The Critical Role of Pressure Relief Device (PRD) Inspections
In industrial environments, overpressure events can lead to catastrophic failures, equipment damage, and serious safety risks. Pressure Relief Devices (PRDs) — including Pressure Relief Valves (PRVs), Pressure Safety Valves (PSVs), and rupture discs — are your last line of defence.
To maintain compliance and protect people, plant, and equipment, these devices must be inspected and maintained in accordance with Australian Standards. According to Safe Work Australia, pressure equipment, including PRDs, must be regularly inspected to ensure equipment and workplace safety.
At AME, we deliver compliant PRD inspections and coordinate third-party testing through certified NATA laboratories, ensuring your PRDs operate reliably and meet regulatory requirements.
What We Offer
Visual Inspection & Assessment
Our experienced pressure vessel inspectors assess valve condition for signs of wear, corrosion, misalignment, or mechanical issues. Where concerns are identified, such as cracking or corrosion near the mounting area, we may recommend Non-Destructive Testing (NDT) to confirm asset integrity.
Calibration Checks
We verify that each valve's set pressure and operational responsiveness align with relevant standards and conform to design specifications.
Coordination of Certified Testing
We ensure all Safety Relief Devices meet strict NATA-accredited testing and certification requirements.
Types of Pressure Relief Devices We Inspect
Our team inspects a wide range of pressure relief devices commonly used in high-pressure systems across industrial sectors:
The most common type of pressure relief device, typically used in steam, gas, and air systems. These valves open automatically at a set pressure and reseat once normal conditions return.
Inspection focus: Seat wear, spring fatigue, corrosion signs, test tag damage and lift performance are checked to ensure proper function under pressure.
Engineered for high-pressure, high-capacity systems requiring precision and stability. These valves are ideal for fluctuating process conditions or where tight shut-off is essential.
Inspection focus: Pilot control lines, set point accuracy, and responsiveness are evaluated—often under simulated pressure scenarios.
Dual-function devices found in hot water, boiler, and steam systems. These protect against both excessive pressure and temperature by releasing fluid when thresholds are exceeded.
Inspection focus: Temperature sensors, discharge piping, and valve seat condition are assessed to confirm full operational readiness.
Designed for applications with variable or high backpressure. A bellows structure offsets the impact of backpressure to maintain accurate and consistent set pressure.
Inspection focus: Bellows integrity, spring chamber condition, and signs of leakage or fatigue are thoroughly examined.
A cost-effective option for standard industrial systems with minimal backpressure. These are commonly used where conditions remain relatively stable.
Inspection focus: Valve body condition, spring tension, and calibration accuracy are checked, especially in older systems.
Single-use safety devices that provide instant, full-opening relief. Ideal for systems handling corrosive media or where zero leakage is required.
Inspection focus: Proper installation orientation, disc material condition, and compatibility with current system pressures are verified (if not already activated).
Not sure what type of valve you have? Our inspectors can identify the device type and assess condition on-site to provide the required support.
High-Quality PRVs and Pressure Gauges Available from AME
In addition to our inspection and compliance services, AME supplies a wide range of high-quality pressure relief valves and pressure gauges for industrial applications. Whether you’re replacing aging components or upgrading to meet compliance standards, our product range is selected for reliability, durability, and compatibility with Australian Standards.
Pressure Relief Valves (PRVs)
Our PRVs are engineered to deliver reliable overpressure protection in demanding industrial environments. Manufactured for precision and durability, they respond rapidly to pressure spikes to safeguard your plant, equipment, and personnel. Whether you’re operating steam, gas, liquid, or mixed-phase systems, our valves help ensure regulatory compliance, minimise unplanned downtime, and extend the operational life of your pressure equipment. All PRVs supplied by AME are compatible with Australian Standards and can be integrated into your ongoing maintenance and inspection program.
Pressure Gauges
Accurate pressure monitoring is critical for both safety and system efficiency. We offer gauges suitable for high-pressure, corrosive, or vibration-prone environments. Not sure which valve or gauge is right for your setup? Our technical team can assist in selecting and supplying the right components as part of your inspection or maintenance plan.
Why PRD Inspection Matters
Regular inspection of PRVs, PSVs, and other PRDs helps you:
- Optimise safety outcomes in your workplace
- Meet standard compliance and legal obligations under AS 3788;2024 and AS 1271:2003
- Satisfy insurance and audit requirements
- Reduce risk in high-pressure environments
- Prevent common failures like corrosion, seat wear, sticking, or fatigue
