Standing in harsh industrial settings, pressure vessels are built to work efficiently and to last for ages. Therefore, if there's really a process-hampering factor or material-debilitating influence lurking, one that's silently undermining a pressure vessel's key design features, it needs to be identified and removed fast.

Potentially seen as a pressure vessel weak point, nozzle problems have been known to take precedence over other design features. As a matter of course, vessel geometries, wall thicknesses and weld seams account for the majority of this expert team's focus. All the same, from a safety standpoint, welded vessel nozzles are treated with equal respect, for they have been known to develop significant flaws.

Without preamble, let's talk about non-destructive pressure vessel testing. Long story short, vessel welds are not exposed to damaging sampling energies when they're inspected by NDT (Non-Destructive Testing) equipment.

Even when a fabrication service has access to the finest manufacturing facilities, it's not possible to manufacture a high-performance pressure vessel if it's not equipped with an alloy-strengthened material backbone. Stretching that metaphor just a little further, the materials require flexibility, again, just like a backbone.

When handling flammable liquids in Australia, you turn to the AS1940:2017 guidelines. It's in this document that the different classifications of combustible liquids are detailed. They deal with denser state fluids, plus the vapours that are discharged by those condensates. From handling the potentially incendiary fluids, the regulations turn a cautious virtual eye towards their storage. From handling guidelines to pressure vessel storage cautionary measures, the procedures amass.

As the post heading implies, there are different types of pressure vessel materials, and they are used in different applications. Destined for a variety of fundamentally contrasting usage domains, it's easy enough to alter the geometry of a pressure vessel or to thicken its walls

The descriptive term provides an important clue, so we're ready to take a guess at the role this test technique plays. Being engineers, however, there's no room for guessing, so let's get the explanations down in black-and-white right now.

Pressure vessels seem static, at least from a distance. They stand tall and resolute, but they also remain idle. That's not exactly true, though. Pressure vessels swell as they endure hoop stress.

Just as the term implies, fractures are cracks. In pressure vessels, the cracks propagate because of brittleness. How maddening is this situation? It's a disturbing material defect, to say the least.

Heat exchangers are exposed to stress. Every day, all day long, the heat trading devices are hit from two different directions by two different fluid mediums.

Available in two forms, furnace vessels are manufactured as either direct fired or indirect fired heaters. Now, everyone can recognize a direct fired unit when it's seen in use. It's the model that comes attached to a burner assembly.

Familiar conventions endure in heat exchanger design. There are the shell and tube layouts, which are commonly placed alongside plate type heat exchangers.

Like a thermos, perhaps full of piping hot tea, jacketed tanks use an additional layer of encircling material to regulate fluid temperatures. Unlike a thermos, the second layer isn't made of fragile glass.
