The Basic Concept of 316 Stainless Steel Pipes

 

316 stainless steel pipe is a nickel-molybdenum alloy stainless steel pipe with excellent corrosion resistance and high temperature resistance. It is widely used in chemical, petroleum, medicine, food and other fields. Its chemical composition includes nickel, molybdenum, chromium and other elements, which can resist corrosion from corrosive media such as acid and alkali, so it is called "acid-resistant stainless steel pipe".

 

316 stainless steel pipes are usually divided into two types: welded pipes and seamless pipes. Different types of pipes have different outer diameters, wall thicknesses, lengths and other dimensions. For example, the outer diameter of 316 stainless steel welded pipes ranges from 6mm-530mm, and the wall thickness ranges from 0.5mm-45mm.

 

316 stainless steel pipes size table

 

For different types of 316 stainless steel pipes, the specific size table will also be different. The following is the size table of 316 stainless steel welded pipe:

Outer diameter (mm) Wall thickness (mm) Length (mm)

6-159 0.5-20 ≤18000

159-2600 4-45 ≤18000

The above size table is for reference only, the specific size depends on the application field and specific needs.

 

Specifications and models of 316 stainless steel pipes

 

The specifications of 316 stainless steel pipes are a series of codes composed of factors such as size, pipe type, surface treatment, etc. The following are some common specifications of 316 stainless steel pipes:

 

316L-TP316L-SMLS-10S-6M

316L-TP316L-WELD-10S-3M

316L-TP316L-SMLS-40S-4M

316L-TP316L-WELD-80S-5M

 

In the above codes, "L" stands for low carbon content, "TP" stands for pipe material, "SMLS" stands for seamless pipe, "WELD" stands for welded pipe, "10S, 40S, 80S" stands for thickness grade, and "6M, 4M, 5M" stands for length grade.

Processing of 316 stainless steel pipes


1. Heat treatment: According to different alloy compositions and actual application requirements, appropriate heat treatment methods are used to improve the mechanical properties of 316 stainless steel pipes.

2. Cold processing: Put 316 stainless steel pipes into cold machines or other cold treatment equipment for cold processing, which is often used to manufacture precision parts and high-tech products.

3. Machining: Use turning, drilling, milling and other machining methods to process 316 stainless steel pipes into the required shape and size.

 

Application areas of 316 stainless steel pipes

 

316 stainless steel pipe has good corrosion resistance and high temperature resistance, and is widely used in the following fields:

1. Chemical industry: used for pipelines in the oil, natural gas, fertilizer and other industries.

2. Petroleum industry: used for oil well engineering, oil and natural gas pipelines, etc.

3. Pharmaceutical industry: used for pharmaceutical equipment and drug pipelines.

4. Food industry: used for food processing equipment and food pipelines.
