Epoxy tube counterattacks the market, companies express optimism
With the continuous development of municipal construction, higher and higher requirements have also been put forward for the construction technology and construction quality of pipelines. For the external anti-corrosion of buried steel pipes, we have eliminated the external anti-corrosion of petroleum asphalt and uniformly used epoxy coal. Asphalt anti-corrosion steel pipe. The advantages of using epoxy coal tar pitch anti-corrosion steel pipes are: 1. It has the advantages of good coal tar pitch, good water resistance, excellent rust resistance, and bacterial erosion resistance, as well as tough epoxy resin paint film, good adhesion and high mechanical strength. Features. 2. The film-forming coating has relatively stable chemical resistance, electrical insulation, microbial erosion resistance, and seawater resistance. In particular, the water absorption rate is small, and it is far more resistant to microbial erosion than petroleum asphalt. 3. Long service life. In order to correctly use epoxy coal tar pitch anti-corrosion steel pipes for buried steel pipes, ensure the quality of the anti-corrosion layer and prolong the service life of buried steel pipes, construction should be carried out in strict accordance with the following requirements: 1. Construction technical requirements 1. Steel pipe surface treatment. Generally, the surface of the steel pipe has oxide scale, rust, oil pollution, dust, etc. If it is not treated, it will directly affect the adhesion of the coating. The surface can reach SaZ (l/2) level (with the naked eye, there are obvious hair lines on the surface), and the primer should be applied within 6h after removing the rust. 2. Apply primer. The primer can be applied with a roller brush or a paint brush. The primer should be applied as thinly as possible, generally 30 m to 5 m, and it should be noted that the paint film is uniform and does not leak.
