SAW (Submerged Arc Welded) steel pipe is a type of large-diameter steel pipe that is manufactured using the submerged arc welding process. It is commonly used in various industries, including oil and gas, construction, and infrastructure.
In the SAW process, the welding is performed under a blanket of granular flux, which creates a protective atmosphere around the weld zone. This helps prevent atmospheric contamination and ensures a high-quality weld. The welding is typically done by a continuous wire feed, and the arc is submerged in the flux layer.
SAW steel pipes are known for their strength, durability, and suitability for high-pressure and high-temperature applications. They can be produced in large diameters, making them ideal for transporting fluids and gases over long distances. The pipes have excellent straightness and roundness, providing a consistent flow and minimizing pressure losses.
SAW steel pipes are commonly used in oil and gas pipelines, water pipelines, structural applications, and other industries requiring large-diameter pipes. They offer advantages such as high productivity, good weld quality, and the ability to handle heavy loads and extreme conditions.
It's worth noting that SAW is a broader term that encompasses both longitudinal (LSAW) and spiral (SSAW) submerged arc welding processes. LSAW pipes have a straight seam, while SSAW pipes have a spiral seam. Both types offer unique advantages depending on the specific application.
