Cast pipes are cast in 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. The flexible interface is sealed with a rubber ring. The nominal diameter of the continuous gray cast iron pipe is 75-1200 mm, and it is in the form of a socket-type or flanged-plate interface. According to the function, it can be divided into a flexible interface and a rigid interface. The length of the straight pipe is 4 meters, 5 meters and 6 meters; according to the wall thickness, they are divided into three levels: LA, A and B. Sand type centrifugal gray cast iron pipe nominal diameter of 200 ~ 1000 mm, effective length of 5 meters and 6 meters; according to different wall thickness points P, G two levels. High strength, good toughness, thin wall, small amount of metal, can withstand high pressure, ductile iron pipe and gray cast iron pipe, high strength, good toughness, thin wall, less metal, can withstand Higher pressure, effective length of 5 meters and 6 meters; according to different wall thickness points P, G two. Is the development direction of cast iron pipe.
Liaocheng Hongfu Pipe Co., Ltd. is a professional sales ductile iron pipe, seamless steel pipe, high pressure boiler pipe, high pressure alloy pipe, square pipe manufacturers, to understand the latest ductile iron pipe prices, seamless steel pipe prices, high pressure boiler pipe prices on the advice .
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.
