Shandong Xinyuantai Pipe & Pipe Co., Ltd. provides a new method for anticorrosion of ductile iron pipes in 2012. Corrosion protection is an issue worth paying attention to in the steel industry. We must pay more attention to the corrosion protection of ductile iron pipes.
Ductile iron pipe is a long-term and safe use of the directly related anticorrosion pipe, and therefore is an important indicator to measure the network technology and operating conditions. Graphite in cast iron and graphite spheroidal graphite cast iron do not affect the city where the mechanical and mechanical properties of the matrix are very typical. However, according to surveys, the leakage rate of urban water supply pipe network in China is 12-13%, far exceeding the national interest rate of 6%. The city's leaks are controlled under the following criteria, therefore, pipeline corrosion has always been a hot topic in our current. The research of this topic will be answered by a dedicated technical staff. If you have any questions, please visit our company. I believe that you will have different results, and these results of your ductile iron pipe are absolutely necessary to understand. In 1984, the Water Research Center concluded that the anticorrosive zinc layer of the ductile iron pipe is very important and can effectively reduce corrosion. Saint-Gobain-Mass-Joejo believes that in order to strengthen the anti-corrosion capability of the pipeline, it is necessary to increase the zinc layer density to 200 g/m2. Ductile iron pipe, so far, zinc plus asphalt antisepsis is the best and most basic protective material. Pipes laid in areas with high corrosivity can be formed on the basis of basic protective layers, and polyethylene films, polyurethane coatings, or polyethylene coatings, for special protection. The improvement of anti-corrosion technology also proves that the ductile iron pipe industry also has some changes, or it can be said to be a technological update.
External anti-corrosion can also first remove the impurities on the surface of the pipe or pipe fittings, and then perform zinc spray treatment (130g/m3). Finally, the effect of the asphalt paint coating is not less than 70μm.
