Hydrostatic Pressure testing equipment is used for checking internal pressure in HDPE, PVC, PPR, CPVC pipes ranging between 16 mm diameter to 400 mm diameter. As per IS 4984 and IS 4985 to check the creep rupture of pipe when subjected to internal pressure under a specified condition.
International Equipments is a leading manufacturer, supplier and exporter of Computerised Hydrostatic Pressure Testing Equipment in India. Built at our Mumbai facility and exported to plastic pipe manufacturers across India, the Middle East, Africa, South-East Asia and Europe, our Hydrostatic Pressure Testing Equipment is the dedicated control panel for long-term internal pressure testing of HDPE, PVC, PPR and CPVC pipes — strictly as per IS 4984, IS 4985, ISO 1167 and ASTM D 1598.
Hydrostatic pressure testing — also called creep rupture testing or pipe burst testing — is the single most important QC test for any pressure-rated plastic pipe. It directly measures how long the pipe survives at design pressure and temperature, predicting the 25-year, 50-year or 100-year service life of the finished pipe. A pipe that fails the hydrostatic test will leak or burst in service well before its rated lifetime; a pipe that passes will deliver its designed service life. The Computerised Hydrostatic Pressure Testing Equipment is the control panel that runs this critical long-duration test across 8 pipe samples in parallel, with full data logging through MMI and PC.

Hydrostatic Pressure Testing is the laboratory test in which a length of plastic pipe is sealed at both ends, filled with water, pressurised to a specified percentage of its design pressure, and held at a controlled elevated temperature for hours, days, weeks or up to 10,000 hours — depending on the specific test point being established. The pipe sample either survives the full test duration (a pass) or fails by leaking, ballooning or bursting at some point during the test (a fail). The time-to-failure data at multiple pressure-temperature combinations is then used to plot the long-term hydrostatic strength curve of the pipe material.
The technical name for this failure mechanism is creep rupture — the slow time-dependent fracture of a polymer subjected to sustained internal pressure. Different from a short-term burst test (which gives the immediate burst pressure in seconds), creep rupture testing reveals what happens over weeks, months and years of pressure loading. This is why hydrostatic pressure testing is the only laboratory method that can reliably predict the actual service life of a plastic water, gas or chemical pipe.
Our Computerised Hydrostatic Pressure Testing Equipment is the dedicated control panel that holds 8 pipe samples at independently controlled set pressures, set temperatures and set times — all running in parallel for maximum laboratory throughput. The pressure range is 0 to 100 bar (with other capacities available on request), which comfortably covers the test pressures specified by IS 4984 (HDPE), IS 4985 (uPVC), IS 14333 (HDPE sewerage), IS 15778 (CPVC) and the related international standards.
Compressed air supplied by the customer's compressor (up to 5 kg/cm²) is the input to a hydro-pneumatic pump inside the panel — which generates the much higher water pressure (0–100 bar) applied to the pipe samples. The hydro-pneumatic conversion is essential because plastic pipes are pressurised with water (not air, for safety reasons — a water-pressurised pipe that bursts releases far less energy than an air-pressurised one).
The time range of 0 to 999.9 hours covers all standard hydrostatic test points — from the short-term high-pressure test points (1–100 hours) right through to the long-term low-pressure points (up to ~42 days continuous testing). Trolley mounting with castor wheels lets the laboratory move the panel to the optimal position relative to the SS Tank — essential because the pipe samples sit in the heated water tank, and the panel feeds pressure to each station via flexible hoses.
Direct readout on the on-board MMI (Man-Machine Interface) shows set pressure, actual pressure, set time, actual time, set temperature and actual temperature for each station. PC connectivity adds graphical display — pressure-versus-time and temperature-versus-time graphs plotted for any station via a connected printer — giving the complete documented record needed for ISI mark certification, BIS audit and customer reporting.
The Hydrostatic Pressure Testing Panel is the central control unit — but it cannot operate in isolation. To run the actual test, the laboratory needs three components:
