Pressure Vessels are containers which are designed to hold liquids, vapors, or gases at high pressures, usually above 15 psig. Examples of common pressure vessels used in the petroleum refining and chemical processing industries include, but are not limited to, storage tanks, boilers, and heat exchangers. Each individual vessel has its own operating limits built in by design that it has to work under, refered to as its design pressure and design temperature. Operating outside of these limits could damage the equipment and potentially lead to loss of containment or catastrophic failure.
Because they work under immense pressures, a ruptured pressure vessel can be incredibly dangerous, leading to poison gas leaks, fires, and even explosions. For this reason, pressure vessel safety is imperative. There are several standards and practices that cover the construction, maintenance, and inspection of pressure vessels. Chief among these standards are ASME Section VIII and API 510.
ASME Section VIII is the section of the ASME Boiler & Pressure Vessel Code (BPVC) that covers pressure vessels. It gives detailed requirements for the design, fabrication, testing, inspection, and certification of both fired and unfired pressure vessels.
API 510, "Pressure Vessel Inspection Code: In-Service Inspection, Rating, Repair, and Alteration" is an inspection code, written and published by the American Petroleum Institute, that covers the in-service inspection, repair, alteration, and rerating activities for pressure vessels and the pressure relieving devices protecting these vessels.
When it comes to inspections, most pressure vessels should be examined once before being placed into service and again every 5 years after every alteration or major repair. An inspection can be internal, external, or both and should involve a thorough examination, a thickness evaluation, a stress analysis, an inspection of the vessel’s pressure release valves, and a hydrostatic pressure test. It is also important to perform a surface inspection, examine the insulation and any structural connections, and finally inspect any welds or joints.

Contribute to DefinitionUndocumented pressure vessels without an ASME stamp or National Board registration are commonplace. Their potential risk and value are often poorly understood.
The objective of this survey is to determine a benchmark of fixed equipment mechanical integrity (FEMI) inspection department staffing in comparison to the amount of API 510 (or equivalent) inspections for which facility inspectors are responsible.
Pressure vessel design is crucial in ensuring compliance with safety regulations and facilitating reliability and integrity. This article provides an overview of the ASME Section VIII approach to designing pressure vessels.
Field hardness tests can provide valuable information when evaluating piping and pressure vessel anomalies. This article summarizes laboratory examinations designed to gain a better understanding of UCI hardness test results taken in the field.
The distinction between primary and secondary loads is certainly important in analysis of pressure systems. But this distinction is also important for plant operations and reliability engineers to keep in mind when dealing with day-to-day problems.
In today's chemical and refining industries, sustained long term reliability of facilities is critical to profitability and competitiveness. In fact, history shows that differences in operating expenses between best-in-class refineries, and poor...
In this edition of the FFS Forum, Greg addresses some issues associated with inspection of vessels that have been in service for a number of decades, and offers some tips for reliability and inspection to follow when inspecting these older vessels.
Hot spots – localized areas of overheating in pressure equipment – can lead to deformation or even loss of process containment. It is important to understand the effects of elevated temperature caused by hot spots on the mechanical integrity of...
An issue that arises frequently in the oil and gas industry is poor or missing documentation of pressure vessels. It is common in the industry to repurpose old equipment, bring equipment back into operation after a long period of time out of...
Are you still hitting the welded joints of pressure vessels with a hammer during hydrostatic testing? If yes, then you’re due for a refresher on the pressure testing requirements of ASME Section VIII Division 1 since this requirement was for...
The Province of Alberta has a long history of pressure equipment safety dating back to 1897 when the first boiler laws were introduced to regulate the new technology of steam boilers. Boiler inspectors were hired, and soon thereafter the Alberta...

I have written several articles for Inspectioneering Journal to help create successful programs to achieve excellence in pressure equipment integrity and reliability (PEI&R).
After a pressure equipment or piping failure, it’s not uncommon to find out during the failure analysis part of the investigation that the failure initiated at a welding flaw of some sort.
Among other things, a welding QA/QC program needs to ensure that only qualified welders, utilizing qualified procedures are allowed to weld on any pressurized equipment, including storage tanks and piping.
