2-layer, 4-oil coated anti-corrosion steel pipe

2-Layer 4-Oil Anti-corrosion Steel Pipe/2L4O Anti-corrosion Steel Pipe, Our company supplies 3-Layer 2-Layer Anti-corrosion Steel Pipe, Reinforced 3-Layer 2-Layer Anti-corrosion Steel Pipe, Asphalt Oil Anti-corrosion Steel Pipe, Epoxy Coal Tar 3-Layer 2-Layer Anti-corrosion, Anti-corrosion Steel Pipe for Sewage Pipeline, Buried Steel Pipe Anti-corrosion, and other products. We always adhere to the corporate philosophy of "Quality First, Integrity as the Foundation" and the business tenet of "Customer-Centric, Integrity as the Core," striving to build a standard system based on management, centered on customers, led by technology, and lifeblood by quality. Epoxy Coal Tar Anti-corrosion Spiral Steel Pipe, commonly known as "X-Layer Y-Oil," includes types such as 1-Layer 2-Oil, 3-Layer 2-Oil, 5-Layer 3-Oil, and 7-Layer 4-Oil. The components of Epoxy Coal Tar Anti-corrosion Spiral Steel Pipe are the epoxy coal tar primer and topcoat, both of which are made primarily from epoxy resin and coal tar, with various anti-rust pigments, insulating fillers, toughening agents, leveling agents, diluents, and anti-settling agents added. Appearance: the primer's A component is iron red, the B component is black, and the topcoat is all black. It boasts excellent resistance to chemical medium corrosion and good physical and mechanical properties. It has good adhesion, a tough film, and excellent electrical insulation and anti-permeability, resistance to stray currents and microbial侵蚀, and can reduce the number of application layers after curing. The main execution standards are SY/T0447-96 "Technical Standard for Epoxy Coal Tar Coating on Buried Steel Pipes" and SY/T0457-2000 "Technical Standard for Internal Liquid Epoxy Coating on Steel Pipes." It is mainly used for the external anti-corrosion of buried or underwater steel pipelines for oil, gas, water supply, and heating, and is also suitable for the anti-corrosion of various steel structures, docks, ships, sluices, gas storage tanks, oil refining and chemical plant equipment, and concrete pipes, sewage pools, roof waterproofing layers, bathrooms, basements, and other concrete structures for waterproofing and anti-seepage. Epoxy Coal Tar anti-corrosion paint is composed of two main components: epoxy and coal tar, and is a two-component paint (A component: epoxy, B component: hardener), with excellent adhesion, toughness, resistance to moisture, water, and chemical mediums, and the ability to prevent various ions from passing through the paint film.

2-Ply 4-Oil Anti-corrosion Steel Pipe, featuring the same expansion and contraction characteristics as the coated item. The coating never peels off or cracks. Thickness: 0.5～1.0mm. Epoxy coal tar is a cost-effective anti-corrosion method. Field tests show that with the addition of cathodic protection, oil and gas pipelines using epoxy coal tar can last for twenty years without significant corrosion. The components include epoxy coal tar primer and topcoat, both mainly composed of epoxy resin and coal tar, with various rust-proof pigments, insulating fillers, toughening agents, leveling agents, thinners, and anti-settling agents added. The B component is a modified amine curing agent or a curing agent-based material, mixed with pigments and fillers. When sold, the product comes with A and B components matched for supply. They are mixed in the specified ratio, stirred thoroughly, and used within the designated time frame. Specializing in the production of 3-oil 2-fabric anti-corrosion steel pipes, our company supplies: 3-oil 2-fabric anti-corrosion spiral steel pipe, 3-oil 2-fabric anti-corrosion straight seam steel pipe, 3-oil 2-fabric anti-corrosion seamless steel pipe, and 3-oil 2-fabric epoxy coal tar anti-corrosion steel pipe.
