Hydrostatic testing is a core method for testing the sealing performance of GRP/FRP pipes. Traditional equipment has problems such as incomplete water injection, slow drainage, and air resistance affecting test results. The GRP/FRP Pipe Hydrostatic Tester developed by Lianyungang Tuotian Aviation takes "efficient water system synergy + air resistance elimination" as its core, integrates water injection, exhaust, and drainage systems, improves the efficiency and accuracy of GRP/FRP pipe hydrostatic testing, and becomes a key testing equipment in batch production.

The core highlight of the equipment lies in "water system optimization and air resistance elimination": The water injection system adopts a dual-channel water injection design, with the main channel responsible for rapid water injection and the auxiliary channel for exhaust at the top of the pipeline. The water injection rate is automatically adjusted according to the pipeline volume, and it only takes 5 minutes to fill a DN2000mm pipeline with water; The exhaust system is equipped with a liquid level sensor, and when water flows out of the exhaust valve continuously for 30 seconds, it is determined that the pipeline is fully filled without air resistance, and the exhaust valve and water injection pump are automatically closed to avoid pressure test errors caused by air resistance. The drainage system adopts negative pressure drainage technology, and the accumulated water in the pipeline can be drained within 2 minutes after pressure testing, which is 4 times more efficient than gravity drainage and reduces the waiting time for pipeline reset.

The operation process is highly automated: After inputting the GRP/FRP pipe diameter, test pressure, and pressure holding time, the equipment automatically starts the water injection-exhaust-pressure application-pressure holding-drainage process; During the pressure holding stage, pressure changes are monitored in real time, and a qualification certificate with hydrostatic curves is automatically printed if there is no leakage; After drainage, the bracket automatically resets to facilitate the hoisting of the next pipe, and the single test cycle is 30% shorter than that of traditional equipment. The equipment's water system is equipped with filtering and softening devices to prevent impurities or calcium and magnesium ions in water from depositing on the inner wall of the pipeline or inside the equipment, extending the equipment service life and ensuring testing accuracy.
