Product Introduction: Spiral welded tube is a type of steel pipe made by spirally winding steel strips or steel plates and welding along the spiral seam. Due to its unique manufacturing process, spiral welded tubes have excellent strength, flexibility, and pressure resistance, making them widely used in oil, natural gas, water supply, drainage, and structural engineering.

Product Features:

1. High Strength: Spiral welded tubes use high-quality steel and undergo strict welding processes, providing high strength and pressure resistance.
2. Corrosion Resistance: The surface can be galvanized, coated, or treated with other anti-corrosion methods to enhance its resistance to harsh environments.
3. Flexible Dimensions: Diameter and wall thickness can be adjusted according to customer requirements, meeting various engineering needs.
4. Cost-Effective: Compared to straight seam welded pipes, spiral welded tubes have higher production efficiency and lower costs, offering a better cost-performance ratio.
5. Reliable Welding Performance: Automated welding equipment and techniques ensure high weld quality, guaranteeing the pipe's sealing and safety.

Technical Specifications:

• Material: Carbon steel, stainless steel, etc.
• Diameter Range: DN100-DN3000
• Wall Thickness Range: 3mm-25mm
• Length: Typically 6 meters or 12 meters, customizable according to customer needs
• Standards: Compliant with international standards such as API 5L, ASTM A252, EN10219, GB/T 9711, etc.

Application Fields:

1. Oil and Gas Transportation: Used for long-distance oil and gas pipelines, providing good pressure resistance and sealing.
2. Water Supply and Drainage Projects: Widely used in urban water supply networks and drainage systems.
3. Structural Engineering: Used as structural support in bridges, piers, roads, and building construction.
4. Other Industrial Applications: Fluid transportation and structural support in industries such as chemical, power, and metallurgy.

Production Process:

1. Raw Material Preparation: Select steel strips or plates that meet the standards.
2. Forming: Spiral the steel strips or plates through a forming machine.
3. Welding: Use automated welding equipment for spiral seam welding, ensuring weld quality and sealing.
4. Inspection: Conduct non-destructive testing such as ultrasonic and X-ray inspections to ensure the quality of the welded tube meets standard requirements.
5. Anti-Corrosion Treatment: Perform galvanizing, coating, or other anti-corrosion treatments as per customer requirements.
6. Finished Product: Cut to specified lengths, package, and transport.

Spiral welded tubes, with their excellent performance and wide range of applications, have become an indispensable important material in modern engineering.
