During the construction of ductile iron pipes, the quality of the lower pipes determines the reliability and quality of operation and other factors. According to the characteristics and characteristics of ductile iron pipes, it is recommended to adopt the following forms of lowering operations

The production process of ductile iron pipes is to add magnesium, calcium and other alkaline earth metals or rare metals to the raw materials of ordinary cast iron pipes.

There are mainly the following specifications: the smallest specification in China is DN80, and the cost of a smaller specification than DN80 is too high, and generally welded pipes are used instead

The installation procedure for ductile iron pipe connection is:
Clean the socket of the socket→clean the apron→upper the apron→lower the pipe (pipe)→ brush lubricant on the surface of the socket and the apron→push the pipe to insert it into the socket→check

In industrial production, ductile cast pipe is a commonly used pipe material, and due to the technological characteristics of ductile iron pipe, it has obvious advantages in the market

In our daily life, we can often see that many families will invite technicians to clear the pipes. They spend a lot of money and time. Compared with ductile iron pipes before they are put on the market, manufacturers will put The inner wall of the pipe is coated with epoxy coal tar pitc
