For Oil & Gas applications. Vanstone type, design with collar flange

It is a specially designed thermowell for thermometer installation. The thermowell shaft and the process connection flange are not interconnected. For installation, the collar of the thermowell is fitted between two flanges; on the one hand it is fitted onto the thermowell and on the other hand it is bolted to the connection nozzle on the process side. Many different flange versions are available to secure the unit to the permanently installed nozzle flange. It is machined from solid bar stock.
