Double Submerged Arc Welded (DSAW) pipe is a premium steel pipe manufactured using an advanced welding process that ensures superior strength, durability, and reliability for high-pressure applications. The DSAW process involves forming steel plates into a cylindrical shape and welding both the inside and outside seams using submerged arc welding (SAW), resulting in a robust, uniform weld with excellent mechanical properties. Manufactured to API 5L, ASTM A252, EN 10219, and other international specifications to ensure quality and performance. DSAW pipe delivers unmatched reliability for critical infrastructure projects, combining advanced welding technology with high-grade steel for long-term performance.
1.Exceptional Strength & Durability: The double-sided welding process enhances structural integrity, making DSAW pipes ideal for high-pressure oil, gas, and water transmission systems.
2.Large Diameter Capability: Available in diameters ranging from 16" to over 100", DSAW pipes are perfect for major pipeline projects requiring wide-bore conduits.
3.Smooth Weld Seam: The submerged arc welding technique produces clean, defect-free welds with minimal internal roughness, improving flow efficiency.
4.Corrosion Resistance: Can be coated or lined for additional protection in corrosive environments, extending service life.
5.Versatile Applications: Suitable for onshore and offshore pipelines, structural piling, and industrial fluid transport.
