Dunstan Asset Integrity

Services — Pressure Vessel Inspection

Pressure vessel inspection, personally delivered.

Independent statutory and risk-based inspection of pressure vessels, air receivers, heat exchangers and boilers — undertaken by Senior AICIP In-Service Inspector Katie Dunstan, not delegated to junior inspectors or rotating contractors.

Every inspection is scoped against the vessel's design, service, damage mechanisms and operating history, and reported to satisfy both statutory obligations and the practical decisions that follow.

Statutory obligations, clearly understood.

AS/NZS 3788AS 4343WHS Regulations

Pressure vessels are registered plant under Australian work health and safety legislation. Owners are required to maintain registration, keep records current and have vessels inspected at the intervals appropriate to their hazard level under AS 4343 — before a vessel can legally return to service after repair, alteration or relocation.

Dunstan Asset Integrity carries out commissioning, recommissioning and periodic in-service inspections that satisfy these statutory requirements, with reporting structured so that compliance status, findings and required actions are unambiguous.

Compliance framework

  • Hazard level assessment to AS 4343

  • Inspection interval determination to AS/NZS 3788

  • Commissioning and recommissioning inspections

  • Registration and statutory documentation support

  • Repair and alteration return-to-service inspection

What a pressure vessel inspection covers.

Each inspection is planned around the vessel — its materials, service conditions and credible damage mechanisms — rather than a generic checklist. Internal and external examinations are combined with condition assessment techniques suited to the equipment.

Findings are reported with clear condition statements, photographic records and defensible recommendations for repair, continued operation or interval adjustment.

The engagement typically includes

  • Internal and external visual examination

  • Wall thickness measurement and corrosion assessment

  • Damage mechanism identification

  • Review of design, fabrication and repair records

  • Assessment of repairs, alterations and modifications

  • Condition report with statutory compliance statement

Inspection experience spans the pressure equipment found across mining, manufacturing, energy and heavy industry — from small air receivers through to large process vessels and boiler plant.

Typical equipment

  • Pressure vessels and process vessels

  • Air receivers and accumulators

  • Heat exchangers and tube bundles

  • Boilers and fired equipment

  • Pressure piping systems

  • Filters, separators and autoclaves

One inspector. One accountable opinion.
