Overview

One rig, two pressure regimes.

Submarine and naval-ship pipe assemblies have to survive both static hydraulic loading and gaseous pneumatic pressurization before they ever go to sea. The High Pressure Air Test System qualifies both in a single, purpose-built rig.

The High Pressure Air Test System is a dual-mode pneumatic test bench built to verify the mechanical strength, sealing integrity, and pressure endurance of critical piping components used in submarines, naval vessels, and marine infrastructure. It qualifies pipes and fittings before deployment in submarines, naval ships, offshore structures, and underwater energy systems.

The system supports both hydraulic and pneumatic testing regimes on a single platform, offering a complete validation path for metallic pipe assemblies and fittings used in high pressure pneumatic systems, under static and dynamic pressure conditions that simulate the most demanding operational environments.

600 Bar hydraulic. 400 Bar pneumatic. One control system, automatic or manual.

Programmable test sequences, real-time DAS data monitoring, and multi-layer safety interlocks make this pneumatic test equipment suited to defence-grade pressure validation and high-risk underwater applications.

Testing Modules

Hydraulic & pneumatic, in one rig.

Two independent testing modules on a shared control and safety architecture.

MODULE · 01

Hydraulic Testing Module

Uses deionized water as the working fluid, generating 50–600 Bar through Haskel USA high-ratio pneumatic pumps that convert 8–10 Bar drive air into hydraulic force. Pressure is applied incrementally in staged steps, each held for a set duration, to assess resistance to burst and deformation under long-duration static loads typical of deep-sea operation.

50–600 Bar · ~40 CFM

MODULE · 02

Pneumatic Testing Module

Uses clean, dry compressed air to simulate pressurization in gaseous environments, generating up to 400 Bar from a built-in compressor or high-pressure cylinder bank. Detects leakage, joint integrity, and structural behaviour under fluctuating or peak air pressures — critical for tees, elbows, and connectors in high-integrity marine systems.

20–400 Bar · ~80 CFM

Testing Sequences

Staged pressure ramp-up programs.

Every sequence is configurable through the automated test interface.

Hydraulic Testing Sequence

The hydraulic process runs a controlled multi-stage ramp: 50, 100, 150, 200, 250, 300, 400, and 600 Bar. Each intermediate pressure is held for approximately two minutes, and the maximum 600 Bar stage is maintained for ten minutes — replicating the extreme operating environments submarine and marine components must withstand.

Pneumatic Testing Programs

Program 1: 20, 100, 150 Bar — final stage held 10 minutes.
Program 2: 20, 100, 150, 200 Bar — 200 Bar stage held 10 minutes.
Program 3: 20, 100, 150, 200, 300, 400 Bar — 400 Bar stage held 10 minutes, others held 2 minutes each.

Modes of Operation

Automatic DAS or manual panel.

Every test can run unattended through the DAS or by direct operator control.

PC-based Data Acquisition System (DAS): selects test type, pressure levels, duration, and sequencing automatically.
Real-time monitoring: continuous tracking of pressure sensors, safety systems, and chamber status.
Digital logging: every test is recorded for traceability, certification, and reporting.
Remote video monitoring: live CCTV feed of the test chamber during active testing.
Automated safety: interlocks, threshold alarms, and automatic shutdown routines.

Front-panel control: toggle switches, potentiometers, and analog glycerin-filled gauges.
R&D-ready: ideal for prototyping and custom component trials.
Operator discretion: direct interaction with pressure stages and timing.
Manual safety: interlocks, manual emergency stop, and redundant monitoring.
Nitrogen purging: two 150 Bar N₂ banks remove moisture and contaminants from lines before and after pneumatic testing.

Safety & Core Components

Failsafe by construction.

Interlocked gate access, redundant pressure monitoring, and Haskel-class pump hardware.

Interlocked Gate

Electrically interlocked rolling gate ensures testing cannot commence unless the chamber is sealed.

410 Bar Relief Valves

Calibrated relief valves preset at 410 Bar protect both hydraulic and pneumatic circuits from overpressurization.

Redundant Monitoring

WIKA 0–600 Bar gauges and S-20 transmitters (0.25% FS accuracy) paired with digital and analog readouts.

Haskel USA Pumps

High-ratio pneumatic pumps convert 8–10 Bar drive air into up to 600 Bar hydraulic test pressure.

Key Features

Built for submarine-grade validation.

Dual-mode capability, redundant safety, and precision instrumentation in one system.

Dual-mode system tests marine pipes hydraulically (50–600 Bar, DI water) and pneumatically (20–400 Bar, dry air).
Haskel USA pumps with 8–10 Bar drive air generate up to 600 Bar for submarine and marine pipe assembly qualification.
Electrically interlocked gate, 410 Bar relief valves, and emergency vent valves ensure failsafe operator protection.
Nitrogen purging via two 150 Bar banks removes moisture and contaminants from lines before and after pneumatic testing.

WIKA 0–600 Bar gauges and S-20 transmitters (0.25% FS accuracy) paired with a Vaisala dew point meter ensure precision.
Redundant digital/analog pressure monitoring and live CCTV chamber feed keep operators safely outside during testing.
Three configurable pneumatic test programs support 20–400 Bar staging with each level held 2 or 10 minutes as needed.
Qualifies pipes, flanges, elbows, tees, and reducers for submarine, naval ship, and offshore energy system applications.
