Product Type: Straight-form thermowell with threaded end, no flange structure
Material Specification: ASTM B564 UNS N08825 (Alloy 825), fabricated from solid bar material, precision machined to a bright surface
Stem Feature: Straight solid bar construction, maintains consistent diameter across the whole insertion segment, free of taper or stepped sections
Process Port: 3/4 inch male NPT thread, equipped with hex flat areas to facilitate assembly and disassembly using a wrench
Design Category: Threaded thermowell version, intended for pipe or vessel joints operating at relatively low pressure conditions where flange type joints are unnecessary
Surface Treatment: Bright polished metal surface covering the stem and hex fitting sections
Outstanding anti-corrosion capability: Alloy 825 material effectively resists chloride-induced stress corrosion cracking, pitting, and crevice corrosion. It maintains stable performance within oxidizing and reducing acidic media, making it fit for sour fluid and severe chemical working environments.
Easy and economical mounting: The 3/4 inch NPT threaded joint enables direct fitting onto pipe tees or threadolet components. No matched flange parts are needed, which cuts down installation expenses and space occupation.
Solid bar raw material build: Machined out of one-piece solid billet. The structure has no welded joints, delivering high mechanical robustness and dependable performance under process flow and pressure loads.
Compact straight stem layout: Constant diameter along the stem ensures steady thermal response. Compared with tapered alternatives, this style brings simpler production and replacement work.
This product applies to corrosive and sour medium process pipelines, utility piping, and low-pressure systems in the oil and gas, petrochemical, and chemical industries. It is selected in cases where a threaded connection is preferred instead of a flanged thermowell, and Alloy 825's corrosion protection property is demanded. Normally, it is used with thermocouple or RTD temperature-sensing inserts.
