Product application:
Drinking water transportation:The inner surface of GRP pipes is clean and smooth, and it will not be polluted by microorganisms such as shellfish and fungi in the water, which will lead to rough surface, reduce excess water and increase maintenance costs.Long-term use of GRP pipes clean as before, will not cause pollution to the water quality, very suitable for the transportation of drinking water.

Product installation:
Underground FRP drinking water pipe installation:Ditching and excavation, pipe bedding’s compaction and backfill of the backfill material should meet the technique requirement of the installation of FRP pipe. To minimize the work volume of pipe connections on the spot and to lay out pipes rapidly, all the difficult connections should be put on by the factory. When the installation is finished, pipeline should be tested with water pressure in accordance with the guide of specifications for installation of underground FRP filament winding pipe issued by Zhongfu Lianzhong.
Performance Standards:
CHINA STANDARD :Currently there are several China Standards in use for GRP pipe, such as GB21238, JC552, CECS190, CECS129, which basically equivalent foreign standard. The performance and design and burying of GRP pipe are specified by these standard. Lianzhong participated in the formulating of these standards.
GB21238 | Fiberglass pipe with sand filler |
JC552 | Fiberglass pressure pipe |
CECS190 | Fiberglass pipe Design Manual |
CECS129 | Fiberglass pipe Installation & Inspection Manual |
