Creep and burst tests

AIRLESS ADVANCED

Model no. 1814
Tests on finished products

Professionally pressure tested

The purpose of this tester is to apply and maintain the correct hydrostatic pressure for internal pressure creep tests. Bursting pressure tests can also be optionally performed. The internal pressure creep test is a test procedure for determining the strength of thermoplastic pipes when exposed to constant internal water pressure at a constant temperature. The samples are subjected to a defined and constant hydrostatic internal pressure for a specified period or until they fail. The load on the specimen is defined by the stress (by means of internal pressure) and the temperature. The testing device (base unit) has a modular design and can be equipped with up to 45 test stations. The test device is supplied with the required high-pressure water via the integrated pressurised water supply or a pressurised water supply from existing racks (base or expansion units).

Features and Functionality

A maximum of nine airless modules can be installed in the 1814 installation frame. A maximum of 45 test stations for time-dependent pressure tests or 12 test stations for burst pressure tests can be installed.

Up to four extension cabinets (without their own pressurised water supply) can be connected to the installation frame. The configuration varies depending on requirements, with a maximum of up to 60 test stations per extension rack for internal pressure tests or a maximum of 16 test stations for burst pressure tests.

In addition to the modules, the rack contains the pressurised water supply for generating the pre-pressure, the power supply and a status display.

Pressurised water supply

The pipe tester is supplied with the required high-pressure water via the integrated pressurised water supply (6, 12 or 24 litres/min.) or a pressurised water supply from existing frames (base or expansion units). The pressurised water supply consists of:

Water inlet with water filter and pre-pressure monitoring
Pressure vessel (buffer tank): Prevents pressure peaks and temporarily increases the water supply capacity.
Controller: For controlling the high-pressure pump and monitoring the system pressure.

Module and controller

For each module, a controller (microprocessor control) individually controls and regulates the pressure of the individual stations. For pressure control, each station has two solenoid valves and a pressure transducer. The solenoid valve MV1 regulates the pressure build-up. The solenoid valve MV2 is used for pressure reduction and pressure relief at the end of the test.

Options

Precision pressure measurement instrument 1817 (master gauge): An external precision pressure measurement instrument can be connected via a needle valve bar in order to check the test pressure before or during a test. The test pressures of the individual stations can be easily checked with the master gauge. They can then be readjusted if necessary if a pressure measurement accuracy of 0.3% of the final value of the pressure transducer does not appear to be sufficient.
