. Application examples of spiral steel pipes for sewage discharge
In agricultural engineering, spiral welded steel pipes for sewage pipes also play a certain role Functions, irrigation pipes, deep well pipes, drainage pipes, etc., help farmers save a lot of effort.
In the process of transporting oil, the spiral welded steel pipe of the sewage pipeline is used as a transportation pipeline.
Spiral steel pipes for sewage discharge are used in coal mines, power plants, sewage treatment, fire protection, petroleum, municipal engineering, chemical industry, and highways.
In urban construction, spiral welded steel pipes for sewage pipes are used in high-rise building water supply, heat network heating, tap water projects, gas transportation, underground water transportation, etc., making a lot of contributions to municipal construction.
In coal mine engineering, spiral welded steel pipes for sewage pipes mainly serve as pipe networks for underground coal mine water supply and drainage, underground grouting, positive and negative pressure ventilation, gas drainage, fire sprinkler and other pipe networks.
In power plants, spiral welded steel pipes for sewage pipes are mainly used as process water waste and return water transport pipes in thermal power plants.
. Spiral steel pipes for sewage discharge can be anti-corrosion treated according to customer needs. Increase the service life of the pipe body. Save business costs.
.Tool rust removal
. First use tools such as wire brushes to polish the surface of the steel to remove loose or lifted oxide scale, rust, welding slag, etc. The rust removal of manual tools can reach grade 1, and the rust removal of power tools can reach grade 1. If strong iron oxide scale is attached to the surface of the steel, the rust removal effect of the tools will not be satisfactory, and the anchor pattern depth pickling required for anti-corrosion construction will not be achieved
. Acid Washing and rust removal
. Chemical and electrolytic methods are usually used for pickling treatment. Only chemical pickling is used for pipeline anti-corrosion, which can remove scale, rust, and old coatings. Sometimes it can be used as a cleaning agent after sand blasting and rust removal. Process again. Although chemical cleaning can make the surface reach a certain degree of cleanliness and roughness, its anchor lines are shallow and it can easily pollute the environment
.Spray (throwing) rust removal
.In order to obtain better uniform cleanliness and roughness distribution, the appropriate particle size and proportioning plan of the abrasive is important. Too much roughness will easily cause the anti-corrosion layer to become thinner at the peaks of the anchor lines. At the same time, because the anchor lines are too deep, bubbles will easily form in the anti-corrosion layer during the anti-corrosion process, seriously affecting the performance of the anti-corrosion layer.
