Request Information
Heavy-Duty, Flanged Thermowells are available in a variety of materials, flange types, flange sizes, and pressure ratings. They are also available in various lengths and with optional lagging extensions. Thermowell specifications should be determined based on process conditions which include strength, temperature, pressure and corrosion-resistance requirements. Heavy-duty flanged thermowells are supplied with a 0.260" or 0.385" bore diameter to accommodate sensing elements with a 0.252" or 0.377" maximum diameter, respectively. The tapered design is suited for heavy-duty applications where greater rigidity is required for increased pressure and flow due to process conditions. These wells are available as separate components or as part of complete sensor assemblies.

Additional Information

 N/A Maximum tapered length is 16"
("U" length for non-lagging wells) = "S" - 2"
("U" length for lagging wells) = "S" - 2" - "T"
(To solve for "T"), "T" = "S" - "U" - 2" (When "U" and "S" are specified)
