Thermowells

 
 
   
EXTREME offers bar stock thermowells / sleeves are designed to meet standards established by BIS, DIN, ASME and other authorities.
Thermowells are used in industrial temperature measurement to provide isolation between a temperature sensor and the environment whose temperature is to be measured.
   
   
Thermowell Materials
Carbon Steels
Low cost materials with little corrosion resistance. Used in low temperature and stress applications where the measured medium protects it from corrosion, oils, petroleum, tars etc.
maximum temperature : 530oC
304 Stainless Steel
Low cost corrosion resistance material, used extensively used ifn food, beverage and chemical processing where good corrosion resistance is required, A low carbon grade, 304L is available which can be welded without impairing it’s corrosion resistance.
maximum temperature :900oC
316 Stainless Steel
Best corrosion resistance of the austenitic stainless steels due to the addition of molybdenum, widely used in chemical processing, offers useful resistance to H2S. As with 304, a low carbon grade, 316L is available for welded applications.
maximum temperature :900oC
Special alloy material :
Inconel, Hastelloy, Titanium, Monel, Teflon etc.
Description:
- Flange: Blindflange per ASME B16.5 / EN 1092-1 / DIN 2527
- Instrument connection: ½ NPT, G ½ female
- Bore size: Ø 6.6 mm, Ø 8.5 mm
- Insertion length U: To customer specification (max. 1800 mm for stainless steel)
- Head length H: To customer specification (standard: 57 mm, 83 mm)
Standard materials:
SS304, SS 316/ 316L, 1.4571, 1.4404, A105, exotic materials, carbon steel, brass etc.
Procedure and Certificate :-
A wide range of documentation and Non Destructive Testing can be provided on reques

TYPE : Flange mounted thermowell , Threaded mounted thermowell
Drilled Bar Stock Thermowell :
Our thermowell bodies are machine and drilled from solid bar stock. this results in a non-welded water tight unit. High accuracy machines are used to ensure concentricity of the bore with respect to the outside diameter and a consistent wall thickness over the full length of the thermowell.
