What is DSAW pipe?
DSAW (Double Submerged Arc Welded) pipes are a type of welded steel pipe known for their robustness and reliability. This manufacturing process involves two welding arcs that create a strong, continuous joint along the pipe's length. The DSAW process is particularly suitable for larger diameter pipes and heavy wall applications, making them ideal for use in high-pressure pipelines, structural applications, and offshore projects.
These pipes are commonly utilized in various industries, including oil and gas, water supply, and construction, due to their excellent mechanical properties and resistance to corrosion. With their enhanced strength and durability, DSAW pipes offer a cost-effective solution for transporting fluids and gases over long distances.
Yuhong group provides high quality DSAW pipe and export to various countries around the world, welcome to contact us for more details.
