With the continuous development of the international construction industry, the pipeline construction skills and construction quality also put forward higher and higher requirements on the buried steel pipe
outside the corrosion, and now we have screened a petroleum asphalt anti-corrosion, the same choice of epoxy coal Asphalt anti-corrosion steel pipe. Advantages of coal tar pitch anticorrosive steel pipe is: 1. Both coal tar pitch water resistance, excellent anti-rust function, the advantages of bacterial resistance to corrosion, but also a tough epoxy coating, good adhesion, high mechanical strength Features.
Epoxy coal tar pitch pipe corrosion (three cloth two oil pipe corrosion): Epoxy resin + coal tar pitch + filler made of paint in the steel exterior with glass cloth as a coating made of reinforced coating, the thickness of 0.5 ~ 1.0mm . According to customer-made three cloth two oil four cloth two oil. Epoxy coal tar pitch pipe corrosion (three cloth two oil pipe corrosion) Features: Tough tough fullness, strong adhesion Has excellent chemical resistance Corrosion resistance, excellent water resistance, anti-microbial corrosion Epoxy coal tar primer and epoxy Two types of coal tar finish. The company's epoxy coal tar pitch primer for the solvent-based products; epoxy coal tar topcoats for the series of products, according to the solid content is divided into solvent-free type (GH201) and thick type (GH202) two types, according to the coating The heat-resistant temperature is divided into temperature-resistant type (at 150 ℃, filling W) and standard (used at 100 ℃), for users according to the anti-corrosion engineering practice requirements.

The company is located in:
Epoxy coal tar pitch anticorrosion steel pipe is divided into epoxy coal tar primer and topcoat, are based on epoxy resin and coal tar pitch as the main film, add a variety of anti-rust paint, insulating filler, toughening agent, leveling Agent, thinner, anti-settling agent and other components, B component is a modified amine curing agent or curing agent-based material, adding pigments and fillers made. When the product is sold, the A and B components will be supplied. When the products are mixed, they should be mixed according to the quotas when they are used. When the products are evenly mixed, they should be used up within the stipulated time. Spiral coal tar pitch corrosion spiral steel pipe is what we often say a few cloth oil, a common two cloth oil, three oil two cloth, three cloth four oil, three cloth five oil, six oil two cloth, four cloth six oil. Epoxy coal tar pitch corrosion spiral steel pipe components for the epoxy coal tar primer and paint, are based on epoxy resin and coal tar pitch as the main film, add a variety of anti-rust paint, insulating filler, toughening agent, Leveling agent, thinner, anti-settling agent and the like. Appearance: A red iron primer component, B black component, the paint is black.
Epoxy coal tar pitch anticorrosive steel pipe is now evaluated at home and abroad role of the coating is very good. The shortcomings reported in the application of its few. The first reported drawbacks are dew point. Peeling. Cathode stripping. Cathodic protection shield. Peel the coating film Corrosion and so on.And most of the shortcomings of the report is still stuck in the theoretical stage of estimation.As mentioned in the material referred to the cathodic protection shield.Up to now there is no practical examples of the protection of the cathodic protection shield reported in practice.After many years The practice marked. Follow the use of the added years. The scope of application Mainly used in buried or underwater steel oil. Gas. Water supply. Heating pipe wall corrosion. Also applies to all types of steel structure. Wharf. Ships. Sluice Gas storage tanks. Petrochemical plant anti-corrosion and concrete pipe. Sinks. Roof waterproof. Toilet. Basement and other concrete structures waterproof and anti-seepage. , A common two cloth oil, three cloth two oil, five three oil, seven cloth four oil.
