The paint film of the external anti-corrosion layer of epoxy coal tar anti-corrosion steel pipe never falls off or cracks, and the construction performance is very good. Both dramatic coating and spray coating are available, with a paint film of up to 100 microns by brushing, saving labor and materials, and having a low cost. Epoxy asphalt anti-corrosion coating absorbs the excellent adhesion, mechanical strength, and solvent resistance of asphalt coating in terms of water resistance, acid and alkali resistance, and flexibility, and appropriately improves the weather resistance of epoxy resin coating.

Epoxy coal tar anti-corrosion coating is composed of two main components: epoxy and coal tar. It is a two-component coating of A (epoxy) and B (curing agent), which has excellent adhesion, toughness, moisture resistance, water resistance, and chemical resistance. It has the performance of preventing various ions from passing through the paint film and has the characteristics of expansion and contraction with the coated object. The paint film never falls off or cracks. Thickness of 0.5-1.0mm.

Epoxy coal tar is a cost-effective form of anti-corrosion, and engineering tests have shown that using epoxy coal tar combined with cathodic protection. Oil and gas pipelines have been used for 20 years without any corrosion.

Application scope of epoxy coal tar anti-corrosion steel pipe:

Epoxy coal tar anti-corrosion steel pipes are mainly used for anti-corrosion of the outer walls of buried or underwater steel oil, gas, water, and heating pipelines. They are also suitable for anti-corrosion of various steel structures, docks, ships, water gates, gas storage tanks, refinery and chemical plant equipment, as well as waterproofing and leakage prevention of concrete structures such as concrete pipes, sewage tanks, rooftop waterproof layers, bathrooms, basements, etc.

Characteristics of epoxy coal tar anti-corrosion steel pipe:

1. Epoxy coal tar anti-corrosion steel pipe is a high-performance anti-corrosion coating with a smooth, dense, and hard coating, strong adhesion, and good resistance to salt alkali, seawater, soil microbial corrosion, and plant root penetration. The composite use of paint and fiberglass cloth can enhance the mechanical properties of the anti-corrosion layer.

2. Room temperature coating, natural curing, easy to apply, can be manually or mechanically applied, especially suitable for on-site use.
