The internal pressure creep test is a test procedure for determining the strength of thermoplastic pipes. The samples are subjected
to a constant hydrostatic internal pressure at a constant ambient temperature either for a speciﬁed period or until they fail. The test
duration is subject to the tension generated by the internal pressure and the temperature. The IPT test tanks are specially designed
for testing thermoplastic pipes and ﬁttings. The high reliability, durability of the materials used and the constant temperatures in
the test tank 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.
