Epoxy coal tar coated spiral steel pipes, commonly referred to as "X-bands Y-oils," include types such as 1-band 2-oils, 3-bands 2-oils, 5-bands 3-oils, and 7-bands 4-oils. The components consist of an epoxy coal tar primer and topcoat, both primarily made of epoxy resin and coal tar, with various rust-proof pigments, insulating fillers, toughening agents, leveling agents, thinners, anti-settling agents, and more. Appearance: the primer's A component is iron red, the B component is black, and the topcoat is all black. They offer excellent resistance to chemical medium corrosion and good physical and mechanical properties, strong adhesion, tough film, and superior electrical insulation and anti-permeability, as well as resistance to stray currents and microbial侵蚀. After curing, they can reduce the number of application coats. The main execution standards are SY/T 0447-96 "Technical Standard for Epoxy Coal Tar Coating on Buried Steel Pipes" and SY/T 0457-2000 "Technical Standard for Internal Liquid Epoxy Coating on Steel Pipes." They are mainly used for the external anti-corrosion of buried or underwater steel pipelines for oil, gas, water supply, and heating, and are also suitable for anti-corrosion of various steel structures, docks, ships, sluices, gas storage tanks, equipment in oil refining and chemical plants, as well as waterproofing and anti-seepage for concrete structures like concrete pipes, sewage pools, roof waterproofing layers, bathrooms, basements, etc. Epoxy coal tar anti-corrosion coatings are composed of two main components: epoxy and coal tar, forming a two-component (A-epoxy, B-curing agent) coating. They have good adhesion, toughness, resistance to moisture, water, and chemicals, can prevent various ions from passing through the coating, and have the property of expanding and contracting with the coated object. The film never peels off or cracks. Thickness: 0.5-1.0mm. Epoxy coal tar is a cost-effective anti-corrosion method, and engineering measurements show that with additional protection, pipelines using epoxy coal tar have shown minimal corrosion after twenty years of use.
Composition: The components consist of an epoxy coal tar primer and topcoat, both primarily composed of epoxy resin and coal tar as the film-forming material. They are made by adding various rust-proof pigments, insulating fillers, toughening agents, leveling agents, diluents, anti-settling agents, etc. Group B is a modified amine curing agent or a curing agent-based material, mixed with pigments and fillers. This product is supplied with A and B components matched at the time of sale. They are mixed in the specified ratio during application, ensuring thorough mixing and use within the designated time frame.
