General Instruments Lined (Sleeved) Thermowell
GIC is the leading Lined (Sleeved) Thermowell Manufacturer providing Reliable Solutions for Accurate Temperature Measurement to the Process Industry worldwide.
One of the most economical solutions to protect the thermowells from chemically agressive fluids is to provide a bar-stock flanged thermowell made out of conventional stainless steel with loose lining in the form of a sleeve on the entire wetted portion. This will provide strength from stainless steel & corrosion resistance from the lining.

Specifications:
- Type : Bar-stock flanged
- Well Material: SS316
- Lining Material: Hastelloy® C, Nickel, Titanium, Tantalum, Silver
- Coating Material: PTFE, Alumina, Stellite, TMT (in micron)
- Lining thickness: 0.4 mm for Tantalum & Silver, 1 to 1.5 mm for other materials as standard. Other thicknesses can be provided on request.
- Process Connection: Flanged 1” (DN25) to 3” (DN80) as per ANSI or DIN as standard. Other on request.
- Insertion length: To be specified.
- Note: Sometimes even the conventional stainless steel flanged thermowells can be provided with carbon steel flange corresponding to ASTMA105, with a lining of 3 mm thick stainless steel plate on the RF portion of the flange. This construction offers a very economical solution without having to surrender corrosion resistant characteristics of stainless steels for wetted parts.
