Core Strengths

Corrosion-resistant 316 stainless steel build: Compatible with many corrosive process media. It outperforms 304 stainless steel within chloride-containing and weak acidic working environments.

High-pressure-rated flange: 1-inch 300# RF flange adapts to high-pressure process joints while maintaining compact overall dimensions.

Sufficient insertion length for precise measurement: The 200 mm insertion segment places the sensing tip deep inside flowing media. It provides faster thermal response and higher reading precision compared with shallow boss thermowells.

Standard instrument thread port: 1/2 inch NPT socket matches common thermocouple and RTD sensor modules, simplifying on-site assembly and component swapping.

Solid machined main body: Single-piece machining removes potential failure risks brought by welding seams on the pressure containment boundary.

Application Scenarios

This thermowell is applied for temperature measurement on vessels, storage tanks, and process pipelines in oil & gas, petrochemical, and general industrial facilities. It is selected when users need a 1-inch 300# flanged joint and 200 mm insertion depth to make the sensor fully contact the flowing process media.
