Pressure Vessel Inspection & Compliance Services

Pressure vessels in Queensland must be inspected, certified, and registered to meet strict safety and compliance requirements. Black Square Engineering provides RPEQ-led pressure vessel inspection, certification, and compliance sign-off services for industrial operators, workshops, manufacturers, and asset owners across Queensland.

​

Whether you require certification for a new vessel, inspection for ongoing compliance, or support with registration and classification, we deliver practical, defensible engineering outcomes in accordance with AS 1210, AS 4343, and Queensland WHS legislation — ensuring your equipment is safe, compliant, and fit for service.

What We Inspect and Certify

Black Square Engineering provides a wide range of inspection and engineering support for a wide range of pressure equipment, including:

Our inspections are conducted by qualified engineers with a clear understanding of regulatory obligations and practical operational constraints.

Applicable Standards and Queensland Requirements

Pressure vessels in Queensland are subject to specific legislative and technical requirements. Our work typically references:

  • AS 1210 – Pressure Vessels

  • AS 4343 – Pressure Equipment – Hazard Levels

  • Queensland WHS Regulations for registrable plant

  • Manufacturer and design documentation requirements

We assist clients in understanding how these standards apply to their specific equipment and operational environment.

Inspection, Verification, and Certification — What’s the Difference?

Many SME operators are unclear on what level of engineering involvement is required. We help clarify:

Where required, inspections and reports are completed or reviewed by an RPEQ engineer to meet statutory expectations.

Client Responsibilities (What Stays With You)

While we provide engineering inspection and certification services, asset owners remain responsible for:

  • Ongoing maintenance and operation of equipment

  • Ensuring inspections are conducted at required intervals

  • Maintaining accurate records and documentation

  • Acting on recommendations identified in inspection reports

We aim to make these responsibilities clear so there are no surprises during audits or regulator engagement.

Pressure Vessel Inspection Across Queensland

We support clients throughout Queensland and across Australia, including remote and regional areas. Our work spans manufacturing, processing, construction, and asset-intensive operations where pressure equipment forms part of day-to-day operations.

Discuss Pressure Vessel Compliance Requirements

If you are unsure whether your pressure equipment requires inspection, certification, or registration — or if you are preparing for an audit or regulator review — we can assist.

Pressure Vessel FAQs

Does every pressure vessel need to be registered?​

 

Not every pressure vessel requires registration. Registration requirements depend on the type of vessel, its design, operating pressure, volume and the applicable workplace health and safety legislation in your state or territory.

​

Many compressed air receivers, pressure vessels and pressure equipment used in industry do require design registration, item registration, or both. Determining what applies can be complex, particularly for imported equipment or older installations.

​

Black Square Engineering can assess your pressure vessel against the relevant Australian Standards and legislation, identify any registration requirements, and guide you through the certification process.

How often should a pressure vessel be inspected?

Inspection intervals depend on the type of pressure vessel, how it is used and the level of risk associated with its operation.

In Australia, inspection frequencies are generally determined using AS 3788 – Pressure Equipment – In-service Inspection. This Standard provides guidance on inspection methods, inspection intervals and ongoing integrity assessment to ensure equipment remains safe to operate.

Regular inspections help identify corrosion, cracking, fatigue and other deterioration before they become safety risks or lead to costly unplanned downtime.

What is AS 3788 and why is it important?

AS 3788 is the Australian Standard that sets out the requirements for inspecting pressure equipment while it is in service.

Rather than specifying how a pressure vessel should be designed, AS 3788 focuses on maintaining its safety throughout its operating life. It provides guidance on inspection planning, risk assessment, testing methods and the competency of inspectors.

Following AS 3788 helps owners demonstrate that pressure equipment is being maintained appropriately and that ongoing operation remains safe and compliant.

Can an existing pressure vessel be certified?

Yes. Existing pressure vessels can often be assessed and certified, even if documentation is incomplete or the equipment has been operating for many years.

The assessment may include reviewing available design information, inspecting the vessel, verifying its condition and determining whether it continues to meet the relevant Australian Standards and legislative requirements.

This is particularly common for second-hand equipment, imported machinery, older industrial plant and pressure vessels that have changed ownership or location.

Do air receivers require pressure vessel inspections?

Compressed air receivers are one of the most common types of pressure vessels found in Australian workplaces and may require periodic inspection and registration depending on their size and operating conditions.

Although they are often overlooked because they operate quietly in the background, failure of an air receiver can have serious safety consequences. Regular inspection helps confirm the vessel remains structurally sound and continues to operate safely.

Black Square Engineering provides inspection, compliance assessment and certification services for compressed air receivers and other industrial pressure vessels across Australia.
