The HTS Thermolet is a simplified device developed by HTS engineers specifically for the installation of thermowells, annubars, and similar instruments onto a pipe or vessel while at operating temperature and pressure.

The use of the Thermolet simplifies and speeds up welding and hot tapping operations, thus saving time and money.

Because of the Thermolet's design, no special alignment procedures are required when it's welded onto the line or vessel.

Once in place, a valve is screwed onto the Thermolet and a hole is tapped by HTS into the vessel or line.

Specialized HTS equipment is used in the tapping and Thermowell setting operation.

The same techniques can be used to install coupon holders, hydrogen probes, electronic probes, flow meters, and product injectors.
