How to Conduct Hydrostatic Pressure Tests on Plastic Pipes?

Plastic pipe testing can be a cumbersome and complicated process, especially if your product caters to an international market with tough regulations. Hydrostatic pressure testing on plastic pipes is a common requirement among many manufacturers and governments we partner with. Over the years, Qualitest has developed advanced machinery to determine the resistance of thermoplastic pipes intended for the conveyance of fluids. Our machines conform to ASTM D1598-2004, ASTM D1599 and IS0 1167-2006 standards.

If plastic pipes are not made properly, hydrostatic pressure can cause them to burst. To determine the resistance of thermoplastic pipes, a hydrostatic pressure testing system subjects the pipes to constant internal water pressure at a constant temperature. Qualitest's Hydrostatic Pressure Tester provides user-friendly and accurate results to test the strength of thermoplastic pipes.

Qualitest's Hydrostatic Pressure Tester stands out from the competition with its state-of-the-art pressure control unit. Here are a few key features:

Pressure Control Unit

  • Pressure control unit comes with a touch screen or PC for test parameter settings. Testing results are easy to convert to Excel for further processing.
  • Supply up to 50 different pressures on the area less than 1m2.
  • Specimen size and material intelligent identification comes with optimized pressure rising solution and algorithm.
  • High accuracy pressure control. Selectively adjustable input pressure in each individual module to reduce the wearing of solenoid valves.
  • All metal components that come into contact with the medium are made of high-quality stainless steel.
  • User friendly, multi-languages interfaces are provided for different users.
  • Quick calibration. Pressure calibration and temperature calibration can be run during the test.
  • Individual circulation time, flow rate and pressure can be selected.
  • It provides the test constancy as regards to temperature, pressure and flow rate as well as lowering the energy.
  • Reliable safeguards, e.g. liquid level measuring devices, emergency stop and cord switch ensure the tester is out of action in case the test fails or piping system bursts. Doors shall be locked during the testing period.
  • Reliable data exchange via TCP/IP protocol.

Thermal Tank

  •  Optimal material selection. Inner container, outer protection plate as well as the lid are made of high quality stainless steel. Further, all the components that come in contact with medium are also made of high-quality stainless steel.
  • Thermal Tank is constructed with the heavy section steel frame providing an extremely rigid performance.
  • Optimized heating capacity and excellent thermal insulation reduced energy consumption rate. Even when the water temperature reaches 95℃, the outer cover will still stay at room temperature. It helps to enhance the security and save more than 70% of power consumption.
  • Unique steam collection device keeps steam and heat in the test tank and protects against injury.
  • Automatic water filling design ensures full tank capacity during the whole time.
  • Lids are opened by hydraulics and opening degree can be adjusted up depending on operator’s requirements.
  • Quick couplings simplify the connection of the test specimens.
  • Outer protection plates can be removed to access serviceable parts such as circulation pumps, heating elements etc. Service and maintenance can be performed when the tank is filled with water due to the unique design.

Endcaps

By using the advanced structure, Endcaps are particularly rapid to assemble and disassemble without any special tools even on chamfered and oval pipes. The hollow-out design has reduced the weight drastically compared to the standard Endcaps and it is easier for observation and operation. They are manufactured with anti-corrosive materials and fit regardless of the pipe wall thickness.
