Introduction du produit
Our stainless steel seamless pipes are manufactured using state-of-the-art extrusion and cold-drawing processes, ensuring superior strength, uniformity, and reliability. These pipes are ideal for high-pressure and high-temperature applications.
Key Specifications
Diameter: 1/2 inch to 24 inches (21.34 mm to 609.6 mm)
Wall Thickness: 0.5 mm to 50 mm
Standards: ASTM A312, ASTM A213, EN 10216-5, JIS G3459
Material: 304/304L, 316/316L, 321, 310S, 904L, Duplex 2205
Production Process
Billet Preparation: High-quality stainless steel billets are heated to a high temperature.
Extrusion: The billet is extruded through a die to form a hollow shell.
Cold Drawing: The pipe is further processed through cold drawing to achieve precise dimensions and surface finish.
Heat Treatment: Solution annealing is performed to restore microstructure and enhance properties.
Inspection: The pipes undergo rigorous testing, including ultrasonic and hydrostatic tests, to ensure quality.
Applications
Oil and gas exploration and refining
Power generation (boiler and heat exchanger tubes)
Pharmaceutical and biotechnology industries
High-pressure hydraulic systems
Nuclear and thermal power plants
Advantages
High Strength: No welded seams, making them stronger and more reliable for high-pressure applications.
Uniformity: Consistent wall thickness and smooth interior surface.
High-Temperature Resistance: Suitable for extreme temperature conditions.
Corrosion Resistance: Excellent performance in corrosive environments.
