Reaction Vessels
A reaction vessel holds a process medium at a controlled pressure and temperature while an agitator mixes it. Typical duties are polymerization, synthesis, fermentation and blending.
We fabricate reaction vessels from 0.5 to 200 m³ in carbon steel, low-temperature steel, stainless steel and clad plate. Agitators are paddle, anchor, turbine or propeller type, with 2.2 to 45 kW drives and variable-frequency control.
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 build a reaction vessel to our drawings and data sheet?
Yes. We fabricate to your design, or to drawings prepared by a licensed design institute. Our licence covers Class D (medium and low pressure) fixed pressure vessels, so the design pressure must be below 10 MPa.
Which agitator types and drive sizes can you supply?
Paddle, anchor, turbine and propeller agitators, with drives from 2.2 to 45 kW and variable-frequency control. Send the batch volume, medium viscosity and mixing duty so the agitator can be sized.
What do you need to confirm the vessel suits our pressure, temperature and medium?
The medium and its corrosive components, design and operating pressure, design and operating temperature, working volume, preferred material, design code, nozzle list and any heating or cooling duty.
Which inspection records come with the vessel?
A data book with the certificate of conformity, quality certificate, MTRs, WPS/PQR records, NDT reports, hydrostatic test report, heat-treatment chart if applicable, as-built drawings and packing list.
