There are many anti-corrosion treatment methods for water pipes, and the common ones are:
1. Lining coating: Lining coating is a method of coating materials such as polyurethane or epoxy resin inside the pipeline. Forming a sealing layer in the pipeline can prevent the pipeline from being damaged by chemical substances such as oxides produced by corrosion in the water pipe. This treatment method is widely used in chemical industry, petroleum, metallurgy and other industries.
2. External anticorrosive coating: For water pipes exposed to the air, the external anticorrosive coating can protect the pipeline from the corrosion of oxides and corrosive substances in the atmosphere. Common coating materials are polyurethane and epoxy resin.
3. Hot-dip galvanizing: Hot-dip galvanizing is a method of soaking iron products in molten zinc to form a zinc layer on their surfaces, which can form a solid corrosion-free protective layer on the surface of pipelines, improve their comprehensive anti-corrosion ability and anti-corrosion performance, and is widely used in construction, machinery and other fields.
4. Plastic coating of carbon steel: Plastic coating of carbon steel is a method of spraying a layer of plastic material on the surface of steel pipe to form a corrosion-resistant surface layer to protect the water pipe from corrosion and improve its service life. Commonly used plastic materials are polyethylene, polyvinyl chloride and so on.
5. Thickening of the bottom layer: In the production process of water pipes, increasing the thickness of the bottom can reduce the possibility that the bottom is easily damaged by the outside world and improve its service life.
The above are the commonly used anti-corrosion treatment methods for wall water pipes, and the specific choice of which method needs to be determined according to the specific material and use environment of the water pipes. In addition, the installed water pipes should be inspected regularly, and problems should be found and maintained in time to ensure the normal work of the water pipes and prolong their service life.
