Reasons To Use Thermowell In Industrial Process Operation System

by Mercert

The thermocouple is a temperature determining instrument exposed during a temperature measurement process. Thermowell guards the thermocouple, bimetal thermometers, & thermistors temperature sensors & thermocouples from damages caused by corrosion, material velocity, & excessive pressure.

Other functions of thermowell include

  • Maintain the reliability of the system’s pressure boundaries
  • Enhance the durability of the sensor
  • Allow the safe replacement of sensors by decreasing the contamination possibility & system drainage.

Serious problems can occur in manufacturing plants without thermowell, like leakage, safety issues, and damage.

Thermowells are usually present in petrochemical, chemical, & refineries industries. Let’s discuss how thermowell can serve the plant in the protection process.

Protective Barrier

The major role of thermowell is to protect the system from the external condition, which includes pressure, corrosion, temperature, damage, and many more. The safety of a thermometer is very important & any simple problem can cause huge damages from both yield and safety perspectives—thermowell guards all the sensing elements of a thermometer from being exposed to extreme conditions.

Minimize Operational Costs

Thermowell increases thermometers’ life and work, and you do not need to pay for maintenance too often. Thermowell will save not only much cost but also the time and effort you spend on services. Save your money at the end and stop investing in thermometers too much.

Improved Serviceability

Thermowell makes it easy for you to replace and remove the thermometer. You do not need to remove the thermowell, and they keep in position even when the thermometer is being serviced. That means there is no unnecessary interruption in the system, and operations continue.

Factors That You Need To Consider While Purchasing Thermowell

Even though thermowells can save your system from damages increase their longevity, the purchase of thermowell is much more complex than your imagination. You need to consider many factors while choosing thermowells. These factors include:

  • Type
  • Style
  • Bore diameter
  • Stem length
  • Connection type
  • Wall thickness
  • Insertion length
  • Type of mount or weld
  • Media condition and composition
  • Mill Test Reports (MTR) or Positive Material Identification (PMI)
  • Non-destructive Testing (NDT), comprising: ultrasonic (UT), Liquid Penetrant Inspection (LPI), radiography (RT), hardness testing, and pressure testing

Types of Thermowells

The categorization of thermowell is based on the design of the stem. The most common types are

  • Threaded thermowells
  • Socket weld thermowells
  • Weld-in thermowells
  • Flanged thermowells
  • O-Ring thermowells

Thermowells are made from a variety of different materials based on their applications. The most common materials from where you need to select one are carbon, steel, brass, stainless, Monel, Incoloy, titanium, nickel, and Hastelloy.

Conclusion

Being an important part of the system, thermowell purchase is a very challenging task. This task becomes more challenging when the market is full of various options. But here we are providing you with one of the best manufacturing companies and the things that you should keep in mind. Make sure to read it all to avoid any hassle.
