Pressure Vessels and Fabrication Services: Factors to Consider in Design and Manufacture

November 3, 2017

Let's pull back from the exhaustively conducted manufacturing sequences that were carried out during the fabrication of a high-functioning pressure vessel. That's right, instead of scrutinizing the continuity of a sheet metal container or repeatedly inspecting the integrity of weld seam for the umpteenth time, the goal today is to consider the factors that guide the design and manufacturing process. It's all about the fabrication services, right?

Fabrication Services: The Underlying Principles

Function dovetails cordially with safety when the design and manufacturing factors are properly evaluated. Treated as a logistical issue, the process hangs the parts and services on a frame built from the OSHA guidelines. Directed by these codes and other process-relevant regulations, pressure vessels are built to meet the parameters of a specific operational setting. Whether that installation platform is designed to store a stated fluid or to act as a key component in a processing chain, it is imperative that the containment unit safely confines every drop and vapour wisp of this potentially hazardous fluid medium. Incidentally, even if that medium is water, there are weighty parameters to deal with here, including the high temperatures and hard to confine pressures that will transform that normally inert fluid into a dangerously energetic resource.

The Three Technology Paradigm

Take away the pressure vessel an all of the ancillary components, including the system-protecting safety valves and process monitoring instrumentation. These are the framing components that couple mathematically with the manufacturing procedures to form the outlines of the pressure vessel, but they belong almost wholly in the design half of this processing strategy. Manufacturing methodologies employ these parts and design elements as shaping and modelling tools, but it's the three-part fabrication triangle that produces the final product. In order of importance, that chain of manufacturing activity begins with machining, then it proceeds through the welding stage, before concluding at the assembly and inspection phase. Of course, several factors orbit this central processing nexus. They include the work hardening stage, the non-destructive testing phase, and the material usage proposal.

There's connective tissue tethering all of these fabrication services. They're formed by the ASME and OSHA codes. As for the important factors to consider in pressure vessel design and manufacturing, every one of those production elements binds one operation to the next. Design acuity highlights vessel geometry and material selection. Machining stations take their cues from design drawings and material types so that every conceivable tooling requirement is satisfied. Finally, the installation platform accepts the finished product, but only if that pressure vessel has been fabricated to comply with these logistically compiled design and manufacturing factors.
