Epoxy coal asphalt anticorrosive steel pipe is sprayed with a layer of coal asphalt primer after special treatment on the surface of the steel pipe, and then a layer of epoxy covering layer is sprayed with epoxy resin, and then a layer of polyethylene protective layer is coated. Therefore, epoxy coal asphalt anticorrosive steel pipe has the following advantages:
1.Excellent anti-corrosion performance: The protective layer of coal asphalt primer can prevent oxidation on the surface of the steel pipe, and form a dense protective layer on the surface of the steel pipe, so as to have a better anti-corrosion effect.
2.High wear resistance: After the covering layer of epoxy resin, the surface of the epoxy coal asphalt anticorrosive steel pipe can withstand large friction and wear, thereby prolonging the service life of the steel pipe.
3.Low coefficient of friction: The surface of the epoxy coal asphalt anticorrosive steel pipe is smooth, so the friction coefficient is small, which can improve the efficiency of sewage transportation.
4.Convenient construction: Compared with other anti-corrosion treated steel pipes, epoxy coal asphalt anti-corrosion steel pipes are simple and fast to build, which can effectively save construction costs.
Introduction to epoxy coal asphalt anticorrosive steel pipes:
1. Application of epoxy coal asphalt anticorrosive steel pipe.
Epoxy coal asphalt anticorrosive steel pipes are widely used in sewage treatment pipelines in municipal construction, chemical enterprises, water plants and other fields. Some underground areas that need to discharge sewage, such as underground shopping malls and underground parking lots, will also use epoxy coal asphalt anticorrosive steel pipes. Because these places have relatively high requirements for sewage pipelines, sewage pipelines are required to have good anti-corrosion performance and be able to withstand greater pressure.
2. Inspection of epoxy coal asphalt anticorrosive steel pipe.
In order to ensure the quality of epoxy coal asphalt anticorrosive steel pipes, inspections should be carried out. Including visual inspection and inspection of physical and chemical indicators. During the inspection, it is necessary to find out whether the appearance of the steel pipe is intact, whether there are dents, scratches and deformations, etc., and whether it meets the relevant national standards, whether the physical and chemical indicators meet the specified requirements, etc.
3. Installation of epoxy coal asphalt anticorrosive steel pipe.
When installing epoxy coal asphalt anticorrosive steel pipes, pipelines should be laid first, including pipeline supports, pipeline connectors, pipeline burial, etc. After the laying is completed, a water test should be carried out to confirm that there is no leakage before the sewage patency test is carried out. During the installation process, it is also necessary to pay attention to the details of each link, including end treatment, bolt connection, etc., to ensure the installation quality of the sewage pipeline.
4. Maintenance of epoxy coal asphalt anticorrosive steel pipes.
In order to ensure the normal service life of epoxy coal asphalt anticorrosive steel pipes, regular maintenance is required. Maintenance methods include pipe flushing, anti-corrosion retreatment, and anti-corrosion paint repair. At regular intervals, it is necessary to clean up the dirt and impurities in the pipeline to keep the pipeline unblocked, and at the same time, it is also necessary to recoat the anticorrosive paint to avoid corrosion on the surface of the pipeline due to the influence of external conditions.
