Cast Iron Pipe

Cast iron pipe, a tube cast from cast iron. Cast iron pipes are used for water, drainage and gas transfer lines, which include cast iron straight pipes and fittings. Labor intensity is small. According to different casting methods, it is divided into continuous cast iron pipe and centrifugal cast iron pipe. The centrifugal cast iron pipe is divided into sand type and metal type. According to the material, it is divided into gray cast iron pipe and ductile iron pipe. According to the interface form, it is divided into flexible interface, flange interface, self-anchored interface, rigid interface and so on. Among them, the flexible cast iron pipe is sealed with rubber ring; the flange interface cast iron pipe is fixed by flange, the inner pad rubber flange gasket is sealed; the rigid joint generally has a large cast iron pipe socket, and the straight pipe is inserted and sealed with cement. This process is now Basic elimination.

According to its manufacturing method, it can be divided into: sand type centrifugal socket straight pipe, continuous cast iron straight pipe and sand type iron pipe.

According to the materials used, it can be divided into: gray iron pipe, ductile iron pipe and high silicon iron pipe.
1. Water supply cast iron pipe:
The cast iron pipe of the water supply cast iron pipe is made by casting the molten iron of No. 18 or higher and adding the spheroidizing agent to the pipe by high-speed centrifugal casting of the centrifugal ductile iron machine. The ductile iron pipe has the iron essence, the steel property, the anticorrosion performance is excellent, the ductility is good, and the seal is good. The effect is good, the installation is simple, and it is mainly used for water supply, gas transmission and oil transportation of municipal, industrial and mining enterprises. It is the first choice for water supply pipes and has a high cost performance.

2. Sand type centrifugal cast iron straight pipe:
The material of the sand type centrifugal cast iron straight pipe is gray cast iron, which is suitable for the transportation of pressure fluid such as water and gas.

3. Continuous cast iron straight pipe:
The continuous cast iron straight pipe is a continuously cast gray cast iron pipe, which is suitable for the transportation of pressure fluid such as water and gas.

4. Drained cast iron pipe:
Ordinary drainage cast iron sockets and fittings. The flexible anti-vibration interface drains the cast iron straight pipe. The cast iron pipe is sealed by rubber ring and bolted, and has good flexibility and flexibility under internal water pressure. It can adapt to large axial displacement and lateral deflection, and is suitable for indoor drainage pipes of high-rise buildings, especially suitable for seismic zones. From the interface form, it can be divided into: W-type flexible cast iron drain pipe, B-type flexible cast iron drain pipe, and A-type flexible cast iron drain pipe.
