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.
