200/300/400 Series 201/304/316L/409 Stainless Steel Seamless / Welded Pipe /

Product Specification

200/300/400 series 201/304/316L/409 stainless steel Seamless/welded stainless steel pipe / tube

Types of Stainless Steel Pipes/Tubes

Seamless Stainless Steel Pipes/Tubes:

Definition: Made from a solid round steel billet that is heated and pushed or pulled over a form until it becomes a hollow tube. There are no seams or welds.

Advantages:

Strength: Higher pressure ratings and strength due to the absence of welds.

Corrosion Resistance: Uniform structure provides better resistance to corrosion.

Applications: Ideal for high-stress applications such as oil and gas, chemical processing, and high-pressure systems.

Welded Stainless Steel Pipes/Tubes:

Definition: Made by rolling a flat piece of stainless steel into a tube and welding the edges together.

Advantages:

Cost-Effective: Generally less expensive to manufacture than seamless pipes.

Versatility: Available in larger diameters and various wall thicknesses.

Applications: Suitable for low-pressure applications, structural components, and general-purpose use.

Key Grades of Stainless Steel

304:

General-purpose austenitic stainless steel with excellent corrosion resistance and good formability. Commonly used in food processing and kitchen equipment.

316L:

A low-carbon version of 316 stainless steel, offering improved corrosion resistance, especially in chloride environments. Often used in marine and chemical applications.

201:

A cost-effective alternative to 304 with lower nickel content. It provides good corrosion resistance and is often used in kitchen equipment and appliances.

409:

Ferritic stainless steel known for its good oxidation resistance and moderate corrosion resistance, commonly used in automotive exhaust systems.

Applications

Seamless Pipes: Ideal for high-pressure applications in industries such as oil and gas, pharmaceuticals, and power generation.

Welded Pipes: Commonly used in construction, plumbing, and for structural applications where high pressures are not a concern.

Considerations

Corrosion Resistance: Select the appropriate grade based on the specific environment and potential exposure to corrosive substances.

Mechanical Properties: Ensure the pipes/tubes meet the necessary mechanical properties for your application, such as tensile strength and ductility.

Standards and Specifications: Familiarize yourself with standards such as ASTM A312 (for seamless) and ASTM A53 (for welded) for guidance on manufacturing and testing.

Quality Assurance: Choose manufacturers with quality certifications (e.g., ISO) and request material certification to ensure compliance with standards.
