Stainless steel pipe manufacturer & supplier in China: Unmatched Quality and Precision.
Stainless Steel pipe hot sale products: 304,304L,316,316L,304,304L,316,316LStainless steel pipes are the most popular products in the International market.
Compared with carbon steel pipe, stainless steel pipe is more anti-corrosive, more safe and reliable when it is used in high temperature or low temperature environment.
What is Stainless steel pipe?
Stainless steel pipe is a kind of durable material that is made of stainless steel. It has the advantage of good corrosion resistance, so it can maintain good stability in corrosive environments, such as humidity, acid and alkali.
According to the manufacturing process, there are stainless steel seamless pipe and stainless steel welded pipe two kinds; According to the shape, it is divided into stainless steel round pipe, stainless steel square pipe, stainless steel rectangular pipe three kinds.
Stainless steel pipe can be made into different shapes by various molding processes. In processing, there are cutting, welding, polishing and other processes to adapt to a variety of complex manufacturing needs. Stainless steel pipes are widely used in piping systems, construction and decoration, machinery manufacturing, chemical industry, etc.
Stainless Steel Pipe Type: As Per Manufacturing Process
Stainless steel seamless pipe
Stainless steel seamless pipe is made of steel ingot or solid bar through perforation to make wool pipe, and then made by hot rolling, cold rolling or cold drawing. There are also hot processing, cold processing, heat treatment processes and other processes. It has the characteristic of good chloride erosion performance, so it is mainly used in Marine environments.
Stainless steel welded pipe
Stainless steel welded pipe is made of stainless steel materials through welding processing, which is mainly made by welding on a stainless steel coil or plate. Compared with the stainless steel seamless pipe, there are welds in the manufacturing processing, and still maintain the excellent properties of stainless steel.
Stainless steel pipe type by shape
Stainless steel square pipe
Stainless steel square pipe is a kind of stainless steel product with a square cross-section, which is made by cutting, bending, welding and other processes. In the field of architecture and decoration, it is commonly used to design unique handrails, railings and other structures.
Stainless steel rectangular pipe
Stainless steel rectangular pipe is a kind of steel pipe product with a rectangular cross-section, which is made by cutting, bending, welding and other processes. It is suitable for various fields, such as architecture, decoration, structural engineering and manufacturing.
Stainless steel pipe Applications
1. Piping system: Stainless steel pipe is used for transporting liquids and gasses, such as water supply pipeline, oil pipeline, chemical pipeline and so on.
2. Construction and decoration industry: Stainless steel pipe can be made into handrails, railings, stairs, decorative structures, etc.
3. Machinery manufacturing industry: Stainless steel pipe is used to make pipes and components for mechanical equipment.
4. Food industry: Stainless steel pipe is used for places with high hygiene requirements.
5. Energy field: In the fields of nuclear power and thermal power generation, stainless steel pipe is widely used in pipelines and equipment.
6. Medical equipment: Stainless steel pipe is suitable for making medical equipment, surgical tools, etc.

Quality Assurance
1) How to ensure the quality of stainless steel pipe？The main component of stainless steel pip is iron, by adding such as nickel, chromium and other metal elements. 316 stainless steel has more of a rare metal called molybdenum (Mo) than 304.
2) What does L stand for in the material? Compared with 316, 316L has a lower carbon content of about 0.03%. Therefore, 316L stainless steel is more corrosion resistant, especially in the welding process. Therefore, in the production, we completely produce according to the customer's customized materials, in order to ensure that the needs of customers are met.
3) During the processing of stainless steel pipes, various process parameters such as extrusion, cold drawing and welding need to be strictly controlled. Finished product inspection, especially pay attention to check the processing technology, and welding defects.
4) Qualified stainless steel pipes must first ensure that the surface is smooth and clean, without dents, oxidation and other defects. For some that cannot be detected by the naked eye, all require the use of professional detection tools for detection.
