Discover the Advantages of Double Submerged Arc Welded Steel Pipes

In the field of construction and engineering, the integrity and reliability of materials are of utmost importance. We are well aware that a solid foundation is the cornerstone of a project's success. Therefore, we have introduced high-quality ASTM A252 grade steel pipes manufactured using the double submerged arc welding  process, aiming to meet the highest standards for demanding engineering applications.
Product Core: Robust and durable engineering pillars
Our DSAW steel pipes are specifically designed to bear the most critical loads. They are perfectly suitable for:
Foundation piles and bridge piles: Provide a stable and reliable supporting structure.
Pier piles and port structure: Resisting harsh marine environments and ensuring long-term durability.
Various large-scale engineering structures: Provide the core framework for heavy infrastructure construction.
Exquisite Craftsmanship: Double-sided Submerged Arc Welding and Spiral Submerged Arc Welding Technology
The excellence of our products stems from our advanced manufacturing techniques. The double-sided submerged arc welding process enables us to:

Full thickness weld penetration: Ensure that the weld strength is equivalent to that of the base material and eliminate any internal defects.
Outstanding structural integrity: The welds are uniform and dense, significantly enhancing fatigue resistance and impact resistance.
Higher pressure-bearing capacity: Suitable for critical infrastructure where safety factors are extremely demanding.
Furthermore, when producing large-diameter pipes, we also employ the Helical Submerged Arc Welding technology. This process, through continuous spiral welding, enables the efficient production of pipes with larger diameters and more flexible lengths, while maintaining the uniformity and high strength of the welds, providing an ideal solution for specific engineering requirements.
