Advantage:

1. Light weight, easy to transport and install. New generation of environmentally friendly modified
PVC-U plastic well casing with specific gravity of 1.35-1.45, only accounting for 1/6 or so of
steel pipe and cast iron pipe. In the process of well completion. The weight of the well casings
going down well is about more than the mud buoyancy, so that well casings may be transported
down well smoothly without the need of large lifting force. Well casing installation is safe and
reliable and labor intensity required is less for transporting well casings down.
2. Excellent corrosion resistance and durability. New generation environmentally friendly modified
PVC-U plastic well casing almost does not react with acid, alkali, salt and other chemicals, and
the service life is more than 50 years;
3. A high degree of water quality assurance. New generation environmentally friendly modified
PVC-U plastic well casings are made of health-class PVC-U plastic pipes, and are health, nontoxic, non-scaling, no breeding of bacteria and no water quality pollution.
4. Reduced energy consumption. The roughness of new generation environmentally friendly
modified PVC-U plastic well casings is only 0.008. With smooth wall, the energy consumption in
the process of using is less. Tension of wire to be connected will be determined;
5. Excellent anti-rupture strength and shock resistance. Pipe ring rigidity of new generation
environmentally friendly modified PVC-U plastic well casings > 32000N / m2.
6. Wear resistance. New generation environmentally friendly modified PVC-U plastic well casings
have excellent wear resistance, and can greatly reduce the wear of filter clearance due to water
inflow;
7. Well casing connection is simple, safe and reliable. New generation environmentally friendly
modified PVC-U plastic well casings adopt specific thread or shear pin connection and have high
tensile strength, greatly saving casing installation time;
8. Cheap well casing spacing and low cost of well building. Compared with the steel well casings
of same specifications, the price of new generation environmentally friendly modified PVC-U plastic
well casings is 1/3 lower than that of steel well casings. In addition, finished well casings are
featured by light weight, thus the transportation costs can be substantially reduced: convenient
well casing installation and handling, great of well completion
