Glass fiber reinforced plastic sand pipe is a kind of equipment used in many pipeline projects. Sometimes, the length of pipe is not long enough, so it is necessary to connect two pipes. What are the concrete methods?
In general, when connecting glass fiber reinforced plastic sand pipes, there are three ways to use them: socket, butt joint and flange. Among them, the most commonly used connection method is socket, which is used for connecting underground pipes. Now many projects will use O type sealing ring connection, connection method of concrete is the use of two sealing rings connected in the socket with a pressure nozzle, the main function is to test the connection when the pressure, to prevent because of the pressure connection problems.
At the time of installation, the construction staff must pay attention to the pressure test mouth up, between the two aprons can. When an interface is completed, the construction personnel should perform pressure test, the amount of water used does not need too much, the duration is generally 3 to 5 minutes. In accordance with this step, each sealing ring is successfully installed, complete the whole glass fiber reinforced sand pipe connection work.
