The properties of the products
Light weight
The weight per unit is only 1/6 of the cast-iron pipes, so the transport is quite convenient.
High strength
The strength can get to 45mpa
Low resistance
The internal surface of the pipe is smooth with no dirt and no blockage. The loss is 30% lower than that of the cast-iron pipes.
Corrosion resistance
It has good quality of high acid resistance, alkali resistance, chemicals resistance and electrochemistry resistance, so the point of corrosion will not occur during the use.
Easy installation
It adopts the glue and soft joining. Therefore, the installation is quite easy and sealing is reliable.
Long service life
The service time can reach more than 50 years under the normal working pressure.
Low cost
The cost of transport and installation is low, and the total engineering cost is 30-40% lower than of the cast-iron pipes.
Non-toxic and sanitation
The product conforms to the standards of the drink water and water transported has no second pollution.
