Epoxy coal tar pitch corrosion seamless steel pipe

With the continuous development of the international construction industry, the construction technology and quality of the pipeline also put forward higher and higher requirements for the external corrosion of the buried steel pipe. Now we have screened out the petroleum asphalt anti-corrosion, and the same coal asphalt anti-corrosion steel pipe is selected for epoxy. The advantages of coal tar pitch anticorrosive steel pipe are as follows: 1. It has the waterproof performance of coal tar pitch, excellent antirust function, and the advantages of bacterial corrosion resistance. It also has the characteristics of tough epoxy coating, good adhesion and high mechanical strength.



Epoxy coal tar pitch pipe corrosion (three cloth and two oil pipes corrosion): the paint made of epoxy resin + coal tar pitch + filler, and the coating made of glass cloth as reinforcement coating on the outer surface of steel, with a thickness of 0.5-1.0mm. Make three cloth and two oil according to customer's requirement. The characteristics of epoxy coal tar pitch pipe corrosion (three cloth two oil pipe corrosion): strong toughness, strong fullness, strong adhesion, excellent chemical corrosion resistance, excellent water resistance, antibacterial epoxy coal tar oil primer and epoxy two types of coal tar finish. The company's epoxy coal tar pitch primer is used for solvent based products; the epoxy coal tar finish is a series of products, which can be divided into solvent-free type (gh201) and concentrated type (GH202) according to the solid content. According to the heat-resistant temperature of the coating, it can be divided into temperature resistant type (at 150 ℃, filled with W) and standard (used at 100 ℃), for the user to carry out according to the requirements of corrosion engineering practice.

Epoxy coal tar pitch anticorrosive steel pipe is divided into epoxy coal tar oil primer and finish coat, all of which are made of epoxy resin and coal tar pitch as the main film, with various components such as antirust paint, insulation filler, toughener, leveling agent, diluent, anti settling agent, etc. component B is the material mainly composed of modified amine curing agent or curing agent, with pigment and filler added. A and B components will be provided when the product is sold. When mixing products, they should be mixed according to the use quota. After the product is mixed evenly, it shall be used up within the specified time. Spiral coal tar pitch corrosion spiral steel pipe is often said to be several kinds of oil distribution, a common two cloth oil, three kinds of oil two cloth, three cloth four oil, three cloth five oil, six oil two cloth, four cloth six oil. Epoxy coal tar pitch anti-corrosion spiral steel pipe component is used as the primer and coating of epoxy coal tar pitch. Epoxy resin and coal tar pitch are used as the main film-forming agent, and a variety of antirust coating, insulation filler, toughening agent, leveling agent, diluent, anti settling agent, etc. are added. Appearance: red iron primer, b black, black paint.



At present, the coating of epoxy coal tar pitch anticorrosive steel pipe is very good at home and abroad. The disadvantage is that there are few reports in application. The first drawback is the dew point. Peeling cathode stripping. Cathodic protection cover. Most of the defects in the report are still in the theoretical estimation stage, as mentioned in the materials of cathodic protection cover, so far there is no actual protection case reported in practice. Years of practice mark. Use according to the year of increase. The scope of application is mainly used in underground or underwater steel oil. Gas station. Water supply. Corrosion of heating pipe wall. It also applies to all types of steel structures. Wharf. Ships. Gate air storage tank. Anticorrosive concrete pipe of petrochemical plant. Water tank. Roof waterproofing. Toilet. Basement and other concrete structures are waterproof and impervious. The common ones are two cloth oil, three cloth two oil, five cloth three oil, seven cloth four oil.
