THERMOWELLSThermowell Design and Selection CriteriaA thermowell is a pressure-tight receptacle that protects and extends the life of a temperature sensor in processingapplications where the sensor is not mechanically or chemically compatible with the process environment. Installeddirectly into the piping systems, thermowells facilitate sensor replacement in high-pressure pipelines and eliminatethe need to interrupt the process flow or drain the process system for sensor maintenance functions. The use ofstandardized thermowells permits simple relocation of sensors throughout a plant.Strength versus accurate and fast temperature measurement is a balancing act. The factors which tend to producehigh strength also tend to reduce the temperature sensor's accuracy and speed of response. A properly selectedthermowell will balance these opposing factors to produce a design capable of functioning satisfactorily in theintended application. The listed factors are a general guide and are not all inclusive. Refer to ASME PTC 19.3 TWfor a more authoritative dissertation on proper thermowell selection.TAPERED STEM:-BALANCE BETWEEN STRENGTH AND ACCURACY-HEAVY DUTY APPLICATIONS-HIGH RIGIDITYTHINWALL THICKNESSTHICK(BEST MEASUREMENT)(BEST STRENGTH)-HIGH RIGIDITY & NATURAL FREQUENCY-REDUCES STEM-INCREASED RESISTANCE TO BENDINGCONDUCTION LOSSSELECTION MUST PROVIDE:-PROCESS TEMPERATURERESISTANCE-PROCESS FLUID CORROSIONAND EROSION RESISTANCE-MECHANICAL STRENGTHSTRAIGHT STEM:-STANDARD CONSTRUCTION-GOOD RIGIDITY-HIGH STATIC PRESSURE-REDUCES RESPONSE TIMEMATERIALSTEPPED STEM:-FASTER RESPONSE-REDUCED STEM LOSS-GOOD RIGIDIGYTHREADEDSTEM GEOMETRY& VIBRATIONAL STRESS-INCREASED CORROSION & EROSION LIFEHEX ORWRENCHFLATSIMMERSION LENGTHLONGERSHORTER(BEST MEASUREMENT)(BEST STRENGTH)-PLACES ACTIVE PORTION OF-INCREASES RIGIDITY & NATURALSENSOR DEEPER INTOFREQUENCYPROCESS STREAMPROCESS CONNECTIONLAG EXTENSION-MUST MATCH MATING CONNECTION-MAINTAIN PRESSURE-TIGHT RIGID CONNECTION-MEET ANY APPLICABLE CODES(OPTIONAL)- MOVES SENSORCONNECTION PASTINSULATING WALLIF REQUIRED- INCREASES RESISTANCES TO-REDUCES STEM CONDUCTIONBENDING & VIBRATIONAL STRESSWELDEDFLANGEDPROCESS FLUID VELOCITYFASTER (BEST MEASUREMENT)SLOWER (BEST STRENGTH)-INCREASES HEAT TRANSFER-REDUCES BENDING STRESS-REDUCES RESPONSE TIME-REDUCES VIBRATIONAL FORCING FREQUENCYFOR:TITLE:SPEC NO:CATALOSIZE:TOLERANCES 1/32"DECIMAL DIM .XX 0.010"DECIMALDIM .XXX 0.005"Phone (260) 484-2580 FAX (260) 482-6805 or (800) 837-6805 www.pyromation.com 2 ANGULAR DIMFRACTION DIM91-9 This document is PROPRIETARY toADRAWN BY:J.

THERMOWELLSReduced-Tip, Socket-Weld ThermowellsReduced-Tip, Socket-Weld Thermowells are available in a variety of materials, process connection sizes, lengths, and optionallagging extensions. Thermowell specifications should be determined based on process conditions which include strength,temperature, pressure and corrosion-resistance requirements. The Reduced-Tip Socket-Weld is designed to be used with a class3000 weld-o-let which allows the thermowell to be welded permanently into the process. The stepped construction is used instandard-duty applications and increases the speed of response while maintaining mechanical strength.They are designed withstandard 0.260" bore diameters to accommodate sensing elements with a 0.252" maximum diameter.
