Pipe Hydrostatic Pressure Testing Machine

Overview

1. Core Functionality

   This instrument is designed to conduct long-term internal pressure resistance tests on pipes or fittings within a specified pressure range. It automatically stops upon sample rupture or test completion, saves pressure curves, and prints test reports. Pressure regulation is achieved via solenoid valves for pressure compensation and release: precise pressure stability is maintained through intermittent activation of these valves. Key features include automatic constant pressure, electric pressure relief, flushing, and automatic calibration.

   Imported U.S.-made solenoid valves and a unique sealing structure ensure long-term sealing perbance and durability (when using clean water). To mitigate risks from sudden power outages or computer failures, the pressure host unit provides long-term data storage and download functionality, reducing operational workload. It is an economical, versatile, and highly automated testing solution.

2. System Comb

   • Pressure Host: Integrates micro-control, automatic pressure compensation, and electric pressure relief modules. Utilizes a microcomputer control system with high-resolution, high-speed computing modules for real-time communication with computers, enabling automatic pressure adjustment.

   • Pressure Station: Supplies stable pressure to the host (output pressure must exceed the maximum test pressure requirement). Equipped with an imported U.S. plunger pump—featuring high flow rate, low noise, high pressure, and maintenance-free operation. Automatic water replenishment via external high-pressure hoses ensures reliable pressure sourcing.

   • Water Tank: Comprises circulation, heating, automatic water replenishment, and insulation sections. A high-flow pipeline pump ensures unib temperature distribution and rapid heat exchange.

   • Temperature Control System: Precisely regulates and displays water temperature, allows independent temperature setting, and intelligently controls liquid levels to balance thermal stability and safe filling levels.

   • Software System: Connects to the pressure host via an RS232 serial interface, offering beter configuration, calibration, pressure relief, zero adjustment, amplitude adjustment, real-time test curve plotting, data logging, and report printing.

3. Application Fields

   Widely used for hydrostatic pressure testing of plastic pipes, this machine is ideal for building material manufacturers, pipe producers, national inspection agencies, and research institutions. Its intermittent pressure compensation ensures exceptional pressure stability and high flow rates, meeting test requirements for pipes of all diameters. It fully replaces imported equipment, offering simple operation and superior perbance. Exported bly with proven reliability, it is a critical tool for buating pipe pressure resistance under constant internal pressure and temperature—essential for production, quality control, and R&D of plastic/composite pipes.
