Threaded Thermowells

Screw-in thermowells for straightforward installation and reliable sensor protection.

Thread­ed ther­mow­ells screw direct­ly into pipework or ves­sels for a quick, secure instal­la­tion, with BSPP, BSPT, or NPT threads avail­able in sizes from ¼” to 1″. Avail­able in a wide range of mate­ri­als includ­ing stain­less steel, Duplex, and nick­el alloys to suit process tem­per­a­tures, pres­sures, and cor­ro­sive media.

Solid Drilled Threaded Thermowell

A sol­id drilled thread­ed ther­mow­ell designed to pro­tect tem­per­a­ture sen­sors in demand­ing process appli­ca­tions. Suit­able for high-pres­sure and high-tem­per­a­ture duties, it pro­vides excel­lent mechan­i­cal strength and long ser­vice life when installed direct­ly into pipework or vessels.

Helical Solid Drilled Threaded Thermowell

A heli­cal straked drilled thread­ed ther­mow­ell engi­neered to sup­press vor­tex shed­ding and reduce flow-induced vibra­tion in demand­ing process envi­ron­ments. The heli­cal geom­e­try dis­rupts the for­ma­tion of alter­nat­ing vor­tices, low­er­ing dynam­ic stress­es and improv­ing reli­a­bil­i­ty in high-veloc­i­ty appli­ca­tions. Suit­able for high-pres­sure and high-tem­per­a­ture duties, it offers excel­lent mechan­i­cal strength and long ser­vice life when installed direct­ly into pipework or vessels.

Fabricated Threaded Thermowell

A fab­ri­cat­ed thread­ed ther­mow­ell offer­ing a cost-effec­tive solu­tion for many indus­tri­al tem­per­a­ture mea­sure­ment appli­ca­tions. It pro­vides reli­able sen­sor pro­tec­tion while allow­ing flex­i­bil­i­ty in mate­ri­als, dimen­sions, and process connections.

Solid Drilled Threaded Thermowell with Integral Compression Fitting

A sol­id drilled thread­ed ther­mow­ell sup­plied with an inte­gral com­pres­sion fit­ting for secure sen­sor instal­la­tion. This design allows accu­rate posi­tion­ing of the sens­ing ele­ment while main­tain­ing robust mechan­i­cal pro­tec­tion in demand­ing environments.

Fabricated Threaded Thermowell with Integral Compression Fitting

This fab­ri­cat­ed thread­ed ther­mow­ell includes an inte­gral com­pres­sion fit­ting, pro­vid­ing a prac­ti­cal and eco­nom­i­cal solu­tion for sen­sor pro­tec­tion and posi­tion­ing. Suit­able for a wide range of indus­tri­al appli­ca­tions where flex­i­bil­i­ty and ease of instal­la­tion are required.
