| As a pipe fittings, in order to apply the gas, water and chemicals as the media vacuum, low pressure piping system has the following four basic functions:  Bad noise can be reduced due to the pipe material movement, force generated. You can reduce or isolate vibrations from the pump, fan and other large rotating devices produced; It can absorb axial, radial from the pump, air compressor, fan and piping, and other related equipment due to external force of displacement and distortion; It can be absorbed due to temperature changes, piping pulsation caused by the deformation of the axial displacement;  |
