External Internal Epoxy Anti-Corrosion Steel Pipe
Welded Steel Pipe Supplier-GNEE
The internal and external epoxy powder anti-corrosion steel pipe is a coating with powder plastic as the main body, and its performance is basically determined by the performance of the main plastic. Plastics can be divided into two categories: thermoplastics and thermosetting plastics according to their properties after heating. Thermoplastics are generally made from polymer resin as the basic component, with a small amount of stabilizer, lubricant or plasticizer added (or not added). The characteristics of this type of plastic are that it softens after heating, has plasticity, and can be molded repeatedly. In general, thermoplastics have excellent chemical resistance, toughness and extensibility.

- Application areas
Internal and external epoxy anti-corrosion steel pipes are widely used in petroleum, chemical industry, natural gas and urban water supply.
In the petroleum and chemical industries, internal and external epoxy anti-corrosion steel pipes are used to transport corrosive media, such as acidic, alkaline and high-temperature liquids.
In the field of natural gas and urban water supply, internal and external epoxy anti-corrosion steel pipes are used to transport high-pressure gas and water supply.
Due to its excellent corrosion resistance and long life, internal and external epoxy anti-corrosion steel pipes have been widely used and recognized in these fields.
- Manufacturing
The manufacture of internal and external epoxy anti-corrosion steel pipe mainly includes pretreatment, coating, curing and quality inspection.
The pretreatment stage mainly involves descaling and cleaning the steel pipe to ensure the adhesion of the anticorrosion layer.
The coating stage adopts the coating machine to evenly coat the epoxy resin on the internal and external surfaces of the steel pipe.
Curing stage makes the epoxy resin solidify into a film by heating to form a solid anticorrosion layer.
Quality inspection stage carries out quality inspection on the manufactured internal and external epoxy anti-corrosion steel pipe to ensure that the product meets the relevant standards and requirements.
