Tests reinforced piping systems underwater for leaks.
The reinforced piping systems' connections are mounted and sealed on both sides in pressure testing devices. One pressure testing device is connected to the high pressure line,
then the sealed test specimen is placed on the grate of the submersible frame. The testing process is started via the capacitive start buttons. The lid closes and the specimen is subjected to the set test precompression to prevent the penetration of water into the specimen when the submersible frame is lowered into the water. The submersible frame is then lowered into the water and the specimen is subjected to the set testing pressure — the test sequence can be monitored on the control display. At the end of the test period, the specimen is vented and pressurized with the set test precompression. The submersible frame is then lifted out of the water; the specimen is completely deflated and the lid is opened. The pressure testing devices are loosened and the tested piping system is removed.
