Large Diameter Stainless Steel Pipes, Shape : Round

Stainless steel large diameter pipes are robust, corrosion-resistant tubes with a greater outer diameter, commonly used in industries requiring high strength and durability. Here’s a detailed description:

Material Composition:

•Typically made from stainless steel grades such as 304, 304L, 316, 316L, 321, and 347.

•These grades offer excellent resistance to corrosion, oxidation, and high temperatures.

Size Specifications:

•Outer Diameter (OD): Generally ranges from 12 inches (300 mm) to 120 inches (3000 mm) or larger.

•Wall Thickness: Varies from Schedule 5S to Schedule XXS or custom thicknesses.

•Length: Available in standard lengths (e.g., 6m, 12m) or custom lengths as required.

Manufacturing Process:

•Seamless: Made by extrusion, ideal for high-pressure applications.

•Welded (ERW, LSAW, SSAW): Formed by rolling and welding, suitable for lower pressure and larger diameters.

Surface Finish:

•Mill Finish: Standard, non-polished surface.

•Polished Finish: Available in #4, #8 mirror finish for aesthetic or sanitary applications.

•Pickled and Passivated: For enhanced corrosion resistance.

Key Features:

•Corrosion Resistance: Suitable for harsh environments (e.g., marine, chemical, and petrochemical industries).

•Strength and Durability: High mechanical strength and pressure resistance.

•Hygienic Properties: Ideal for food and pharmaceutical applications due to easy cleaning.

Applications:

•Oil and Gas Industry: For transporting oil, gas, and petrochemicals.

•Construction: Structural supports, bridges, and infrastructure.

•Water Treatment: Desalination and wastewater systems.

•Food Processing: Hygienic transport of liquids.

• Power Plants: For steam and fluid conveyance under high temperatures and pressure.
