Electrical and medium Prepare voltage, power, medium and material compatibility information. Temperature and power-supply fields remain raw catalog values and do not replace project confirmation. Insertion and total length Share under-flange insertion length, total length and the vessel level or available space. If space is limited, describe service direction and clearance. Flange standard Provide the flange standard, or its outside diameter, bolt count and PCD. Name flange material and heater-sheath material separately.
Selection guide
For flange heaters, list the full interface.
The size table is a starting point; flange, sheath and vessel interfaces need separate descriptions.
