Application field of spiral steel pipe for sewage discharge

Application field of spiral steel pipe for sewage discharge Spiral pipe is made by rolling low-carbon carbon structural steel or low alloy structural steel strip into a tube blank according to a certain helical angle (called forming angle), and then welding the pipe seam. It can be made with a narrower strip Steel produces large diameter steel pipes. Its specifications are expressed by outer diameter * wall thickness. The welded pipe should ensure that the hydraulic test, the tensile strength of the weld and the cold bending performance must meet the regulations. Inspection process: Raw material inspection—leveling inspection—butt welding inspection—formation inspection—inner welding inspection—outer welding inspection—pipe cutting inspection—ultrasonic inspection—groove inspection—outline dimension inspection—X-ray inspection –Hydraulic test –Final inspection In order to guarantee the products, we have formulated a comprehensive plan, on-site work procedures and inspection and test plans. Application examples of spiral steel pipes for sewage discharge: 1. In agricultural engineering, spiral steel pipes for sewage pipes also play a certain role. Irrigation pipes, deep well pipes, drainage pipes, etc., help farmers save a lot of effort. 2. In the process of transporting oil, the spiral welded steel pipe of the sewage pipeline is used as a transportation pipeline. 3. Spiral steel pipes for sewage discharge are used in coal mines, power plants, sewage treatment, fire protection, petroleum, municipal engineering, chemicals, and highway products. 4. In urban construction, spiral welded steel pipes for sewage pipes are used for high-rise building water supply, heating network heating, tap water engineering, gas transportation, buried water transportation, etc., making a lot of contributions to municipal construction. 5. In coal mine engineering, the spiral welded steel pipe for sewage pipes mainly plays the role of underground coal mine water supply and drainage, underground spraying, positive and negative pressure ventilation, gas drainage, fire sprinkler and other pipe networks. 6. In power plants, spiral welded steel pipes for sewage pipes are mainly used as pipelines for process water waste residue and return water in thermal power plants. Spiral steel pipes for sewage discharge can be treated with anti-corrosion treatment according to customer needs, so as to increase the service life of the pipe body and save the cost of the enterprise.
