What is the X46 straight seam steel pipe?

X46 straight seam steel pipe is used for double-sided submerged arc welding, and is mainly used for spiral seam welding steel pipe device for pressure-bearing fluid transportation. The steel pipe has strong pressure-bearing ability and good welding performance. After various strict inspections and tests, the use situation is relatively good. The physical diameter of the steel pipe is large, the transportation efficiency is also high, and the investment in laying pipelines can be saved. It is mainly used in pipelines that transport oil and gas.

The API 5L X46 straight seam steel pipe device mainly deforms the steel coil into a smooth cylindrical shape after the hot-rolled coil is formed by the forming machine. The skin effect and proximity effect of the high-frequency current or the arc burning under the flux layer are used for welding operations to promote the heating and melting of the edge of the tube blank, and the fusion is realized under the action of the corresponding extrusion force, and the final cooling is formed. Among them, the edge of the tube is melted by high-frequency current is called high-frequency LSAW pipe, and the one that uses arc melting is called LSAW.
