Cast iron pipes are used for water supply, drainage and gas pipelines, and include straight cast iron pipes and pipe fittings. Labor intensity is small. According to different casting methods, it is divided into continuous cast iron pipe and centrifugal cast iron pipe. Among them, centrifugal cast iron pipe is divided into sand mold and metal mold. According to different materials, it is divided into gray cast iron pipe and ductile iron pipe. According to different interface forms, it can be divided into flexible interface, flange interface, self-anchored interface, rigid interface, etc. Among them, the flexible cast iron pipe is sealed with a rubber ring; the flange interface cast iron pipe is fixed with a flange, and the inner gasket is sealed with a rubber flange gasket; the rigid interface generally has a larger socket for the cast iron pipe. After the straight pipe is inserted, it is sealed with cement

Ductile iron pipe is a kind of cast iron pipe. In terms of quality, the spheroidization grade of the cast iron pipe is required to be controlled at 1-3 (spheroidization rate 80%), so the mechanical properties of the material itself have been better improved, with the essence of iron and the performance of steel. The annealed ductile iron pipe has a metallographic structure of ferrite plus a small amount of pearlite, good mechanical properties, excellent corrosion resistance, good ductility, good sealing effect, easy installation, and mainly used for water supply and gas transmission in municipalities, industrial and mining enterprises , Oil and so on.
A certain amount of spheroidal graphite is distributed on the ferrite and pearlite matrix. According to the nominal diameter and the requirements for elongation, the ratio of ferrite and pearlite in the matrix structure is different. The ratio of pearlite with small diameter Generally, it is not more than 20%, and the large-caliber is generally controlled at about 25%.
It is suitable for the domestic drainage pipes of socket type and clamp type connection of gray cast iron pipes and supporting pipe fittings with internal and external pipe diameters of DN50mm~DN300mm and internal pressure not greater than 0.3MPa in new construction, expansion and reconstruction of civil and industrial buildings. , Rainwater pipes, non-corrosive industrial production wastewater pipes and rain down pipes.
