Plastic Pipe Hydrostatic Pressure Burst Tester

The Plastic Pipe Hydrostatic Pressure Burst Tester utilizes an international airless pressure control system. Its core is a dual-CPU control system (computer and instrument) with the same pressure control method as used in Denmark. It employs differential pressure control technology to independently control each test circuit, ensuring mutual independence and no interference. It can simultaneously perform various tests with different pressures and durations. It is suitable for long-term hydrostatic pressure tests, instantaneous burst tests, and thermal stability 8760 tests on various materials and pipe diameters, including PVC, PE, and PP-R.

Applications

The Plastic Pipe Hydrostatic Pressure Burst Tester is suitable for hydrostatic pressure burst testing of PVC, PE, aluminum-plastic composite pipes, and other similar materials. Based on the fundamental principles of material mechanics and fluid mechanics, it simulates the pressure conditions that pipes may experience in real-world applications by applying gradually increasing pressure to the inside of the pipe, thereby evaluating the pressure resistance and safety performance of the pipe. It features both computer and manual control, and is equipped with a constant temperature water tank for automatic temperature control. This testing machine fully complies with relevant national standards and can be customized according to specific requirements. During the test, pressure changes, test time, and other data can be monitored in real-time through the data display interface on the LCD screen. Simultaneously, the deformation of the pipe and any other abnormal conditions should be closely observed.

Test Procedures

1. Pre-test Preparation

Check the equipment power supply (matching the equipment voltage requirements) and the supply of test medium (usually deionized water), and confirm that there are no leaks in the equipment piping;

Calibrate the pressure sensor and temperature sensor (refer to the equipment calibration certificate, or verify using standard calibration equipment);

Connect the TCP/IP data connection cable to ensure normal communication between the equipment and the laboratory network (if remote monitoring/data synchronization is required).

2. Sample Preparation

Cut plastic pipe samples according to ASTM D1598 standard requirements (usually the length is 5-10 times the pipe diameter, and defects at the ends of the pipe must be removed);

Measure the pipe diameter and average wall thickness of the sample using a vernier caliper and wall thickness gauge, and record the basic parameters of the sample.

3. Sample Installation

Select the corresponding specifications of clamps and sealing components according to the sample pipe diameter;

Connect both ends of the sample to the sealing components and fix them in the clamps of the test chamber, ensuring that there is no medium leakage at the sealing parts (low-pressure medium can be pre-injected to check the sealing performance).

4. Test Parameter Settings

Select the test standard (e.g., "ASTM D1598") through the equipment's microprocessor controller;

Set the test parameters: target hydrostatic pressure, test medium temperature, and maximum test duration (or select "burst test mode");

Enable the "real-time data synchronization" function to ensure that test data can be transmitted to the laboratory network.

5. Starting the Test

Start the equipment's medium injection and pressurization program. The equipment will automatically inject the medium into the sample and pressurize it to the set value;

During the test, monitor the pressure, temperature, and sample status in real time through the controller interface or network terminal.

6. Test Monitoring and Termination

If the sample bursts, the equipment automatically records the burst pressure and failure time, and the test terminates;

If the sample does not fail after the set duration, the equipment records the pressure holding time and final pressure, and the test is stopped manually.

7. Post-test Processing

Slowly release the pressure in the test chamber and remove the tested sample (record the sample failure mode, such as burst location and crack morphology);

Clean the test chamber and piping, and drain the residual medium;

Export the test data (local storage + network backup) and generate a test report.
