Separation Vessels & Columns
Separation vessels split a process stream into its phases: gas from liquid, solids from gas, or solids from liquid. Columns are tall vertical vessels used for separation duties in process units.
We fabricate gas-liquid separators, cyclone separators, settling and filtration vessels, and column shells in carbon, low-temperature and stainless steel. Column shells are fabricated lying on rollers in our 30,000 m² vessel workshop.
Vessels are built under our special equipment production licence TS2236612-2027 for Class D (medium and low pressure) fixed pressure vessels. We fabricate to your design, or to drawings prepared by a licensed design institute.

Can you fabricate a column to our drawings and nozzle orientation?
Yes. We fabricate to your design, or to drawings prepared by a licensed design institute, within our Class D licence (below 10 MPa). Send the general arrangement, nozzle schedule and orientation drawing.
Which separation duties do you build vessels for?
Gas-liquid separation, cyclone separation, settling and filtration, plus column shells, for design temperatures from −196 °C to 350 °C.
How are long column shells inspected?
Seams are inspected by RT in our own RT room, or by UT, MT and PT as specified. The column is then hydrostatically tested at 1.25 × design pressure with a 30-minute hold.
What should we send for a quotation?
Medium, design pressure and temperature, diameter and tangent-to-tangent length, material, code, nozzle list, internals, quantity, destination port and required delivery date.
