Steel Pipe&Tube having a hollow section whose length is much greater than its diameter or circumference. According to the section shape is divided into round, square, rectangular and shaped steel pipe; According to the material is divided into carbon structural steel pipe, low alloy structural steel pipe, alloy steel pipe and composite steel pipe; According to the use, it is divided into pipeline, engineering structure, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high pressure equipment with steel pipes, etc. According to the production process, it is divided into seamless steel pipe and welded steel pipe, of which seamless steel pipe is divided into hot rolled and cold rolled (drawn) two kinds, welded steel pipe is divided into straight welded steel pipe and spiral welded steel pipe.
Steel pipe is not only used to transport fluids and powdery solids, exchange heat energy, manufacture machinery parts and containers, it is also an economic steel. The use of steel pipes to manufacture building structure grids, pillars and mechanical supports can reduce weight, save 20 to 40% of metal, and can achieve factory mechanized construction. The manufacture of highway Bridges with steel pipes can not only save steel, simplify construction, but also greatly reduce the area of protective coating, saving investment and maintenance costs.
Steel pipes are divided into seamless steel pipes and welded steel pipes.
The production process of seamless steel pipe is to Pierce the solid tube billet or steel ingot into the hollow tube, and then roll it into the desired size of steel pipe. The different perforation and rolling methods used constitute different methods for producing seamless steel pipes. The production process of welded steel pipe is to bend the tube billet (steel plate or strip) into a tube shape, and then weld the gap to become a steel pipe. Because the molding and welding methods used are different, they constitute different methods for producing welded steel pipes.
Seamless steel pipe is mainly produced by hot rolling method. The extrusion method is mainly used to produce low-plastic high-alloy steel pipes or special-shaped steel pipes and composite gold pipes that are difficult to perforate. Cold rolling and cold drawing methods can continuously process hot rolled pipes into small diameter and thin-walled steel pipes. The welding steel pipe process is simple, the production efficiency is high, the cost is low, and the product variety is expanding.
Product Details
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.
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.
