European Standard Stainless Steel Pipes

By Manufacturing Process

Seamless Stainless Steel Pipes

• Production Method: Made from solid billets heated and pierced to form hollow tubes, then processed into pipes without welded seams.
• Standards: EN 10297-2
• Applications: Suitable for high-pressure and high-temperature environments due to their robust construction.

Welded Stainless Steel Pipes

• Production Method: Manufactured by rolling steel plates or strips into cylindrical shapes and welding the seams.
• Standards: EN 10217-7, EN 10312
• Applications: Cost-effective and widely used in various industries for general-purpose applications.

By Material Type

Austenitic Stainless Steel Pipes

• Common Grades: 304, 316, etc.

• Standards: EN 10088-2
• Applications: Commonly used in chemical, food, and pharmaceutical industries.

Ferritic Stainless Steel Pipes

• Common Grades: 430, etc.
• Features: Good corrosion resistance and magnetic properties.
• Standards: EN 10088-2
• Applications: Often used in automotive and decorative applications.

Martensitic Stainless Steel Pipes

• Common Grades: 410, 420, etc.
• Features: High strength and hardness.
• Standards: EN 10088-2
• Applications: Used in cutting tools and industrial equipment requiring high strength.

Duplex Stainless Steel Pipes

• Features: Combine the properties of austenitic and ferritic stainless steels, offering improved strength and corrosion resistance.
