　　Safety is the necessity of the times, innovation is the foundation of survival, and quality is the guarantee of enterprises; During the production pouring of the bridge drainage pipe in our factory, induction furnace melting is often used to effectively control the temperature of the molten iron; Because excessive pouring temperature can cause the sand mold to expand, and when the pouring temperature is ≥ 1420 ℃, the amount of waste will increase; When the pouring temperature is 1460 ℃, the waste reaches 50%. Therefore, customers can rest assured to purchase our cast iron drain pipe, which meets the wall thickness standard, has excellent quality, and can be delivered quickly.

　　Against the backdrop of the current severe situation in China's steel industry, anti-dumping investigations into China's steel industry by countries around the world are increasing day by day. Yesterday, the website of the Ministry of Commerce announced that the Foreign Trade Department of the Colombian Ministry of Trade and Industry has decided to launch an anti-dumping investigation on steel wire originating in China.

　　The anti-corrosion process of cast iron drainage pipes for bridges determines whether they will rust or not. Whether it will rust or not depends on whether the anti-corrosion process of the pipe is done properly. Qualified cast iron pipes require lining with standard thick cement; The outer wall of the pipe requires zinc spraying treatment and asphalt paint coating, and other epoxy resin paints can also be selected. Qualified cast iron drainage pipes can be used for more than a hundred years, and the main area prone to rusting is the contact between the outer wall and soil, due to its high humidity and oxygen content. And qualified anti-corrosion can effectively resist rust. Although there is water flow for a long time, oxygen is scarce and less prone to corrosion compared to the outer wall, but a cement lining is necessary.
