Spiral steel pipe is a type of steel that is produced by crimping the strip and forming it through a spiral-shaped former, followed by welding and cooling. This kind of steel pipe is mainly used in construction, water conservancy, electric power, petroleum, chemical industry and other fields, as a fluid transportation pipeline, structural support and pressure vessel and other purposes.
The production process of spiral steel pipe includes the following steps: first, the strip is coiled into a spiral shape, then it is formed and welded, and finally it is cooled and inspected. The forming process includes two steps: internal welding, which is to coil the strip into a spiral shape and fix it, and external welding, which is to weld the formed spiral steel pipe. Cooling is required after the welding is completed, either by natural cooling or forced cooling. Finally, a quality check is carried out to ensure that the quality of the steel pipe meets the requirements.
Spiral steel pipes are characterized by high strength, good pressure resistance, strong corrosion resistance, and long service life. In the field of construction, spiral steel pipes are widely used in the construction of high-rise buildings, bridges, highways and other projects as structural support and fluid transportation pipelines. In the field of water conservancy, spiral steel pipes are used in the construction of water pipelines, pumping stations, water treatment facilities, etc. In the field of electric power, spiral steel pipes are used in the construction of thermal power plants, nuclear power plants and other projects, as high-temperature and high-pressure pipelines and structural supports.
In addition to construction, water conservancy, electric power and other fields, spiral steel pipes are also widely used in petroleum, chemical and other fields. For example, in the petroleum field, spiral steel pipes are used in the construction of oil pipelines and oil and gas field exploitation facilitiesIn the chemical industry, spiral steel pipes are used for the transportation of chemical media, reaction devices, etc. Spiral steel pipe manufacturer
