Flanged barstock thermowells

Instrumentation · Temperature

Nuova Fima W93 flanged thermowells protect thermometers, probes and thermocouples from corrosion, high pressure and process fluid velocity, and allow the instrument to be removed, recalibrated or replaced without shutting down the plant. They are machined from solid barstock with a tapered shank and flanged connection, making them suitable for the most demanding service. The low roughness of the wetted parts (Ra ≤ 0.8 µm) increases fatigue resistance, and the double weld between shank and flange improves bending and pressure resistance and prevents leakage under shocks or overpressure. Their strength is verified according to ASME PTC 19.3 TW-2016. Shank and flange are AISI 316L (Monel 400, Hastelloy C276, Alloy 625, Duplex or Super Duplex on request), with ASME B16.5 flanges from 1" to 3" in classes 150 to 2500 and RF or RJ facing. They withstand nominal pressures up to 420 bar at 20 °C and process temperatures from -200 to +600 °C depending on material, with total length up to 770 mm and bore diameters of 7 to 12 mm. Options include NACE MR0103/MR0175 (ISO 15156-3) certification, internal and external hydrostatic tests, dye penetrant test and plug with chain. At Tecnovent we help you size the thermowell for your process conditions.
