　　Epoxy powder anti-corrosion steel pipes are coated uniformly and densely on the surface of rust removed metal pipes to isolate them from various corrosive media, which is one of the basic methods for pipeline anti-corrosion. Since the 1970s, more requirements have been put forward for coating performance in harsh environments such as polar regions and oceans, as well as in oil heating and transportation that cause pipeline temperature rise. Therefore, pipeline anti-corrosion coatings are increasingly using composite materials or composite structures.

　　1. External anti-corrosion coating: Types and usage conditions of pipeline external wall coating materials.

　　② Inner wall anti-corrosion coating: a thin film applied to the inner wall of a pipe to prevent corrosion, reduce frictional resistance, and increase throughput. The commonly used coatings include amine cured epoxy resin and polyamide epoxy resin, with a coating thickness of 0.038-0.2 millimeters. To ensure a strong bond between the coating and the pipe wall, it is necessary to perform surface treatment on the inner wall of the pipe. Since the 1970s, there has been a trend towards using the same material for the coating of both the inner and outer walls of pipes, in order to achieve simultaneous coating.

　　③ Anti corrosion and thermal insulation coating: A composite layer of insulation and anti-corrosion is added to the outside of pipelines with medium and small diameters for transporting crude oil or fuel oil, in order to reduce heat dissipation from the pipeline to the soil. The commonly used thermal insulation material is rigid polyurethane foam, and the applicable temperature is -185~95 ℃. This material has a soft texture. To improve its strength, a high-density polyethylene layer is added outside the insulation layer to form a composite structure to prevent groundwater from seeping into the insulation layer.

　　Fusion bonded epoxy powder coating is a new type of anti-corrosion coating developed in the past 30 years, which uses electrostatic spraying technology to apply epoxy powder coating and form a film in one go. This coating has the characteristics of simple coating operation, no pollution, good impact and bending resistance, and high temperature resistance.

　　Application of single-layer epoxy powder anti-corrosion steel pipe: The product is widely used in oil pipelines, natural gas pipelines, heating pipelines, and water supply pipelines.

　　With the development of the economy and the increasing demand for quality of life, people's requirements for water quality are becoming more stringent, and there is also a growing emphasis on sewage treatment and water recycling. Salts and some chemicals in water can corrode steel, concrete lining, and PCCP concrete pipes. When CO32-, SO42- plasma, and dissolved oxygen penetrate the surface of steel, the steel is oxidized, and the volume expansion of corrosion products causes concrete to rupture, leading to corrosion of steel pipes and cast pipes, rupture of concrete pipes, and pollution of water quality.

　　To prevent corrosion, anti-corrosion coatings can be applied to the inner walls of steel and concrete pipes for protection. Currently, the commonly used internal anti-corrosion materials at home and abroad mainly include epoxy resin and polyurethane resin coatings.

　　Epoxy resin coatings have particularly good salt alkali resistance and can adhere to the alkaline surface of concrete layers for a long time. They are anti-corrosion and anti-seepage coatings on the surface of concrete layers. The company once applied epoxy paint to concrete test blocks and soaked them in saturated salt water for 23 years. It still has a bright appearance, strong bonding, and maintains toughness to this day.

　　Execution standards: SY/T0315-97, SY/T0315-2005, CAN/CSA-Z245.20-M98, DIN30671, Q/CNPC38-2002.
