GB PVC FITTING COMPRESSION COUPLING FOR WATER SUPPLY
What is the function of the pvc compressiong coupling?
1. Compensate the expansion deformation of absorption pipeline caused by axial, transverse and angular heating.
2. Absorbing equipment vibration, reducing the influence of equipment vibration on pipeline.
3. Absorbing the deformation of pipeline caused by earthquake and subsidence.
But the main purpose of the pvc compressiong coupling used in PVC water supply pipe is to facilitate installation.
What are the characteristics of expansion joints?
1. Corrosion resistance, long service life
2. High pressure, shock resistance, easy installation
3. No odor, health, non-toxic, lead-free salt hygienic type
