Ms Mi Thermocouple or Resistance Thermometer sensor fitted into a terminal head, and provided with head extension and drilled bar stock weld-in thermowell would form a typical complete assembly ready for use in the application, designed for. The design of the complete assembly depends on various process parameters, such as, temperature, dynamic pressure, flow velocity, abrasive nature of process fluid, intricate nature of installation and insertion lengths required.
Various designs are avilable as standard products , one of which is illustrated in this leaflet. We can design and manufacture assemblies, single/duplex as well as multipoint to suit practically every process. Thermowells are available in standard AISI 300 series stainless steels as well as, in ferritic steels such as 13CrMo44 or 10CrMo910.
The standard execution is with plated CS extension and Aluminum head with screwed cover and conduit entry of PG16 and undergrounded junction for Thermocouples. |

The Thermocouple or RTD assembly illustrated in this leaflet is with a weld in Thermowell having straight shank with a tapered tail. These wells are provided with a cylindrical head suitable for welding into a socket weld or a straight through socket.
High Velocity collar can be provided to reduce the suspended length of Thermowell and to meet ASME PTC19.3 requirement.
Thermowells are available in standard AISI 300 series stainless steels as well as, in exotic materials such as Incoloy 800, Inconel 600, Monel 400, Hastelloy alloys C and B.
The standard execution is with plated CS extension and Aluminum head with conduit entry of 1/2" NPT and Thermocouples with ungrounded junction unless specified otherwise. Define dimension B1 same as Dimension 'B',when a fully straight shank well is required. |

The assembly is with a weld-in Thermowell manufactured from bar stock as per ASTM A276 grade 321SS or 316SS, duly tested prior to manufacture as per agreed QA plan. These assemblies are used for temperature measurement of high pressure and high velocity steam lines and are largely used in performance testing of utility boilers.
The Thermowell is butt welded on the weldolet provided on the pipings and the collor provided on Thermowell fits snugly in the pipe wall, thus reducing the suspended length of the Thermowell, and thereby meeting the ASME PTC19.3 code requirement.
Thermowells are provided with IBR certification, material integrity test certificates, and are also subjected to a heat treatment at 950 deg C prior to final finishing. A plug and chain is provided, when Thermowells are supplied as "Test wells".
The standard execution is with plated CS extension and Aluminum head with conduit entry of 1/2" NPT and ungrounded junction for thermocouples unless otherwise specified. |
