PRESSURE VESSEL DESIGN & ENGINEERING
In house capability
FlexEJ uses PV Elite suite for calculations which integrates with our Solid Works for design and detailing. Material traceability and NDT are both managed through a specially developed database which integrates with our business system for instant reporting and indexing/retrieval of certification ready for inclusion in the manufacturing data book.
We have long experience of working with OEMs to design and build the pressure boundary for specialist internals such as filters, strainers, de-misters, separators, heaters and silencers.
Alternatively, FlexEJ offers build-to-print where the code calculation has been completed by others and the design envelope exists or we can take concept drawings forward to full manufacturing designs.
Filters, Strainers, Silencers, Flares.

A. No, we only manufacture to order. For sales assistance please contact us or use our Live Chat facility.
A. To design a pressure vessel we need to know the design pressure, temperature, working fluid, volume (or length & diameter) and what material is required. The number and size of connections to the vessel has a big impact on both the design and cost so this is also useful early design information.
