What is cast iron pipe cast iron pipe connection

Cast iron pipe is one of our most common industrial-use pipelines. Its powerful production has brought us practicality, and many manufacturers are also constantly producing and manufacturing. It is an important product to connect all kinds of pipes. So what exactly is a cast iron pipe? What is the connection of cast iron pipes? Next let's take a comprehensive look.

What is cast iron pipe?

En877 Cast Iron Pipes, molded cast pipe with cast iron. Cast iron pipes are used for water supply, drainage and gas pipelines. They include straight cast iron 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, centrifugal iron pipe is divided into sand type and metal type. According to different materials, it can be divided into gray cast iron pipe and ductile cast iron pipe. According to the interface form, it is divided into flexible interface, flange interface, self-anchor interface, and rigid interface. Among them, the flexible cast iron pipe is sealed with a rubber ring; the flanged 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 large cast iron pipe socket, and after the straight pipe is inserted, it is sealed with cement. This process is now Basic elimination.

What is the connection of cast iron pipe?

Cast iron pipe connection method: Cast iron pipe generally adopts rigid interface and flexible interface. The rigid interface uses a ramie asbestos cement interface and a rubber ring expansion cement interface. The flexible interface uses an apron asbestos cement interface, ductile iron pipes are all flexible interfaces, and semi-rigid and flexible interfaces use hemp-lead interfaces.

What are the types of cast iron pipes?

1、Drainage cast iron pipe

Ordinary drain cast iron sockets and fittings. Flexible earthquake-resistant interface cast iron straight pipe, this kind of cast iron pipe adopts rubber ring seal and bolt fastening, which has good flexibility and flexibility under internal water pressure. It can adapt to large axial displacement and lateral deflection, suitable for high-rise building indoor drainage pipes, especially suitable for earthquake area. From the interface form can be divided into: W-type flexible cast iron drainage pipe, B-type flexible cast iron drainage pipe, A-type flexible cast iron drainage pipe.

2. Sand centrifugal cast iron straight pipe

The sand-type centrifugal cast iron straight pipe is made of gray cast iron and is suitable for conveying pressure fluids such as water and gas.

3, continuous cast iron straight pipe

The continuous cast iron straight pipe, that is, the continuously cast gray cast iron pipe, is suitable for the transportation of pressure fluid such as water and gas.

4, water supply cast iron pipe

After the cast iron pipe for water supply No. 18 or above is used, the cast iron is added with a nodulizer, and after the high-speed centrifugal casting of a ductile iron machine, the ductile iron pipe has the nature of iron and the properties of steel, and has excellent corrosion resistance, good ductility, and sealing. Good effect, easy installation, mainly used for municipal, industrial and mining enterprises, water supply, gas transmission, oil and so on. It is the first choice for water supply pipes and has a high price/performance ratio.
