This product is a large-diameter anti-corrosion steel pipe newly developed by Huaqi Company, and its executive standard is GB T97111. It is mainly used for long-distance transportation pipelines such as oil, natural gas, gas and water.
First of all, let's understand the principle of anti-corrosion of this product. 457.The 2mm anti-corrosion water supply welded steel pipe adopts a three-layer structure to prevent corrosion, including an epoxy powder layer, an adhesive layer and a polyethylene layer. This anti-corrosion structure can effectively prevent the inner and outer surfaces of the steel pipe from being corroded, and prolong the service life of the steel pipe.
Secondly, the main technical parameters of the product include the diameter, length, wall thickness, material, etc. of the steel pipe. Among them, the diameter of the steel pipe is 4572mm, the length can be customized according to user needs, the wall thickness is calculated according to the design pressure and pipe diameter, and the material is Q235B. In addition, the welding method of this product is manual arc welding, and the weld shape is a straight seam.
In the making, 4572mm anti-corrosion water supply welded steel pipes need to undergo strict raw material inspection, groove processing, nozzle cleaning, internal and external weld bead grinding and other processes. Among them, the groove processing adopts cutting, grinding and other methods, the nozzle cleaning uses wire brushes, grinders and other tools, and the internal and external weld bead grinding adopts manual grinding or machine grinding.
Finally, let's take a look at the range of applications for this product. 457.2mm anti-corrosion water supply welded steel pipe is mainly used for long-distance transmission pipelines such as oil, natural gas, gas, water, etc., and can also be used for anti-corrosion protection in large steel structures, bridges, buildings and other fields. In addition, due to its excellent anti-corrosion performance and durability, the product is also suitable for marine engineering, chemical industry, electric power and other fields.
In short, 4572mm anti-corrosion water supply welded steel pipe is a kind of large-diameter steel pipe with excellent anti-corrosion performance and wide application. Its three-layer structure anti-corrosion can effectively prevent the steel pipe from being corroded and prolong the service life of the steel pipe. At the same time, the production process of the product is strict, and after multiple processes of processing and processing, its quality and reliability can be guaranteed. Therefore, this product is an ideal anti-corrosion protection material that can meet the needs of different fields.
