1. The epoxy coal asphalt anti-corrosion steel pipe is coated with a layer of epoxy powder coating on the surface of the black pipeline steel pipe, and then the evenly stirred coal asphalt oil is applied to the coating, and after heating, it is cross-linked with the surface of the steel pipe to form a layer of epoxy coal asphalt anti-corrosion layer with a thickness of no more than 500 m.
2. This layer of coating not only has corrosion resistance and chemical stability, but also can effectively resist the corrosion of different types of chemicals, such as acids, alkalis, salts, etc. Due to its anti-corrosion effect, epoxy coal asphalt anti-corrosion steel pipe has gradually replaced the traditional anti-corrosion measures, such as dyeing, galvanizing, etc., and has become the mainstream anti-corrosion material in the construction and maintenance of sewage pipelines.
3. There are many other advantages to the use of epoxy coal asphalt anticorrosive steel pipes. For example, fast installation, easy maintenance, high safety, etc. It is precisely because of these advantages that epoxy coal asphalt anticorrosive steel pipes have gradually become a material for the construction and maintenance of urban sewage pipelines.
What are the advantages of three cloth and four oil anti-corrosion steel pipes for drinking water
1. The anti-corrosion steel pipe with three cloths and four oils for drinking water does not contain harmful substances such as lead, chromium and cadmium.
These harmful substances are difficult to avoid in conventional steel pipe materials. However, in the manufacturing process of three cloth and four oil anti-corrosion steel pipes for drinking water, special technical treatment has been adopted to meet the national environmental protection standards, as well as the limit regulations of lead, cadmium and other substances. In terms of safety, you can use it with complete peace of mind.
2. The three-cloth and four-oil anti-corrosion steel pipe for drinking water has excellent corrosion resistance.
In several years or even ten years of use, there is no obvious sign of corrosion on its surface, and long-term use has no impact on the safety of drinking water. The steel pipe with three cloth and four oil anti-corrosion technology for drinking water has met the requirements in various indicators such as thickness, coating uniformity, adhesion and flexibility, and fully meets the sanitary requirements and safety standards of drinking water.
3. The anti-corrosion steel pipe with three cloths and four oils for drinking water has good high temperature resistance.
In a high-temperature environment, the general steel pipe will be deformed and aged, while the three-cloth and four-oil anti-corrosion steel pipe for drinking water will not. Because of the special hardening treatment in the manufacturing process of steel pipes, it has good high-temperature performance and can adapt to various harsh environmental conditions in engineering.
4. The three-cloth and four-oil anti-corrosion steel pipe for drinking water has high pressure resistance.
In the application, it is subjected to a variety of external forces such as pressure and torque, so the performance requirements for the strength and hardness of the steel pipe are relatively high. The raw materials of the three-cloth and four-oil anticorrosive steel pipe for drinking water have been refined and heat treated by the steel mill, so that the physical structure of the steel pipe is uniform and there are no obvious internal defects, so as to ensure that the steel pipe has high pressure resistance.
