ductile Cast iron pipe connection method
Mar 28, 2018

 ductile Cast iron pipe,  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.

Cast iron pipe connection method:

The connection between the pipe and the pipe adopts socket type or flange type interface; according to the function, it can be divided into two kinds: flexible interface and rigid interface. The flexible interface is sealed with a rubber ring, allowing a certain degree of rotation and displacement, so it has good shock resistance and tightness. It is simpler and quicker to install than a rigid interface, and it is labor-intensive according to different casting methods.
