Thermowell
STW
Industrial Process Thermowells
Thermowells drilled from solid bar stock of heat- and corrosion-resistant alloys. Designed with automatic Kármán vortex and resonance calculations; up to 2 m in one piece.
Features
- Two-shaft gun drilling machine up to 2 m depth + latest NC turning machines
- Mechanical strength calculated against Kármán vortex shedding and resonance
- Flanged (STW DF) · Socket weld (STW DW) · Hex thread (STW DH) · Pipe hex thread (STW PH)
- Options: helium leak test, dye penetrant (PT) test, mill certificate cross-check
Applications
Sensor protection in high-temperature, high-pressure environments in power plants, steelworks, chemical plants and refineries. Applicable to LNG and hydrogen tanks, pressure vessels, heat exchangers and piping systems.
