Various pipe diameter specifications: ductile iron pipe has a variety of pipe diameters to choose from, as small as DN80mm, as large as DN2600mm or even larger. In the urban water supply network, the large-diameter ductile iron pipe can be used for the main pipe to transport water, which can meet the demand of large-scale water supply. In the water supply network within the community or factory, smaller pipe sizes can be used for branch pipes to accurately deliver water to each user terminal.

for ductile iron and other iron pipes, has a high ability to withstand water pressure, but also to withstand the external load, but also to adapt to various geological conditions. The strength of the pipe is very high, and it also has certain advantages in hardness, corrosion resistance, flexibility and so on.

Nodular cast iron and gray cast iron have great differences in solidification characteristics, mainly in the following aspects:

clean the rubber ring cover and the rubber ring cover, wipe off any adhesive dirt, put the rubber ring cover in the socket in the figure 8 groove, and along the rubber ring cover compacts around it.
