321 Stainless Steel Pipe
What are the introduction and uses of 321 stainless steel pipes?
Stainless steel pipeis a kind of hollow long round steel, mainly used in petroleum, chemical, medical, food, light industry, mechanical instrumentation, and other industrial transmission pipelines and mechanical structural components. In addition, when the bending and the torsional strength are the same, the weight is light, so it is also widely used for manufacturing mechanical parts and engineering structures. Also commonly used as furniture and other kitchen utensils.
Stainless steel pipes are available in a wide range of connections. Common types of pipes include compression, compression, union, push, push screw, socket weld, live flange, welded and welded, and conventional connections. Combined derived series connection. These connection methods, based on their different principles, have different application scopes, but most of them are easy to install, solid, and reliable. Most of the sealing rings or gasket materials used in the connection are silicone rubber, nitrile rubber, and EPDM rubber that meet the requirements of national standards, eliminating the user's worries.
What are the classifications of ?
The stainless steel pipes are divided into ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, stainless steel pipes, and bimetallic composite pipes, coatings, and coated pipes to save precious metals and meet special requirements. Stainless steel pipes have a wide range of types and different uses. Their technical requirements are different, and production methods are also different. The current production of steel pipe diameter range of 0.1-4500mm, wall thickness range of 0.01-250mm. In order to distinguish its characteristics, the steel pipes are generally classified as follows.
- , cold-rolled pipes, cold-drawn pipes, and extruded pipes. Cold-drawing and cold-rolling are secondary steel pipes. Processing; welded pipe is divided into straight seam welded pipe and spiral welded pipe.
- can be divided into round tubes and shaped tubes according to the cross-sectional shape. Special-shaped tubes include rectangular tubes, diamond tubes, elliptical tubes, hexagonal tubes, octane tubes, and various cross-section asymmetric tubes. Shaped tubes are widely used in various structural components, tools, and mechanical components. Compared with a round pipe, a special-shaped pipe generally has a larger moment of inertia and section modulus, and it has greater resistance to bending and torsion, which can greatly reduce the structural weight and save steel.

What is the performance of stainless steel pipe？
Welding performance: All standard welding methods can be used for welding. Welding can be based on the use of 316Cb, 316L, or 309Cb stainless steel filler rods or electrodes for welding. In order to obtain the best corrosion resistance, the welded section of needs post-weld annealing. If 316L stainless steel is used, post-weld annealing is not required.
Corrosion resistance: In this regard, the total performance of 316 steel is better than that of 310 and 304 stainless steel. Under high-temperature conditions, 316 stainless steel has a wide range of uses when the concentration of sulfuric acid is lower than 15% and higher than 85%. And the paper production process has good corrosion resistance.
