Titanium Thermowell Manufacturer in Chennai
Nobel Weld is a titanium thermowell manufacturer in Chennai. We machine barstock thermowells (threaded, flanged, socket-weld and weld-in) from titanium, Hastelloy, Monel, 316Ti and duplex, and supply tantalum sheaths for the most aggressive acids.
A thermowell protects the temperature sensor from the process. In corrosive service the right alloy is the difference between years of service and a leak.
How a titanium thermowell manufacturer machines barstock wells
The well is turned from solid bar, gun-drilled for the sensor bore, and finished with the process connection: a threaded hub, a welded or one-piece flange, or a weld-in shank. Wake-frequency calculation to ASME PTC 19.3 TW can be checked against your process data.

FAQ
Thermowells: common questions
Which designs does your titanium thermowell manufacturing cover?
Threaded, flanged, socket-weld and weld-in barstock thermowells, straight, tapered or stepped, to your drawing.
Can you check thermowell wake frequency?
Yes. Send the process fluid, velocity, pressure and temperature, and we check the design against ASME PTC 19.3 TW.
What if titanium is not resistant enough for my process?
We offer Hastelloy, zirconium and tantalum-sheathed thermowells for hot reducing acids.
