How Pressure & Process Vessels works
Pressure and process vessels are specified from the design pressure, temperature, process service and operating loads. Mechanical engineering covers shell and head design, openings, supports, material selection and inspection. Nozzle orientation and access are coordinated with the project piping and maintenance requirements.
Vessel design begins with service conditions
A pressure vessel specification should establish design pressure and temperature, fluid composition, corrosion allowance, orientation, nozzle schedule, supports and governing construction code. Internal devices may include inlet distributors, demisters, baffles or coalescing elements depending on duty. Welding, examination, pressure testing and records follow the approved inspection and test plan. The vessel is then detailed for fabrication, transport, lifting and site maintenance access.

Final sizes, material grades, pressure classes, makes, testing and documentation are specified in the approved technical offer. We coordinate applicable design, fabrication, inspection and quality records against the project requirements.
Can a vessel be supplied with ASME U-stamp?
A U-stamp route can be discussed where applicable authorized fabrication and inspection arrangements are included in the approved offer.
