Local Pressure Vessel Inspection and Recertification Company in Queensland
Pressure Vessels are containers that are designed to hold liquids, gases or vapors at pressures substantially different from the ambient pressure. They are often used in the storage and processing of oil and gas, petroleum products, the processing of chemicals, steam boilers, and engine cylinders.
What Industries Use Pressure Vessels?
The application for pressure vessels is quite varied. They are used for the oil and gas industry, energy, transportation, military, storage, mining, alternative fuels, chemical plants, aerospace and more. If you are in any of these industries and have concerns about the quality or current condition of your pressure vessels, then please contact us on 0447 624 929 or use our online form.
What is involved with Pressure Vessel Inspection?
The pressure vessel is manufactured in accordance to local and international standards such as AS4544 Pressure equipment—Manufacture and / or ASME VIII Rules for Construction of Pressure Vessels. The inspection we do is carried out according with in-service pressure requirements AS/NZS3788 Pressure Equipment – In-service inspection and / or API510 Pressure Vessel Inspection Code: Maintenance, Inspection, Rating, Repair, and Alteration .
It is the owner’s responsibility to ensure safe asset condition and Asset Integrity Inspections will work with you to do this.
Pressure Vessel Re-certification.
There are strong economic and safety incentives to re-certify pressure vessels, pressure components, and piping for continued service after their nominal original design life has been exhausted. No specific rules, and certainly no national consensus standards exist for doing this. Therefore, methods have been developed to rank vessels as to urgency for re-certification, and a five-step re-certification process has been devised.
The five Pressure Vessel Re-certification steps are:
1) gathering design and operating information,
2) performing basic analysis to establish Maximum Allowable Working Pressure (MAWP) and to identify high-stress areas,
3) performing visual and nondestructive examination, concentrating NDT in high stress areas,
4) performing detailed stress analysis to confirm MAWP, and
5) performing flaw-growth analysis to establish the interval between inspections.
Experience has shown that re-certification costs are between 10 and 15 percent of replacement costs and that re-certification adds greatly to confidence in the safety and availability of equipment.
Another service that we provide that goes hand in hand with this one is our weld supervision and weld inspection services.
