Solid Drilled Flanged Thermowell

Product ID: FTW101

The FTW101 solid drilled flanged thermowell is manufactured from solid bar-stock to ensure strength and integrity. This heavy duty construction is designed for use within applications involving high pressures and flow rates.

The FTW101 thermowell is available with either a parallel or tapered stem profile and has wide variety of flange sizes and ratings available including RF, FF and RTJ configurations.

This style of thermowell is available with a seal or full penetration welded flange, or for ultimate strength machined as a one-piece forging. The instrument connection can be specified with a BSPP, BSPT or NPT thread which allows for easy installation of an RTD or Thermocouple temperature sensor.

The solid drilled FTW101 flanged thermowell is available in a wide selection of materials including 316 stainless steel, Alloy C276 (Hastelloy®), Alloy 400 (Monel®) and Alloy 600 (Inconel®).

In order to determine or prove the suitability and required dimensions of a thermowell based on the process conditions, we offer wake frequency calculations as per ASME PTC 19.3 TW-2016. In addition there are a number of other certification and testing services available including 3.1 material certificates, dye penetrant testing, positive material identification (PMI) and radiographic inspection (X-Ray).
