In the project support bracket installation related content and electrofusion pipe fittings test pressure commissioning methods and steps

Knowledge about how to install electrical dissolving pipe parts is available. Today's content is managed with strict closure, and the methods and steps related to you are described below. After removing the air from the pipe waiting to be tested, Winchester Electrolytic Pipe Fittings will raise the pressure to the desired pressure value at a steady rate of increase and the gauge should be placed as close as possible to the pipe at that level. The pressure test may be carried out either before or after the backfilling of the pipe, and the pipe should be overthrown with earth at regular intervals, especially in the case of serpentine pipes, which should be held in position during the pressure test. The connection area of the flange must be exposed to check for leaks.

The test pressure for the pressure test should not exceed 1.5 times the pressure level of the pipe or the pressure level of a component in the system with a low pressure level, but rather the pressure should be raised to a predetermined test pressure value. Taizhou electrofusion fittings company stay enough time to ensure that the tube is fully expanded, the trip needs 2-3h, after the system is stable, the pressure should be raised to 1.5 times the working pressure, an hour of pressure. Carefully observe the pressure gauge, patrol along the line, there will be no visible leakage or obvious pressure drop during the test, the tube passes the pressure test. In the pressure test process, the continuous expansion of the tube will to pressure drop, a certain pressure drop in the test process is normal, therefore, can not prove that the piping system does leakage or damage. Zhejiang electrofusion pipe fittings company due to the product in the daily use of the process of not encountered in the use of the situation and consumption problems, so your hand is necessary.
