    End Closure For Plastic Pipes engineered for sealing pipe samples during hydrostatic fluid and bursting pressure testing



    Summary:

    The DN450mm high-pressure end caps, tailored for hydrostatic and bursting tests, are engineered and fabricated specifically to support internal hydrostatic pressure and bursting performance evaluations of pipes and pipe fittings. These specialized components deliver reliable airtight sealing for test specimens, enabling the controlled buildup of internal pressure required to complete rigorous hydrostatic and bursting test procedures.


    Structural composition:

    This Casting A-type structural fixture adopts a rod-free intermediate configuration, endowing it with superior pressure-bearing capacity to withstand ultra-high test pressures.

    The fixture is composed of a suite of precision-engineered components, including a semi-circular base, an O-type silicone rubber sealing ring, a pressure ring, a fastening clamp, fastening bolts, compression bolts, and a vent valve. Each part works in tandem to ensure airtight sealing and stable structural performance during high-pressure testing procedures.


    Application:

    These specialized DN450mm high-pressure end caps, engineered for hydrostatic and bursting tests, are typically deployed to seal pipe specimens of PVC, PE, PP-R, ABS, and composite materials. They facilitate a wide range of pressure-based performance assessments, including hydrostatic pressure tests, bursting strength tests, and negative pressure tests.


    Standards:

    GB/T 6111, GB/T 18252, GB/T 15560, etc and EN921, ISO1167, ASTM D 1598/1599,

    FAQ:

    Q1: What is the maximum pressure resistance rating of the fixtures for pipe hydrostatic testing machines?

    A1: The fixtures are engineered with a robust structural design to withstand ultra-high test pressures, with a maximum pressure resistance of up to 20 MPa (200 bar). This performance enables them to support rigorous bursting tests and long-term hydrostatic pressure tests for high-strength pipe materials such as PE and composite pipes.

    Q2: What range of pipe diameters can these hydrostatic testing fixtures accommodate?

    A2: The fixtures offer broad compatibility with pipe diameters ranging from DN20 to DN450, covering most common specifications of plastic pipes, composite pipes, and pipe fittings. Customized fixture sizes can also be provided to match non-standard pipe dimensions.

    Q3: What material is used for the sealing components of the fixtures, and what is their temperature resistance range?

    A3: The sealing components adopt high-performance O-type silicone rubber sealing rings, which can maintain excellent airtightness within a temperature range of 15–95℃. For high-temperature testing scenarios, fluororubber sealing rings can be customized to withstand temperatures up to 150℃.

    Q4: What structural features do the fixtures have to ensure stable performance during testing?

    A4: The fixtures adopt a casting A-type rod-free structure, eliminating intermediate tie rods that may cause stress concentration. They are assembled with precision components including pressure rings, fastening clamps, and vent valves, which not only enhance pressure resistance but also ensure uniform force application to avoid specimen deformation during testing.

    Q5: How long does it take to install and disassemble the fixtures, and is the operation process convenient?

    A5: The fixtures are designed with a quick-release fastening bolt system, which allows a single operator to complete the installation and disassembly of a pipe specimen within 3–5 minutes. The integrated vent valve also simplifies the air exhaust process before testing, effectively improving the overall testing efficiency.

    Q6: Do the fixtures comply with international testing standards, and what types of tests are they applicable to?

    A6: The fixtures fully comply with ISO, ASTM, and GB standards for pipe hydrostatic testing. They are applicable to a variety of test types, including internal hydrostatic pressure tests, bursting strength tests, long-term pressure endurance tests, and negative pressure tests for PVC, PE, PP-R, ABS, and composite pipe specimens.
