Root sleeves
Welded root sleeves for welded thermowells
The root sleeve is first welded on the process pipe or container, and then bored to precise inner dimensions. After that the D1S/D4/D4S/D5 type thermowell is welded on the root sleeve. The root sleeve material needs to be the same as the welded thermowell. Welded root sleeves, as components:
