The internal pressure creep test is a test procedure for determining the strength of thermoplastic pipes. The specimens are subjected to a constant hydrostatic internal pressure at a constant ambient temperature either for a specified period of time or until they fail. The test duration depends on the tension generated by the internal pressure and the temperature.

The IPT test baths are specially designed for testing thermoplastic pipes and fittings. The high reliability, durability of the materials used and the constant temperatures in the test bath with respect to both volume and time provide particularly reliable test conditions. The efficient use of energy with low servicing and maintenance costs guarantee efficient long-term operation. There are a wide range of tank dimensions and connection options, enabling the tanks to be flexibly adapted to various operating conditions.
A special circulation system, in conjunction with a high-precision temperature controller, ensures even temperature distribution throughout the entire tank and a temporal consistency of ± 0.3°C. All specimens are tested under the same conditions and with extremely low energy consumption – a matter of course for IPT.
IPT test baths are equipped with optional temperature protection and all electrical safety devices are equipped according to VDE provisions.
Use the dimensions of your specimens to determine the water depth and internal base area of your test bath. The standard models currently available, sorted by internal dimensions, can be found in the table opposite.
Even the tall tanks can be conveniently loaded thanks to recessed installation or stairs and platforms.
The variety of lid designs makes it possible to install the tanks even in rooms with a limited ceiling height.
The purpose of this tester is to apply and maintain the correct hydrostatic pressure for internal pressure creep tests.
For mid-level testing demands, the Airless Blue Line ensures pressure control at maximum adjustment precision and consistency.
