Types and uses of stainless steel pipes

1. The first difference between national standard pipes and non-standard pipes is the difference in quality standards. National standard stainless steel pipes are produced in accordance with national unified industry standards. There are corresponding standards for both the thickness and specifications of stainless steel pipes, but there is no unified industry standard for non-standard pipes.
2. The specifications of national standard pipes and non-standard stainless steel pipes are different. Stainless steel pipe manufacturers produce many kinds of national standard pipe specifications. Generally, many specifications can be found in the stainless steel pipe market, while the specifications of non-standard stainless steel pipes are generally designed and derived according to your own needs. The stainless steel pipes that come out, such as stainless steel pipes used as accessories for certain equipment, will have their own specifications and often need to be customized.
3. Different uses. The specifications of national standard stainless steel pipes determine its wider range of uses. Many industries can use national standard pipes, such as mechanical equipment, auto parts, hardware products, sanitary ware, etc. However, the specifications of non-standard stainless steel pipes are generally born to meet the needs of a certain type of product, so they are only used within their own scope, such as the thickness and specifications of stainless steel round pipes used by manufacturers of cloth rolling machine equipment, etc. The data needs to be determined according to their equipment usage standards, which also limits the use scope of this stainless steel round pipe.
According to different surface conditions, it can be divided into hot-rolled stainless steel pipes, cold-rolled stainless steel pipes and stretched stainless steel pipes. Hot-rolled stainless steel pipes have a smooth surface, high plasticity, toughness and mechanical strength, are resistant to corrosion by acids, alkaline gases, solutions and other media, are easy to process, and have good ductility. The thickness of cold-rolled stainless steel pipe is more precise, the surface is smooth and beautiful, and it also has various superior mechanical properties, especially in terms of processing performance. Stretched stainless steel pipes have high strength and precision and are suitable for high-precision mechanical structures.
According to different application fields, it can be divided into petroleum stainless steel pipes, chemical stainless steel pipes, food stainless steel pipes, electric power stainless steel pipes, decorative stainless steel pipes, etc. Petroleum stainless steel pipes have high corrosion resistance and high temperature stability, and are suitable for oil field mining and petrochemical industries. Chemical stainless steel pipes have high corrosion resistance and wear resistance and are suitable for chemical production and transportation. Food stainless steel pipes have high hygiene and corrosion resistance and are suitable for food processing and transportation. Power stainless steel pipes have high electrical insulation and corrosion resistance and are suitable for power engineering and power transmission fields. Decorative stainless steel pipes have low requirements and are mainly used in engineering decoration, construction, structure, etc.
According to different constituent elements, production methods, surface conditions and application fields, stainless steel pipes can be divided into many types, each with special properties and characteristics.
