Description

The primary protection tube (first process-side protection tube) effectively protects the thermocouple from damage caused by thermally induced movement of the refractory lining during the operation of the reactor.

Furthermore, the primary protection tube, when properly installed, effectively delays corrosion damage to the flange nozzle caused by aggressive process media.

Primary protection tube, model TW83
