Testing the pressure resistance of resin pipes is crucial for ensuring their safe and reliable operation under high-pressure conditions. It is typically conducted through hydrostatic or pneumatic testing, with hydrostatic testing being the preferred method due to its higher safety and more accurate reflection of the pipe's pressure-bearing capacity in liquid media.
Pre-Test Preparation Requirements
Environment and Equipment Inspection
The testing area should be well-ventilated, away from fire sources, and ensure operational safety.
Check the pressure source (e.g., water pump), pressure gauge, connecting pipes, and sealing devices for integrity to avoid the risk of leakage or pipe burst during testing.
Pressure Gauge Selection Specifications
The pressure gauge accuracy should not be lower than 1.5, the range should be 1.3 to 1.5 times the test pressure, and the dial diameter is recommended to be no less than 150 mm for accurate readings.
It is recommended to use a pressure gauge with metrological certification to ensure data traceability.
Pipeline Pretreatment
After filling the resin pipe section with water, soak it thoroughly for at least 12 hours to eliminate the influence of water absorption by the pipe wall on the test results.
Water filling should be done slowly, and the air vent valve should be opened to completely expel air from the pipe, preventing air pockets from causing pressure fluctuations or misjudgments.
