ASTM API 5L X52/X56/60 LSAW Steel Pipe Submerged Arc Welded Steel Pipe
The production process of double-sided submerged arc welded (SAW) steel pipes involves several key steps to ensure high-quality and efficient manufacturing:
Material Preparation: The process begins with the selection of high-quality steel coils or plates. These materials are inspected for defects and then sheared or leveled to the required dimensions.
Edge Milling: The edges of the steel plates or coils are milled to achieve a precise angle and smooth surface finish, ensuring proper alignment during welding.
Edge Preparing: Prior to welding, the edges of the steel plates or coils are beveled to the required angle and shape. This beveling process ensures proper penetration and fusion of the weld seam.

Submerged arc welded (SAW) steel pipe, commonly known as submerged arc welded pipe, is a type of welded steel pipe manufactured using the submerged arc welding process. This welding method involves the formation of a welded joint between the edges of a steel plate or coil strip, while the welding arc is submerged beneath a layer of granular flux. The flux serves multiple purposes, including shielding the arc, stabilizing the molten weld pool, and facilitating the removal of impurities.
SAW steel pipes find extensive applications across various industries due to their numerous advantageous properties:
High Strength: SAW steel pipes possess high tensile strength and toughness, making them suitable for applications requiring structural integrity and durability.
