Features & Benefits

Easy Installation and Reduced Cost

The threaded connection requires no hot work for installation or removal, lowering site construction difficulty and maintenance costs. It is suitable for quick deployment on medium and low pressure, low flow velocity pipelines.

Online Maintenance Capability

Sensors can be replaced while equipment stays online without shutdown or pipeline draining, avoiding interruption to continuous production for routine calibration and maintenance of process units.

Broad Standard Compatibility

Thread sizes comply with widely used industrial standards including M27, M33, M60, 3/4” NPT, 1” NPT and 2” NPT. Simple selection rules make it applicable to most medium/low-pressure, low-flow services in steel, thermal power, fine chemical, food and general assembly plants.

Reliable Structural Strength

Integrally machined thermowell maintains structural integrity. Strength and vortex resonance frequency are verified per ASME PTC 19.3 TW at order stage, offering good vibration and erosion resistance for medium and low pressure working conditions.

Applications

Steel Industry, Thermal Power Generation Industry

Steel Industry, Thermal Power Generation Industry

Generally used for measurement points on medium- and low-pressure, low-velocity process lines and auxiliary systems in steel plants, thermal power plants, and other industries, where the media are non-hazardous water and steam. The threaded connection facilitates scheduled calibration, installation and removal of sensors, meeting routine temperature measurement requirements of the steel and power generation industries.

Fine Chemical, Food Processing & Assembly Facilities

Fine Chemical, Food Processing & Assembly Facilities

Mainly used in low-velocity applications across fine chemical processing, food processing, and mechanical equipment assembly, where media are of low hazard. The threaded design offers convenient installation and low maintenance costs, providing practical temperature measurement protection solution for common pressure piping and equipment, and is suited to conditions requiring frequent sensor maintenance.
