Flanged Thermowells

We have a range of flanged thermowells suitable for high pressure and high velocity applications.

We design and manufacture a wide range of flanged solid drilled thermowells and flanged fabricated thermowells. Material options include 316 Stainless Steel, Carbon Steel, Inconel® 600, Monel® 400, Hastelloy® C276, and Hastelloy® C22.

Flanged thermowells are available with either seal welded, full penetration welded, or one piece forged style flange connections. A wide range of flange sizes and ratings are available in either raised face (RF), flat face (FF), or ring type joint (RTJ) configurations. Other options include velocity collars and cover flanges.

A variety of protective sheaths and coatings are available to protect against corrosive and high temperature processes including FEP, PTFE, tantalum, tungsten carbide and Stellite®.

To ensure stem strength and suitability we can carry out a range of tests including wake frequency calculations in accordance with ASME PTC 19.3 TW-2010, pressure testing, dye penetrant inspection, and radiographic inspection.
