Description

The TW32 series of thermowells with hub connection are designed for use with a wide range of electrical and mechanical WIKA thermometers. Their robust design makes them the preferred solution for applications in the petrochemical industry as well as in the oil and gas industry especially where only limited mounting space is available.

Thermowells assume a central function within temperature measuring locations: They separate the process space from the environment, thus protecting both the operating personnel and the environment and protecting the temperature probe from aggressive media, high pressures and strong flows. At the same time, they enable the replacement of the thermometer during operation.

Special features

  • Suitable for hub connections of numerous manufacturers
  • Solid-machined version without weld seam
  • Much smaller size than comparable conventional flanges
  • High leakage safety through metal sealing
  • Best fatigue strength for wake frequency calculations in accordance with ASME PTC 19.3 TW-2016

Wake frequency calculationCalculation of individual thermowells in accordance with ASME PTC 19.3 TW-2016 minimises the risk of dynamic damage that can be caused by the vortex shedding of a Kármán vortex street (Vortex Induced Vibration; VIV). In addition, the static loads due to lateral flow and the process pressure are calculated depending on the temperature. The calculation can be carried out independently using an online tool or as a WIKA engineered service (subject to charges).
→ For further information, see technical information IN 00.15 'Wake frequency calcula- tion'.
Insertion length U WFCThe groove depth G must be added to the insertion length U. U WFC = U + G Example WIKA hub size 2W20 with U = 300 mm: U WFC = 300 mm (11.811") + 17.5 (0.688") = 317.5 mm (12.5")
