Pressure Vessel Engineering in Sydney. Aren’t all Pressure Vessels the Same?

Lockheed Martin Engineers at NASA’s Michoud Assembly Facility in New Orleans, Louisiana, perform the first weld on the Orion pressure vessel for Exploration Mission 1. This is the third pressure Orion pressure vessel built. Engineers continue to refine the design reducing the number of welds from 33 on the first pressure vessel to 7 on the current one, saving 700 pounds of mass.

Many clients come to us because they need pressure vessel engineering.  They often think that the only two variables to the analysis are how much the vessel will hold and how much pressure the vessel must withstand. What’s the big deal, right?

That analysis doesn’t even scratch the surface. There are many other questions to consider, the answers to which often lead to more questions. This article will explore some fundamental issues to demonstrate just how complicated the task is for pressure vessel engineers in Sydney.

Pressure Vessel Engineering Issues

The first issue is often whether the vessel is going to be holding a gas or liquid? This basic aspect can impact the components used in the design, such as pressure release valves, etc. Is there a specific temperature at which you need to maintain the material? Is the vessel used for heating or cooling, such as a boiler or cryogenic function?

You need to make a determination as to whether the material contained in the pressure vessel is corrosive or non-corrosive. That characteristic can impact upon what materials may be used to construct the pressure vessel.

Another significant design factor is how is the material going to be transported to and from the pressure vessel? Is it by a pipe or provided from a truck, etc. Are there any special nozzles or connectors required? There are also additional considerations if you need to contain material that is hazardous. You may also need to provide tolerances that need to be built into the vessel and safe zones. Also, the venting process from the pressure relief valves will be drastically different.

There are significant design issues if the Pressure vessel needs to be mobile versus a fixed vessel.

A consideration often overlooked by many clients, but that is critical to the Sydney pressure vessel engineers at Interharex is the location of the pressure vessel. A pressure vessel that is going into an already completed building may have to be assembled and tested on site. If the structure has yet to be constructed, even a large pressure vessel can be entirely built off site and delivered with heavy equipment. These are issues that impact the pressure vessel engineering.

Separate or Contain?

One unique element that most individuals don’t even consider is whether the pressure vessel is intended to keep certain material in or out? Most people only think of a pressure vessel as a container to hold something, but the vessel may actually be utilised to separate elements or compounds from each other, or in the extreme, be a vessel to contain people in an extreme or hazardous environment.

These are just some of the general considerations in pressure vessel engineering that we at Interharex deal with on multiple projects with great regularity. The complexity of issues faced when pressure vessel engineering in Sydney, is why you should only trust your pressure vessel project to us. We have the experience, tools and know-how to get the job done right and meet or exceed all your needs and expectations.
