These vessels usually have been designed and made for transit fluids with high pressure. These vessels are used in different dimensions .These vessels are like Shell& tube with this difference that they don't have Tube Bundle and only have shell; the moving fluid in them is only one type and has usage in refineries and petrochemistry industry. Sometimes they use sump or filters in pressure vessels to refine fluids.

These vessels are high pressure tolerant. We have used Asme SecVШ standard and Pv Elite software to design these vessels.
