Why do ductile iron pipe fittings have sand holes?

2024-07-01

Ductile iron pipes are made of magnesium or rare earth magnesium combined with gold spheroidizers added to molten iron before pouring to spheroidize graphite and reduce stress concentration, so that the pipe has the advantages of high strength, high elongation, impact resistance, corrosion resistance, and good sealing.

Disadvantages: In high-pressure pipe networks, it is generally not used and has low pressure resistance. Because the pipe body is relatively bulky, machinery must be used during installation. my country produces 1.5 million tons of ductile iron pipes and 50,000 tons of matching pipe fittings annually. The products have been successfully used in the construction of national and local key projects such as the Taiyuan Yellow River Diversion Project, the Lanzhou Yellow River Diversion Project, the Nanjing Jiangning Water Supply Project, the Xi'an Urban Water Environment Management Phase II Project, and the Baoji Urban Emergency Water Supply Project. With excellent quality and good service, it has won the general recognition of users and is currently recognized as a leading enterprise in the industry.

One of the key advantages of ductile iron pipe is its strength and durability.

In addition to its strength, ductile iron pipe is also highly resistant to corrosion. The pipe's internal and external surfaces are coated with a protective layer of cement mortar or a layer of zinc coating, which helps prevent corrosion and extend the pipe's service life. This corrosion resistance is particularly important for water distribution systems, where the pipe is constantly exposed to moisture and chemicals.
