Application field
630mm×5mm stainless steel seamless pipe is a high-performance, high-corrosion-resistant and high-strength pipe with good physical and chemical properties. It is widely used in petroleum, chemical, pharmaceutical, food, aerospace, shipbuilding, automobile and other fields.
In the petroleum industry, stainless steel seamless pipes are widely used in oil wells, drilling platforms, refineries, oil pipes, oil storage tanks and other equipment, mainly used to transport liquids and gases such as oil and natural gas. Due to the large amount of corrosive substances contained in oil and natural gas, the corrosion resistance and high temperature resistance of pipes are highly required. 630mm×5mm seamless inox tubing is the first choice for these industries.
In the chemical industry, stainless steel seamless pipes are widely used in chemical equipment, chemical pipelines, chemical storage tanks and other equipment, mainly used to transport chemicals, acids, alkalis and other liquids and gases. Due to the corrosive nature of chemicals, the requirements for corrosion resistance and high temperature resistance of pipes are also very high. 630mm×5mm stainless steel seamless pipes are the main pipes in the chemical industry.
In the pharmaceutical industry, stainless steel seamless pipes are widely used in pharmaceutical equipment, pipelines, storage tanks and other equipment, mainly used to transport drugs, biochemical products and other substances. Due to the high purity requirements of pharmaceuticals and biochemical products, the requirements for the hygienic performance and corrosion resistance of the pipes are also very high. Stainless steel seamless pipes are the main pipes in the pharmaceutical industry.
In the food industry, stainless steel seamless pipes are widely used in food processing equipment, pipelines, storage tanks and other equipment, mainly used to transport food, beverages and other substances. Due to the high hygienic requirements of food and beverages, the hygienic performance requirements for pipes are also very high. 630mm×5mm stainless steel seamless pipes are the main pipes in the food industry.
Production process
The production process of 630mm×5mm seamless inox tubing mainly includes hot rolling, cold drawing, cold rolling and other processes.
The hot rolling process is to heat the stainless pipe billet to a certain temperature (usually above 1100°C) and then roll it. First, the billet is sent into a heating furnace for heating, then rolled, formed by a rolling mill, and finally annealed to eliminate residual stress and improve mechanical properties. The hot rolling process has the advantages of high production efficiency, high rolling force, and a wide range of forming sizes, but the surface quality is poor, and subsequent surface treatment is required.
The cold drawing process is to directly draw the stainless steel blank into shape. First, the billet is heat-treated, and then drawn and formed by a drawing machine. No heating is required during the drawing process, so the precision and surface quality of the stainless steel seamless pipe can be guaranteed. The cold drawing process has the advantages of high precision, high surface quality, and stable dimensions, but the cost is high and the production efficiency is low.
The cold rolling process is to roll the stainless pipe billet at room temperature. Firstly, the blank is pickled, then rolled and formed through a rolling mill, and finally pickled and degreased and cold drawn to improve surface quality and precision. The cold rolling process has the advantages of high surface finish, high dimensional accuracy, and high forming efficiency, but the cost is relatively high.
Matters needing attention
1. When using 630mm×5mm seamless inox tubing, care should be taken to avoid excessive bending and excessive extrusion, so as not to cause deformation and rupture of the pipe.
2. When performing welding, cutting and other processing, care should be taken to select appropriate processes and equipment so as not to affect the performance and life of the pipe.
3. During storage and transportation, care should be taken to avoid mechanical damage and corrosion of the pipes, so as not to affect the quality and service life of the pipes.
Conclusion
630mm×5mm stainless steel seamless pipe is a high-performance, high-corrosion-resistant and high-strength pipe with good physical and chemical properties. It has a wide range of applications in petroleum, chemical, pharmaceutical, food, aerospace, shipbuilding, automobile and other fields application. In the process of use and handling, we need to pay attention to follow some basic precautions, so as not to affect the performance and life of the pipe. With the continuous development and progress of industrial technology, seamless inox tubing will have a broader application prospect.
