Process: Pressure & Vacuum Vessels


Pressure and vacuum vessel fabrication is the fabrication of vessels which contains liquids or gases with a pressure that is considerably different from the surrounding pressure.

Pressure and vacuum vessels are sheet metal containers that can handle pressure differences safely. A pressure difference is always potentionally dangerous as it can cause the vessel to explode. That is why the fabrication of pressure vessels are regulated by stringent laws. Within the European Union this is controlled by EN 13445 (previously PD5500 or BS 5500 in the UK). For example; if the vessel is punctured, it is supposed to rupture along its wall to allow the pressure to adapt smoother to the surrounding pressure.

Usually a pressure or vacuum vessel have a cylindrical shape with spherical ends. This design is common because it has proven to be the safest and it also makes it relatively easy to estimate the vessel's properties.

Because of the complications associated with pressure and vacuum vessels, there are workshops which specialize in this kind of work.

    Fabrication-Pressure & Vacuum Vessels

    This is an interesting and in-depth project that encompasses a number of different manufacturing processes, including cutting, welding, turning, milling, and drilling, to name but a few. The client is a manufacturer of vacuum systems with a spend in the subcontract fabrication arena that tops £50,000. They require 1 off of the attached chamber assembly and therefore, are keen to hear from suppliers that are able to undertake the project and supply the unit complete to their specifications. In addition, the client will place repeat orders moving forward, making this a chance to grow your long-term customer portfolio.

    Fabrication-Pressure & Vacuum Vessels

    Quotes are required for Nitrogen (bladder) accumulators 3/4-16 UNF male adaptor, 55 bar 0.16 litre, welded end. The client has previously had these items manufactured overseas, but now they are keen to return production to the UK in order to improve quality and delivery. They spend over £100,000 a year on bespoke fabrications and will look to order 50 off of this unit per month from the supplier that they select.

  5. Drawings count: 10

    Fabrication-Pressure & Vacuum Vessels

    Fabrication suppliers that are able to manufacture the attached pressure vessel and lid are asked to make contact with this buyer - a company that spend over £50,000 annually on the services of subcontract fabrication suppliers. They are seeking the assistance of a Qimtek member that can adhere to the delivery deadline specified, making it ideal for companies that have immediate or imminent capacity to fill. The vessel and corresponding lid will be used within an aerospace application and there is a possibility that repeat orders could be placed at a later stage.

  6. Drawings count: 1

    Fabrication-Pressure & Vacuum Vessels

    The attached pressure vessel is destined for end use within an air conditioning unit. The client is looking to employ the assistance of a third party who can aid with the manufacture of the initial prototypes, as well as the production runs that are due to follow once testing is complete. This may make the enquiry especially well-suited to those that are looking to expand their long-term customer portfolio.

  7. Drawings count: 3

    Fabrication-Pressure & Vacuum Vessels

    The three attached pressure vessels are to be manufactured from a combination of carbon steel and mild steel, for end use within the automotive industry. The client is looking to reshore the production of these units and is keen to hear from Qimtek members who can meet the requirement within the specified time frame. As well as repeat orders of these vessels, additional work could also be made available to the chosen vendor moving forward, once a relationship has been established and quality/reliability has been proven.

  8. Drawings count: 2

    Fabrication-Pressure & Vacuum Vessels

    Operating within the industrial machinery sector, this company, who spends a massive £500,000 a year on subcontract fabrication service, seeks a new supplier who can manufacture and assemble mild steel pressure vessels. This ongoing requirement provides an excellent opportunity to add a big-spending company to your existing customer portfolio.
