Water supply epoxy coal tar anti-corrosion steel pipe manufacturer for internal and external anti-corrosion steel pipes

Description :

　　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. The components are epoxy coal tar primer and topcoat, both of which are mainly composed of epoxy resin and coal tar as film-forming materials, and are made by adding various anti rust pigments, insulating fillers, toughening agents, leveling agents, diluents, anti settling agents, etc. The B component is a modified amine curing agent or a curing agent as the main material, and is made by adding pigments and fillers. When this product is sold, components A and B are supplied together and mixed in proportion during construction.

　　The three cloth and five oil anti-corrosion steel pipes carefully crafted by epoxy coal tar anti-corrosion steel pipe manufacturers for oil pipelines have been widely used in Hubei Sinopec oil pipelines, and the product quality has withstood the strict test of practice. Only products that have been proven reliable through practical testing are truly good products, more convincing than any advertisement. Sincerely welcome customers and friends to call and negotiate! It is mainly used for anti-corrosion of the outer walls of buried or underwater steel oil, gas, water, and heating pipelines. It is also suitable for anti-corrosion of various steel structures, docks, ships, water gates, gas storage tanks, equipment in refineries and chemical plants, as well as waterproofing and leakage prevention of concrete pipes, sewage tanks, roof waterproof layers, bathrooms, basements, and other concrete structures. It can be said that the application of epoxy coal tar pitch is very extensive, and its performance after drying is also excellent. However, during storage and use, it is easy to deteriorate due to high temperature or humidity. Therefore, before drying and forming, it should be kept away from heat sources or open flames, and should not be exposed to humid environments.

　　Spiral steel pipes are coated with oil and wrapped with cloth for anti-corrosion. Our company supplies three oil and two cloth anti-corrosion steel pipes all year round. Our company has an advanced anti-corrosion production line of three-layer polypropylene (3PP). Through a series of new technologies such as overall heating and deformation, it has made a qualitative leap and can be widely used in the medium and high pressure fields, while straight seam welded pipes can only be limited to water and gas transportation in low-pressure environments. Although some people currently have a vague understanding of seamless steel pipes, heat tension reducing steel pipes, and straight steel insulated pipe seam welded pipes, we believe that with the passage of time and practical experience, people will have a correct understanding of this unique product, heat tension reducing steel pipes, and make them play an increasingly important role in the seamless steel pipe market, creating greater economic benefits for society! After high-frequency welding, carbon cannot accumulate in the straight seam of welded pipes. The latter, based on the straight seam welded pipe, has undergone online internal and external burr welds that are only connected to the parent body, without fully melting into one, and cannot withstand the test of time and high pressure. Common ones include one cloth with two oils, three cloths with two oils, five steps with three oils, and seven cloths with four oils. The components of epoxy coal tar anti-corrosion spiral steel pipe are epoxy coal tar primer and topcoat.

　　Its application is very common in underground oil pipelines, such as epoxy coal tar anti-corrosion steel pipes, which are pipeline facilities mainly composed of steel pipes and epoxy coal tar coatings. The performance is quite good, and it can effectively transport relevant media in underground environments with high efficiency and good resistance to various corrosion. It is a commonly used underground oil pipeline. Appearance of epoxy coal tar anti-corrosion steel pipe: Primer component A is iron red, component B is black, and the topcoat is black. It has excellent resistance to chemical media corrosion and good physical and mechanical properties, good adhesion, tough coating, as well as excellent electrical insulation and anti permeability, anti stray current and anti microbial erosion. After film formation, it can reduce the number of construction passes. The main implementation standards are "Technical Standard for Epoxy Coal Tar Anti corrosion Coating of Buried Steel Pipeline" and "Technical Standard for Liquid Epoxy Coating Internal Anti corrosion Coating of Steel Pipeline". It is mainly used for anti-corrosion of the outer walls of buried or underwater steel oil, gas, water, and heating pipelines. It is also suitable for anti-corrosion of various steel structures, docks, ships, water gates, gas storage tanks, equipment in refineries and chemical plants, as well as waterproofing and leakage prevention of concrete pipes, sewage tanks, roof waterproof layers, bathrooms, basements, and other concrete structures.
