New Multi-Station Hydrostatic Pressure Test System Realizes Batch Rapid Detection for Mixed PP, PVC, PC Drainage Pipe Sp
A domestic precision testing instrument manufacturer has launched an upgraded computer-controlled hydrostatic pressure testing machine specially optimized for sewer pipe inspection, breaking the limitation that traditional equipment can only test a single material type in one batch. The new model supports simultaneous loading of PVC-U sewage pipes, PP gravity drainage pipes and PC high-strength industrial drain pipes, with independent closed-loop pressure control for each test station and real-time recording of pressure fluctuation, specimen burst time and crack generation data.
Different material characteristics are embedded in the system’s parameter library: rigid PVC pipes focus on instantaneous burst pressure values, PP pipes emphasize long-term creep failure time under constant pressure, while PC drainage pipes require high-temperature hydrostatic aging assessment to simulate underground high-soil-temperature environments. The equipment fully meets ASTM D1598 and GB/T 6111 test methods, greatly improving the detection efficiency of third-party quality inspection institutions and large pipe factories. At present, multiple municipal engineering quality supervision stations have placed bulk orders for the equipment to strengthen incoming inspection of buried drainage pipeline raw materials.
