Abstract
An apparatus for testing the tightness of liquid-conducting tubes, connected with a pressure generator and an expansion chamber provided with a gas cushion separated from the liquid by a membrane and which can be pre-stressed at a test pressure, characterized because the expansion chamber consists of a conventional expansion vessel that can be connected to a network of water-conducting pipes for, for example, a heating boiler, whose gas cushion, completely enclosed, with a constant amount of gas, can be compressed on the water side under static pressure.
