Stainless steel is a highly versatile material characterized by its resistance to corrosion and rust.Stainless steel material primarily consists of iron, chromium, and other elements like nickel and molybdenum,has excellent corrosion resistance, high temperature resistant and heat resistance.
Stainless steel pipe is a hollow elongated round steel material, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components.There are many types of stainless steel pipes,usually classified as follows.
1.Production method
According to the production method, stainless steel tubing can be divided into two categories: seamless steel pipes and welded steel pipes.

1)Seamless piping:
hot-rolled pipes, cold-rolled pipes, cold-drawn pipes and extruded pipes, etc. Cold-drawn and cold-rolled pipes are the secondary processing of ss pipes.
2)Stainless Steel Welded Pipe:
A:Classification by Process-Gas Shielded Welded Pipe,Arc Welded Pipe,Resistance Welded Pipe(high frequency,low frequency)
B:Classification by Seams-Straight seam welded pipe (LSAW steel pipe) and spiral welded pipe.

2.Section Shape
Stainless steel pipes can be divided into round pipes and special-shaped tubes according to the cross-sectional shape.
Special-shaped tubes include rectangular tubes, diamond-shaped tubes, oval tubes, hexagonal tubes, octagonal tubes, and various asymmetrical tubes.
3.pipe Wall Thickness
SS Pipe can be divided into thin wall stainless steel tube and thick wall stainless steel tube.

4.Tube End Shape
Stainless steel pipes can be divided into plain pipes and threaded pipes (threaded steel pipes) according to the state of the pipe ends.
5.Material Classification
Stainless Steel is adivided into Austenitic,Ferritic,Martensitic,Duplex stainless steel according to the structure state.
| Austenitic Stainless Steel | 201,301,304/L,305,309/S,310/S,314,316/L/H,321,347,370,etc |
| Ferritic Stainless Steel | 429,430,433,434,435,436,439,etc |
| Martensitic Stainless Steel | 410,414,416,420,431,440A,440B,440C,etc |
| Duplex Stainless Steel | S31803,S32101,S32205,S32304,S32750,etc |
