drilling process, the treatment pipes in chemical plants, etc., are selected to apply steel pipes.
4. Automobile manufacturing industry
The application of steel pipe in the automobile manufacturing industry is mainly reflected in the aspects of automobile racing, automobile chassis, engine exhaust pipe and structural parts. Compared with other materials, steel pipe has excellent strength and toughness, and can be well adapted to the needs of automobile manufacturing after processing.
In summary, the application field of steel pipe in modern industry is very wide, and it is an indispensable element in modern industry.
