BThermowells are created to provide standard designs to meet your engineering requirements, at a lower cost, with improved service.

In general, the thermowell material chosen for the installation is governed mainly by the corrosion conditions the well will face. The high polish given to all stainless and other wells provide maximum corrosion resistance. Occasionally, the material consideration is one of strength rather than corrosion resistance. For example, a stainless steel well may be required for high pressure water service instead of a brass well which would be satisfactory from a corrosion standpoint. Consult the pressure-temperature ratings for each well type.

Wells are also available in special grades of stainless steel, Chrome-molybdenum steel, Inconel600, Hastalloy B & C, Nickel, Titanium and Monel. Tantalum jackets are also available.
