Thermowells are designed to prevent direct exposure of the media to thermocouples and to resistance thermometers when mounted in pressurized vessels, pipelines, steam boilers or other objects.
THERMOWELLS ARE AVAILABLE IN SIX MODELS:
- GCR - Straight and stepped screw-in thermowells (see details->)
- GKR - Tapered screw-in thermowells (see details->)
- GCP - Straight and stepped weld-in thermowells (see details->)
- GKP - Tapered weld-in thermowells (see details->)
- GCF - Straight and stepped thermowells with flange (see details->)
- GKF - Tapered thermowells with flange (see details->)
Thermowells are manufactured with the following threads:
metric thread according to GOST 24705,
parallel pipe thread according to GOST 6357
tapered pipe thread according to GOST 6111.
Process connection thread can be made at the request of the customer according to other foreign standards.
Flanges of thermowells are made according to GOST 12821, with flange face and mounting dimensions according to GOST 12815 for the specified rated pressure.
Flanges can be made at the request of the customer according to other foreign standards.
Thermowells should be operated at flow rates and pressures not exceeding the values shown in the tables for corresponding thermowell modifications. The maximum flow rate and the rated pressure of medium are determined based on the static strength of the thermowells. The calculation is made for a medium with a density 1000 kg/m³ at a temperature 20-200ºС.
Thermowells of all modifications are hermetic. They are subjected to tests by the test pressure Рpr and should be operated at the working pressure Рr in accordance with GOST 356.
