Technical SupportTop 3 Reasons Industrial Process Systems Utilize Thermowells Measuring temperature is a crucial part of any industrialprocess system operation. Whether it is mechanical (i.e.,bimetal or gas actuated thermometers) or electrical (i.e.,thermocouples or RTDs - resistance temperature detectors);all thermometers are highly susceptible to damaging mediaconditions like f low , corrosion, abrasion, temperature,pressure and turbulence. Limitations in thermometer designs make it challenging tospecify against these types of harsh environments. Aproduct failure can halt production to even the largest ofmanufacturing plants. Damaged thermometers cancontribute to leaking media, safety issues, or a productionstandstill. Thermow ells are the perfect solution for preventing production shutdow ns and are often found in the f inestindustrial process systems w ithin refineries, petrochemical and chemical plants. A thermow ell is essentially aprotective barrier betw een a thermometer and the process media. It also allow s for easy access to service athermometer and can reduce operational costs in a process plant environment. Protective Barrier

A thermometer f its inside a thermow ell like a hand in a glove. Similar to a glove, its foremost feature is toprovide protection against external conditions. Thermow ell materials are treated and tested to handle a w idevariety of corrosive or abrasive process media and machined to handle turbulent or high pressure conditions.This “protective barrier” also shields the thermometer’s sensing element from extreme hot or coldtemperatures.

Better Serviceability

Thermow ells provide easy access to remove or replace thermometers. They stay installed in the pipingsystem w hile a thermometer is being serviced. This allow s for the operation to not be disrupted, thuspreventing unnecessary dow ntime and allow ing the process media to continue f low ing w ithout w orry ofescaping the system. Reduced Operational Costs

Because thermow ells provide a “protective barrier”, thermometers last longer and service requirementsbecome less frequent. This helps decrease the total cost of ow nership by minimizing the maintenance andoperators service time, as w ell as, reducing replacement costs and inventory levels of thermometers. Why WIKA

There are several specif ications to consider w hen selecting a thermow ell. For example: connection size andtype, style, bore diameter, stem length, insertion length, w all thickness, type of w eld or mount, and the mediacomposition and condition. WIKA Instrument Corporation can assist w ith all these variables and more.

Thermowell Sizing

Thermowells

WIKA offers a vast range of thermow ell materials, and can provide a PositiveMaterial Identif ication (PMI) or Mill Test Reports (MTR) upon request. Additional Non-destructive Testing (NDT) is available including: Liquid Penetrant Inspection (LPI),ultrasonic (UT), hardness testing, radiography (RT), and pressure testing. WIKA can provide thermow ells to meet ASME PTC 19.3-2010 standards andcompliance w ith ASME 31.3 piping system requirements. Options are also availablefor approved w elding procedures and NACE certif ication. To assist w ith design specif ications, a thermow ell sizing program is availableonline. WIKA Instrument Corporation is the engineering solution for protecting anindustrial processing plant’s thermometers from harsh environments.
