Operational Parameters

Hot oils and heat transfer fluids can be worked either side of atmospheric pressure, although pressurised installations allowing operation above their normal saturation temperatures are more complex than for steam - partly through need to inhibit oxidation of the working medium. Even so, a mineral oil or synthetic fluid can run at 300 deg.C under normal pressure, whilst saturation pressure for dry steam at that temperature is around 85 barg. No thermodynamic pressure is induced where the fluid vapour pressure remains below atmospheric, and engineering costs are much-reduced if systems are to operate only under gravity head.

Thermal Fluids

We have built fired and unfired plant & equipment for Therminol, Shell Thermia and Dowtherm Thermal Fluid systems, and successfully work Solutia T66 at temperatures to 340 deg.C under atmospheric pressure - as for our Klieverik thermo-bonding calendering machine installation (see our Gallery page). The isometric shows a modularized pair of electric calorifiers.

Pipework Design

Although carbon steel is to be preferred for high temperature operations, we have designed, stressed, built and commissioned pressurised systems in other materials by request. Thermally-induced movement in carbon steel is lower, and properties retention much superior. Our method for pre-tensioning pipe support systems enables quick and accurate installation.
