Insulating A Thermodynamic Steam Trap's Inlet & Outlet

This post was written by Jack McTigue, sales manager at Thermaxx Jackets

After years of working in the insulation industry and insulating hundreds of steam components in NYC, I've observed that there is rarely insulation on the incoming (inlet) and outgoing (outlet) piping of a thermodynamic (TD) steam trap.

This is because the facility manager will need to do maintenance on the thermodynamic steam trap assembly regularly, so using hard insulation on the components would limit his or her access to them. Also, installing hard insulation on a ½”-1” pipe can be difficult. It doesn’t make sense to use hard, non-removable, insulation when you need to have access to these components many times throughout the year for maintenance.

As a result of not insulating these components, the facility is losing a significant amount of money and energy. Especially when you consider that the TD traps are normally high pressure traps (over 300°F). Our solution? Apply Thermaxx removable insulation jackets on the TD steam trap's steam inlet and outlet, as pictured below.
