Code for Installation and Construction of Ductile Iron Pipes

Prestressed concrete pipes have been put into production in China since 1968, and the pipe making technology of ductile iron pipes has also been gradually improved with the development of industrial technology. Due to the limitation of the tightness of the interface, they are generally used for working pressure below 0.6Mpa, and their diameters are ideal within the range of 1000-1400mm. Ductile iron pipe, mainly used in water supply and gas pipeline engineering, is a kind of pipe with great development prospects.

Short Process Casting Technology of "Blast Furnace+Electric Furnace"

Grey cast iron pipes are brittle materials, and about 5% of them are damaged during transportation. In addition, they have poor adaptability to earthquake and other dynamic loads, as well as various stresses occurring during operation. Accidents occur at leisure, especially for large diameter gray cast iron pipes. There are few reports on the use of prestressed concrete pipes to transport gas and water abroad. The use pressure of gray cast iron pipe for water delivery is 0.6Mpa, and when the diameter is greater than 600mm, the pipe explosion accident occurs in the process of operation. The reliability lies in the guaranteed service life of the pipe body, sealing ring and accessories against the corrosion of the intermediary soil. It also produces horizontal and vertical nodular cast iron condensate cylinders for gas, with complete product specifications and accessories.

Casting Technology of Ductile Iron Pipe

The sliding type and mechanical flexible interface mode are adopted, and the construction is simple. And it can operate safely for a long time. The compressive strength of ductile iron pipe is higher than that of steel pipe.
