Due to pipe anticorrosion technology lag behind even some carbon steel pipe before no treatment done by corrosion of experience wind and rain, there are a lot of water, gas, natural gas and other metal pipe rust, near the interface is particularly serious, many years of metal pipe is used, is now "with" rotting, interface and the distance between the place of anti-corrosion steel pipe little rust.
Metal pipe joints, about 30 centimeters rust obviously serious, its service life more than any other place in the same period installation of the pipe at least by half, which in turn increases the change of frequency, not only the economic burden, increase users construction also affect people's normal life. Near the interface rust heavily in other places, the main reason is that when cutting thread, processing and installation, destroyed the rust layer on the surface of the galvanized tube, it not only shorten the service life of the metal tube, also laid the security hidden danger. Such as coal gas and natural gas pipelines, serious rust near the interface, easy to cause gas leakage cause safety accidents. Pipe due to rust and blowout, will affect public life. At the top of metal rust, may also hurt people.
China's current of zinc reserves of natural resources in accordance with the existing production capacity, guarantee the mining life is shorter. In today's increasingly scarce resources, zinc is so scarce, we should cherish it with it. Advocate low carbon life, is to make full use of resources. Mild steel pipe caused by man-made destruction, its service life, it's not "low carbon". Zinc has excellent atmospheric corrosion resistance, so the zinc is mainly used for steel and steel structure of the surface coating. According to data shows, since 2003, China's zinc production for 12 years, consumption for six years the highest in the world.
Extend the service life of metal tube near interface of is. Installation of pipes, for surface rust layer of the damaged place, in a timely manner after the completion of coated with antirust paint or glass glue, regular maintenance in the future. This work, it is best done by the contractor, because involves aerial work, user is difficult to operate. Above is a small project, general big engineering will use finished anti-corrosion steel pipe buried pipeline, the pipeline anticorrosion technology is more advanced, anti-corrosion steel pipe use fixed number of year up to 50 years.
Hunan Great Steel Pipe Co.,ltd is good supplier of coating steel pipe.
