Spiral steel pipe is a spiral seam steel pipe made of strip steel coil as raw material, extruded at regular temperature, and welded by automatic double-wire double-sided submerged arc welding. Spiral steel pipes are made by double-sided automatic submerged arc welding and are used for transporting general low-pressure fluids such as water, gas, air, and steam. Double-wire and double-sided submerged arc welded spiral steel pipes are made by arcing under the flux layer. The welding method uses the heat generated by the arc burning under the flux layer between the welding wire and the flux to melt the welding wire flux and the base metal. The main features of this product are: first, double-sided submerged arc welding, which not only has a high deposition rate, but also has deep penetration capabilities; second, the arc and welding zone are well protected, the weld quality is excellent, the density is good, and the weld appearance is smooth , smooth, and can meet various performance requirements for welds. Submerged arc welded steel pipes for general low-pressure liquid transportation are made by double-sided automatic submerged arc welding or single-sided welding. They are used to convey general low-pressure fluids such as water, gas, air, oil, and heating steam and welded steel pipes for other purposes. In addition to being directly used to transport fluids, welded steel pipes for low-pressure fluid transportation are also used as the original pipes for galvanized welded steel pipes for low-pressure fluid transportation.

Use of pipe
Double-sided submerged arc welding Spiral steel pipes are mainly used in water supply projects, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, and urban construction. Used for water supply and drainage for liquid transportation. For gas transportation, coal gas, steam, and liquefied petroleum gas are used. It is used as piling pipes for structures, pipes for bridges, wharves, roads, building structures, etc.
Main process features of spiral steel pipe
. During the forming process, the steel plate deforms evenly, has small residual stress, and does not produce scratches on the surface. The processed spiral steel pipe has greater flexibility in the size range of diameter and wall thickness, especially in the production of high-grade thick-walled pipes, especially small and medium-diameter thick-walled pipes, which can meet the user's specifications of spiral steel pipes. More requests.
. Adopting advanced double-sided submerged arc welding technology, welding can be achieved at the right position, and defects such as misalignment, welding deflection and incomplete penetration are not prone to occur, and the welding quality is easy to control.
. Conduct comprehensive quality inspections on steel pipes so that the entire process of steel pipe production is under effective inspection, effectively ensuring product quality.
. All equipment in the entire production line has the function of networking with the computer data collection system to realize real-time transmission of data, and the central control room monitors the technical parameters in the production process.
