Stainless steel pipes, also called stainless steel tubes.
If you are the beginner of this area, you will be an expert through this guide.
The proportion of the nickel and chromium added is different, and the mechanical properties and application fields of the stainless steel pipes produced are different.
It is mainly manifested in the following 10 aspects.
Stainless Steel Pipes Standards
The stainless steels pipe can be of the GB, ASTM, JIS, GOST, and DIN production standards, etc.
Usually the ASTM is the common standard in global market. If you come from Russia, you should consider to GOST standard to order your pipes and tubes cargo.

Stainless Steel Pipes Grades
Common use stainless steel pipes grades are often represented by digital symbols.
According to the metallographic structure of stainless steel, it can be divided into semi-ferritic and semi-martensitic stainless steel pipes, martensitic stainless steel pipes, austenitic stainless steel pipes, austenitic-ferritic stainless steel pipes, etc.
Before sending us the inquiry of stainless steel pipes, you should indicate the detailed grade of them.
Types of Stainless Steel Pipes
According to the types, stainless steel pipe is divided into seamless stainless steel pipe and welded stainless steel pipe.
Stainless steel seamless pipes are long strip of steel with a hollow section and no welding seams around it.
The thicker the wall thickness of the stainless steel seamless pipe, the more economical and practical it is, and the thinner the wall thickness is, the higher its processing cost will be.
Stainless steel welded pipes, referred to as welded pipes, they are steel pipes made of commonly used stainless steel strips or plates after being crimped and formed by a unit and a mold.
Wall Thickness of Stainless Steel Pipes
Wall thickness is from 0.022mm to 30.0mm or according to customer’s requirement.
Stainless Steel Pipes Outer Diameter
Outer diameter is from 0.1mm to 1300mm or according to customer’s requirement.
Stainless Steel Pipes Production Tolerance
The outer diameter tolerance of high finish is ±0.05mm, the wall thickness tolerance can also reach ±0.03mm, and the inner hole size tolerance is strictly controlled, which can reach between 0.02mm to 0.05mm.
The inner and outer surface finish is Ra 0.8μm after polishing, the inner and outer surface finish of the tube can reach Ra 0.2—0.4μm. If the customer has the special precision surface finish required, it can even reach below Ra0.1μm or even 8K mirror surface.
Stainless Steel Pipes Length
Length is from 0.3 meters to 15.8 meters or as customer’s requirement.
Stainless Steel Pipes Surface Finish
Through different processing methods of cold rolling and surface reprocessing after hot-extruded or cold drawn, the surface finish of stainless steel pipe can have different types.
Polishing, Annealing, Mirror surface, Bright, Pickling and Other finishes are available as customers’ request.
HZW provides a wide range of surface finishing services for a wide range of stainless steel pipes. Such as: polishing, painting, brushing, logo printing, etc.
