What are the standards for FRP pipes?
As the glass tube between the use of double "O" type sealing ring way to connect, so each installation of a pipe, at the socket to suppress, in order to detect double "O" type sealing ring sealing effect.
To install FRP pipes, first check the radial deflection of the GRP pipe. In accordance with the requirements of the specification, the FRP pipe shall be tested within 24 hours after the completion of the installation to test whether the initial radial deflection of the pipe installed is deformed and whether the pipe has occurred in the case of bulge, flat and other mutations.
In order to comprehensively check the installation quality of the pipeline, it is necessary to carry out a comprehensive examination according to the test methods stipulated in the code for construction and acceptance of water supply and drainage pipeline works and to carry out the water pressure test. Permissible water seepage can be carried out according to the standard of FRP pipe.
The pressure test pump passes directly through the test hole on the top of the pipe. The water pressure of the pipeline working pressure of 1.5 times after the pump stops (during the operation to open the drain valve exhaust), observation of 2min, the pressure drop value does not exceed the test pressure and the nozzle 5%, no leakage, nozzle pressure test is qualified. If the pressure drop is relatively fast, it shows the sealing effect is not good, to re install, to ensure that the FRP pipe pressure test system overall success.
