What are the specifications of cast iron pipes?
Compared with grey cast iron pipe, ductile iron pipe has higher strength, better toughness, thinner tube wall, less metal consumption, and can bear higher pressure. The effective length is 5 meters and 6 meters. According to the wall thickness, it is divided into two grades P and G. It is the development direction of cast iron pipe.
The nominal diameter of the continuous grey cast iron pipe is 75~1200 mm. It adopts the form of socket type or flange disk interface. It can be divided into two kinds of flexible interface and rigid interface according to function. The length of the straight pipe is 4 meters, 5 meters and 6 meters. According to the wall thickness, LA, A and B are divided into three grades. The nominal diameter of the centrifugal cast iron pipe of the sand mould is 200~1000 mm, the effective length is 5 meters and 6 meters. According to the wall thickness, it is divided into two grades: P and G. High strength, good toughness, thin tube wall, little metal consumption, and can bear higher pressure,
To be divided into: cast cast pipe. Cast iron pipes are used for water supply, drainage and gas transmission lines. They include cast iron pipes and pipe fittings. Labor intensity is small. According to the casting method, it is divided into continuous cast iron pipe and centrifugal cast iron pipe, in which the centrifugal cast iron pipe is divided into sand mould and metal type two kinds. Divided into gray cast iron pipe and nodular cast iron pipe according to different material. Rubber ring seals for flexible interfaces,
