Epoxy coal tar asphalt anticorrosive steel pipes are coated with a protective layer made from a paint consisting of epoxy resin, coal tar asphalt, and fillers, applied to the steel pipe surface using glass cloth. This product is also known as 2-burlap 1-oil, 3-burlap 2-oil, or 4-burlap 3-oil, and is primarily used for the external anticorrosion of buried or underwater steel pipelines for oil, gas, water supply, and heating. It is also suitable for the anticorrosion of various steel structures, docks, ships, sluices, gas storage tanks, equipment in oil refineries and chemical plants, as well as for waterproofing and leakage prevention in concrete structures such as concrete pipes, sewage pools, roof waterproofing layers, bathrooms, basements, and more.

Product Categories
1. By Shape Classification
Steel pipes can be categorized by shape into: round pipes, square pipes, rectangular pipes, octagonal pipes, hexagonal pipes, D-shaped pipes, pentagonal pipes, and other special-shaped steel pipes, complex cross-section pipes, double concave pipes, five-petaled plum blossom-shaped pipes, conical pipes, corrugated pipes, melon-shaped pipes, double convex pipes, and more.
2. Categorized by Usage
Steel pipes are categorized by their applications, including pipeline steel pipes, thermal equipment steel pipes, mechanical industry steel pipes, oil and geological drilling steel pipes, container steel pipes, chemical industry steel pipes, and special-purpose steel pipes.

Product Features
1. This product is an anti-corrosion paint, featuring a smooth, dense, and hard coating with strong adhesion. It excels in resistance to salt and alkali, seawater, soil microbial corrosion, and plant root penetration. When combined with glass fiber cloth, it enhances the mechanical properties of the anti-corrosion layer.
2. Room temperature application, self-curing, easy to install, suitable for both manual and mechanical application, ideal for on-site use.

Technical Specifications
Epoxy coal tar coatings are divided into two categories based on their application functions: epoxy coal tar primers and topcoats. Our company's epoxy coal tar primers are solvent-based products; the topcoats are a series of products, categorized into solventless (GH201) and thick-body (GH202) based on solid content, and further divided into heat-resistant (useable up to 150°C, marked with W) and standard types (useable up to 100°C) based on the heat resistance of the coating during application. These are offered to customers for selection according to their actual anti-corrosion engineering requirements.
