The introduction of cast iron expansion
Cast iron expansion is also called the slip joint, expansion joint, compensator, expansion joint. Expansion in a certain range can be axial expansion, can overcome the pipe is not within an Angle of axial offset, can greatly convenient valve pipe installation and disassembly, free expansion in the pipeline allows expansion amount, once across its biggest ACTS as expansion amount limit, to ensure the safe operation of pipeline. Mainly to ensure the safe operation of the pipeline, and has the following functions: compensation Angle to the absorption pipeline axial, lateral, thermal deformation; Vibration absorption equipment, reduce equipment vibration influence on pipeline; Absorb the earthquake, subsidence deformation of pipeline.

Detailed information on cast iron expansion
1. Cast iron expansion for various water supply and drainage pipeline, water tower, water pump, water meter, valve installation conversion provides great convenience, for long distance pipeline due to temperature difference expansion has played a very good regulatory role.
2. Cast iron expansion pipe can be divided into cast iron (HT), copper (DT), galvanized (DX), brass (useful) and steel (SF) three. Work pressure points PN6, PN10, PN16 3 kinds.
3. The expansion pipe can choose cast iron, ductile cast iron, carbon steel.
4. Before the installation must loosen the pressure plate bolt, pull the product to install length, then tighten with diagonal method, and do not partial pressure, such as aerial is used, the corresponding fixed bracket must be installed on both ends.
5. The flange connecting the GB4216.3-4126.5 standard.

Cast iron expansion purposes
Cast iron expansion is pumps, valves, pipes and other devices connected to the pipeline of new products, connected by the bolt, making it a whole, and has certain displacement, convenient installation. Can withstand axial stress of pipeline. So you can at the time of installation and maintenance, according to the on-site installation size adjustment, at work, not only improve the work efficiency, and the cutting of pump, valve, pipeline equipment play a protective role.
