TT511 bar stock thermowell, Vanstone-type metric thermowell designed for the oil and gas industry
Advantages
-
Solid thermowell made from drilled bar stock.
-
The standard product meets the specific requirements of various industries. The insertion depth and the thermowell structure can be flexibly selected according to the process parameters.
-
Complies with Shell specifications: S.38.113 (revision D) and S.38.114 (revision D)
-
Precise thermowell calculation ensures safe plant production.
-
The Vanstone design significantly reduces costs:
After replacing the thermowell, the flange can be reused, allowing flexible selection of the flange material and reducing spare parts and warehousing requirements.
Field of application
Thermowell specially designed for thermometer installation. The thermowell stem and the process connection flange are not connected. During installation, the thermowell flange is placed between two flanges; on the one hand it fixes the thermowell, and on the other hand it bolts the connection nozzle to the process side. Various types of flanges are available to permanently fix the device to the installed nozzle flange. Machined from solid bar stock.
The thermowell can be used in industries with high process requirements. It is mainly used in the oil and gas and petrochemical industries. The process connection flange is not welded to the base of the thermowell but is designed as a Vanstone flange. The special Vanstone thermowell design enables a wide range of applications and is suitable for RTD and thermocouple thermometers.
