Weld-In

TWT-W

Tapered Weld-In Thermowell

Weld-in thermowell for installations where threaded process connections are prohibited by code, specification, or regulation. The direct weld-in connection to the pipe wall or vessel nozzle provides the highest possible pressure boundary integrity. Used in nuclear power, high-purity semiconductor processes, and regulatory-mandated applications. Tapered shank provides optimal vibration performance. Full weld documentation available.
