Description

Technical Field

[0002] Welded steel pipe, also known as welded pipe, is a steel pipe made by welding steel plates or strips after curling and forming. Submerged arc welding refers to a method of arc welding in which the welding arc is covered by flux: the molten metal pool solidifies into a weld under the protection of the flux coating, and the molten layer of the flux cools to form a slag shell covering the outer surface of the weld. Flux is a granular substance that can melt to form slag during welding and has a protective and metallurgical effect on the molten metal. After the welding of the steel pipe is completed, it is generally only necessary to clean up the welding slag and residual flux at the weld position. At present, the residual flux and welding slag at the weld position are treated as waste, which is not friendly to the environment. In addition, the residual flux does not participate in the reaction, its physical and chemical state does not change, and it can continue to be used. Direct disposal causes a waste of resources.
