Important Requirements for Pressure Vessel Manufacturing

August 7, 2019

Pressure vessels contain all kinds of fluids, some of which are combustible. Other containment facilities store non-combustible gases and liquids. True, these are two different installation layouts, but they have one thing in common: both facility types contain massive amounts of kinetic energy. That means if there is a manufacturing defect present, even on a system that contains a non-combustible fluid, a catastrophic incident could occur.

All Pressure-Stored Fluid Mediums Are Potentially Dangerous

With an ignitable fuel escaping from its containment vessel while it's under pressure, a far-ranging fire or explosion takes place. Replaced by a toxic chemical, high pressures drive poisonous clouds for kilometres. Even with a non-toxic, non-flammable fluid, the stored energy could cause a highly destructive explosion, although its effects would probably dwindle away after the event occurred. That fact would be cold comfort for those who were working within the blast radius. At any rate, pressure vessel manufacturers are fully aware of this energy-storing attribute. Indeed, under the right conditions, any sealed and compressed fluid can become dangerous.

Appraising Manufacturer-Appointed Safety Requirements

Using industry standards, which include the latest, most exacting welding codes, only high-tolerance engineering techniques can be utilized when fabricating a containment casing that's built to store the substances mentioned above. Ultimately, those rolled metal sections, fittings and weld seams will be asked to function under the harshest conditions. High pressures, higher temperatures, fluid state changes and catalyzing processes, all of these containment-stressing factors will inevitably come into play. Ensuring the highest possible manufacturing standards, ASME certified welders and fabricators take charge of the project.

A Quality-Assured Manufacturing Framework

If the structural backbone of a half-finished pressure vessel has already proven itself robust, the same degree of quality-assured process coordinating competence should be present in an engineering team's fabrication workmanship. To place checks and balances on their services, an internationally ratified quality assurance program, such as the ISO 9001:2015 standards, should be implemented. Really, a manufacturing service must use a safety and quality providing service like this, for it is these programs that ultimately keep a high-energy fluid containment vessel safe and secure.

Using the above standards, pressure vessel manufacturers can add 4 separate safety nets to their fabrication services; those are two products safeguarding mechanisms bracketing two primary fabrication safeguards. Primarily, a quality-assurance thread runs through every stage, from the initial planning work to the final commissioning and installation phase. Working alongside this program, trained welders and fabricators bring their ASME certifications into the picture. Then, reinforcing those two requirements, international and local accreditations double up on an already first-rate safety factor. Last of all, providing full-on manufacturing oversight, advanced testing and inspection procedures have their part to play in every stage of the fabrication process, thus ascertaining the energy-storing capabilities of each and every expertly manufactured pressure vessel.
