Ms Mi Thermocouple or Resistance Thermometer sensor fitted into a terminal head, and provided with head extension and drilled bar stock 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 available as standard products. 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 steel 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 ungrounded junction for thermocouples. |

Ms Mi Thermocouple or Resistance Thermometer sensor fitted into a terminal head, and provided with head extension and drilled bar stock thermowell as per ENI standard 0165.00,is ideally suited for use in Fertiliser plants, Refineries and Petrochemical complexes.
The assembly can be supplied with 316SS terminal head and nipple- union-nipple in 316SS as a standard feature in weatherproof or flameproof execution. This will resist atmospheric corrosion and help in carrying out periodic maintenance with more ease.
Heavy duty well with process connection of 1.5"NPT and tapered shank tapering from 38mm to 33mm is offered as a standard design for use on very high pressure application such as syngas compressor discharge.
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 316SS extension and Aluminium head with conduit entry of 1/2"NPT(F) and ungrounded junctions for Thermocouples. |

Various designs are available as standard products, few of which are illustrated in this leaflet. We can design and manufacture assemblies, single/duplex as well as multipoint to suit practically every process application.
Thermowells are available in standard AISI 300 series stainless steel as well as, in exotic materials such as Incoloy 800, Inconel 600, Monel 400, Hastelloy alloys C & B
The standard execution as shown in this leaflet is with plated CS extension and Aluminium head with conduit entry of 1/2"NPT and stepped shank Thermowell . Specify option 9 for Thermowell with straight and tail portion of 65mm as tapered portion. The Thermocouple junctions are ungrounded unless specified otherwise.
The assembly shown above is that of a mercury in steel temperature gauge with thermowell. Bi-metallic or Gas filled gauges can also be supplied if specified. |

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.
ASME performance test code PTC 19.3 gives a basis for arriving at a design of thermowell for use on pipings carrying process fluids. We recommend that insertion lengths are checked for safe design as per ASME PTC 19.3
The assembly is typical for use in Power Plants for use on steam and water services.
Thermowells are available in standard AISI 300 series stainless steel such as 316 SS, 304 SS, 321 SS.
The standard execution as shown in this leaflet is with plated CS extension and Aluminum head with conduit entry of 1/2" NPT(F) and well entry M 20 x 1.5. Assemblies with longer extension length to locate cold end termination away from the installation can be supplied. Specify code 10 and requirement of extension length. The thermocouple junctions are ungrounded unless specified otherwise. |

Ms Mi Thermocouple or Resistance Thermometer sensor fitted into a terminal head, and provided with head extension and solid sintered Tungsten carbide Thermowell would form typically, a complete assembly for use in the Power Plants for highly abrasive services such as mill classifier outlet for temperature measurement of Coal + Air mixture
For use at relatively high temperatures we recommend re-crystallized Silicon carbide , which also has very high abrasion resistance characteristics. These are recommended for use in Flue gas application in power plants or for use on incineretors employed in modern day waste management systems of process plants. Standard well is available in diameter of 20mm; and is cemented into stainless steel bushing.
The standard execution as shown in this leaflet is with plated CS extension and Aluminium head with conduit entry of 1/2"NPT(M), and well entry of M20*1.5 |
