What is epoxy coal anti-corrosion steel pipe? 

The epoxy coal asphalt anticorrosive coating consists of epoxy and coal tar pitch, is a (epoxy) B (curing agent) Two-part coating, with excellent adhesion, tenacity, moisture resistance, water resistance, chemical medium, with a variety of ions to prevent the performance of the film through the paint, with the coated objects with the expansion of the same shrinkage characteristics. Paint film never fall off, cracking. Thickness 0.5~1.0mm. Epoxy Coal tar pitch is a kind of anti-corrosion form with high cost-performance, and the engineering test shows that the epoxy coal tar pitch is applied to cathodic protection.
 

    Oil and gas pipelines used for 20 years basically did not occur corrosion phenomenon. Epoxy coal asphalt anti-corrosion steel pipe used in the paint, is made of epoxy resin, coal tar pitch, antirust pigments, additives, modified amine prepared. Products with fast drying, good adhesion, flexibility, two-component packaging, construction convenience. With acid, alkali resistance, salt, water resistance, oil and other characteristics.
 

    The paint synthesizes the characteristics of high mechanical strength of epoxy resin, strong adhesion, resistance to chemical media, water resistance, microorganism resistance and plant root, and is a high-performance anti-corrosion insulating coating, which has good chemical resistance and water resistance.

 

It is suitable for oil and gas transmission, pipeline, water, gas, pipe, oil refinery, chemical plant, sewage treatment plant equipment and pipelines anti-corrosion, can also be used as offshore oil drilling platform and ship under the water anti-corrosion and mine, underground facilities anti-corrosion. We all know epoxy coal asphalt anti-corrosion steel pipe, rot steel pipe before doing anti-corrosion should be done first rust, the following has Cangzhou anti-corrosion Steel pipe Factory Valley Manager for you to introduce the way to remove rust: spray (throw) The removal of rust is through high-power motor-driven spray (cast) blade high-speed rotation, so that steel sand, steel pill, wire section,
 

     Mineral materials such as centrifugal force on the surface of steel pipe spray (cast), not only can thoroughly remove rust, oxides and dirt, and steel pipe in the abrasive impact and friction force, but also to achieve the required uniform roughness. After spraying and removing rust, the epoxy coal tar-coated steel pipe can not only enlarge the physical adsorption on the surface of the tube, but also enhance the mechanical adhesion between the anti-corrosion layer and the surface of the pipe. Therefore, spraying (throwing) the removal of rust is the ideal way to rust pipeline anti-corrosion. In general, shot peening (sand) derusting is mainly used in the internal surface treatment of pipes, blasting (sand) derusting mainly used for outside the pipe surface treatment.
 

    The removal process can be achieved near-white (Sa2.5) technical conditions with lower operating costs and stable and reliable quality.
 

    Epoxy coal asphalt anti-corrosion steel pipe operation process Simple, reasonable price, convenient welding, it is the drainage pipeline anti-corrosion steel pipe in the king, commonly known as drainage overlord Pipe, the service life of 40-45 years early. There are many varieties of epoxy coal asphalt anti-corrosion steel pipe, especially the thickness difference, there are two cloth three oil epoxy coal asphalt anti-corrosion steel pipe, there are two cloth six oil practice (epoxy coal asphalt anti-corrosion steel pipe), there are four cloth six oil epoxy coal asphalt anti-corrosion steel pipe, is always what kind of engineering with what kind of epoxy coal asphalt anti-corrosion steel pipe, The best epoxy coal asphalt anti-corrosion steel pipe thickness reached 500 microns, ignition flower can be measured to 5000 volts, commonly used in drainage pipelines, sewage pipes anti-corrosion pipe, chemical drainage pipelines. Corrosion-resistant steel pipe types are: Epoxy coal asphalt anti-corrosion steel pipe, 3pe anti-corrosion steel pipe, cement mortar anti-corrosion steel pipe, epoxy powder anti-corrosion steel pipe, 8710 non-toxic water pipe anti-corrosion pipe and so on.
