Hydrostatic Pressure Testing Machine for Plastic Pipes ISO 1167 and ASTM D-1598 Compliant

Hydrostatic Pressure Testing Machine for PP-R, PP-B, PP-A, PVC, PE, PE-X Pipes

The Hydrostatic Pressure Testing Machine for PP-R, PP-B, PP-A, PVC, PE, PE-X Pipes is engineered in compliance with international standards including ISO 1167 and ASTM D-1598. It is primarily intended for testing plastic pipes and composite pipes, including PP-R, PP-B, PP-A, PVC, PE, PE-X, and more.

The machine supports two core testing modes:

• Applying a specified constant hydrostatic pressure to the pipe and maintaining it for a predefined duration (per test requirements);
• Applying a constant, rapid hydraulic pressure inside the pipe to induce specimen rupture within a short timeframe, followed by measuring the maximum pressure and subsequently calculating the ring stress.

• Pressure Control System (Main Unit);
• Pressure Supply System (Pressure Source);
• Test Tank and Temperature Control System;
• End Closures: φ20~110mm (customizable per customer requirements);
• Refrigeration System (optional per customer requirements)

Features of the Main Frame

• Adopts a computer-controlled mode, featuring high intelligence. It enables real-time monitoring, automatically records pressure and time, and offers user-friendly operation with high reliability.
• Supports continuous operation to ensure the completion of full-cycle tests; each independent sub-station is designed for easy operation and maintenance.
• Key components of the testing machine use imported brand-name parts, delivering enhanced stability and reliability.
• Tests can be operated via PC software or manually through the main unit's control panel, providing flexible operation options.
• Pressure-time curves are available for data visualization; real-time pressure value monitoring is supported for instant test status tracking.
• Test parameters can be set via the software, allowing unattended operation until the test is completed--reducing manual intervention and improving efficiency.

Features of the Constant-Temperature Tank

• The constant-temperature tank consists of the tank body, imported circulation pump, heating unit, and temperature maintenance system.
• The tank body comprises a structural frame, a base, a 304# stainless steel inner bladder, and an outer casing made of stainless steel or aluminum alloy--ensuring structural durability and corrosion resistance.
• Thick rigid polyurethane foam insulation is adopted, which effectively maintains temperature stability and delivers excellent energy efficiency, reducing unnecessary energy consumption during operation.
• The constant-temperature tank cover can be fitted with an automatic lifting and closing mechanism, providing reliable performance and operational convenience for daily testing workflows.

End Caps

• Material: 304# Stainless Steel or Carbon Steel
• Adopts a precision casting process, featuring an elegant and sleek appearance.
• Includes fully assembled components such as bolts, O-rings, and vent valves--no additional assembly is required on-site.
• All parts are easy to install, ensuring reliable sealing with no leakage. The design prioritizes user convenience for streamlined operation.
