Introduction to European Standard Stainless Steel Welded Pipe Standards

The material standards of European standard stainless steel welded pipes mainly include EN 10217-7 and EN 10312. EN 10217-7 specifies the technical delivery conditions for corrosion-resistant stainless steel welded pipes (round, square and rectangular sections) for general use. EN 10312 refers to the material standards for stainless steel welded pipe systems for drinking water and food industries.

2. Specification standards
The specification standards of European standard stainless steel welded pipes mainly include EN 10217-7 and EN 10312. EN 10217-7 specifies requirements for outer diameter, wall thickness and length, with a maximum outer diameter of 114.3mm and a maximum wall thickness of 3.6mm. EN 10312 specifies the specification requirements for the internal, external and connection parts of the pipe system for pipe systems used in the drinking water and food industries.

3. Size standards
The size standards of European standard stainless steel welded pipes mainly include EN 10217-7 and EN 10312. EN 10217-7 specifies the length and tolerance of stainless steel welded pipes with an outer diameter of 6mm to 114.3mm, and the length is generally about 6 meters. EN 10312 specifies the tolerance of the outer diameter and inner diameter of stainless steel pipes at the connection of the pipeline system to ensure the tightness of the pipeline connection.

4. Application Scope
European standard stainless steel welded pipes are mainly used in chemical, petroleum, natural gas, papermaking, shipbuilding, food, medicine, environmental protection and other industries. Among them, stainless steel welded pipes of EN 10217-7 standard are widely used in petrochemical equipment and petroleum refining industry, while stainless steel welded pipes of EN 10312 standard are used in pipeline systems of drinking water and food industries.
