Flanged Thermowells

Flanged designs providing secure, leak-tight connections for pipeline and vessel applications.

Flanged ther­mow­ells pro­vide a bolt­ed, pres­sure-rat­ed con­nec­tion for high-pres­sure pipework, ves­sels, and reac­tors where a thread­ed fit­ting is not suit­able. Avail­able with ANSI rat­ings from 150lb to 1500lb and PN16 to PN40, in RF, FF, and RTJ face types, with option­al NACE MR0175 heat treat­ment for sour ser­vice applications.

Solid Drilled Flanged Thermowell

A sol­id drilled flanged ther­mow­ell designed for use in high-pres­sure and high-tem­per­a­ture process appli­ca­tions. The flanged con­nec­tion pro­vides a secure mechan­i­cal seal, mak­ing it suit­able for demand­ing indus­tri­al environments.

Helical Solid Drilled Flanged Thermowell

A heli­cal straked sol­id drilled flanged ther­mow­ell designed to min­imise vor­tex-induced vibra­tion in high-pres­sure and high-tem­per­a­ture process appli­ca­tions. The heli­cal pro­file dis­rupts vor­tex for­ma­tion along the stem, reduc­ing dynam­ic stress­es and improv­ing reli­a­bil­i­ty in demand­ing indus­tri­al envi­ron­ments. The flanged con­nec­tion pro­vides a secure mechan­i­cal seal for robust instal­la­tion into pipework or vessels.

Solid Drilled Stepped Flanged Thermowell

A sol­id drilled stepped flanged ther­mow­ell designed to improve ther­mal response while main­tain­ing mechan­i­cal strength. Com­mon­ly used where faster tem­per­a­ture mea­sure­ment is required with­out com­pro­mis­ing process integrity.

Solid Drilled Flanged Thermowell & Coating

This sol­id drilled flanged ther­mow­ell is sup­plied with an option­al pro­tec­tive coat­ing to enhance resis­tance to cor­ro­sion and aggres­sive process media. Ide­al for harsh oper­at­ing envi­ron­ments where extend­ed ser­vice life is required.

Fabricated Flanged Thermowell

A fab­ri­cat­ed flanged ther­mow­ell offer­ing a cost-effec­tive alter­na­tive for many indus­tri­al appli­ca­tions. It pro­vides reli­able sen­sor pro­tec­tion while allow­ing flex­i­bil­i­ty in mate­ri­als, flange rat­ings, and construction.
