3 Easy Steps To Calculate Heat Loss for Your Steam Pipes

Lots of commercial and industrial facilities have steam pipes used in their operational model as energy regardless if it is a school, College University or a manufacturing plant. For this reason alone it is important to measure varying degrees of thermal heat loss to save money and protect your steam pipes with removable insulation covers and blankets. Understanding how to calculate heat loss is the first step towards realizing the overall benefit removable insulation can have on your steam pipes and overall facility.

Step 1: Steam Pipe Insulation Survey

First, inspect your facility and layout your heating system notes by the hottest pipes. Locate your high-pressure steam lines, your medium-pressure steam lines, your low-pressure steam lines then you condensate return. Conduct a thorough investigation by building, room, etc. You are looking for any steam piping, valves or component that is not insulated or is insulated and has an exterior touch temperature of > 140f.

If the ladder, there is a good probability the insulation on the pipe is inadequate. Once the survey is complete, click here to download the Coverflex data base table with the following headers:

  • Location- Building or room number.
  • QTY- Length of Pipe or number of valves, traps, strainers, etc.
  • Component Type- Pipe, valve, strainers, traps, reducing, etc.
  • Flange Class- 125lb, 250lb, etc.
  • PSI or Temperature- What is the steam pressure or temperature of this component
  • Operating Hours- How many hours is this component operating per year?

Step 2: Calculating Steam Pipe Heat Loss

From the temperature and component size you will be able to calculate the BTU Loss per hour un-insulated and insulated. Your calculations will look similar to this:

Knowing the MMBTU cost for fuel will allow you to then calculate your heat loss in dollars along with an expected ROI or payback from jacket you plan to purchase.


Step 3: Removable Insulation Blankets and Covers are the Solution.

Once you’ve been able to use the above factors to calculate what your current level of heat loss is from your site, it’s time to find a solution for this issue. Removable thermal insulation jackets help to curb heat loss from your steam pipe valves, but also add another level of ease since the jackets are able to be removed at any time for any reason. These insulation blankets not only save you money because they are helping prevent thermal heat loss, but because they don’t have to replace every time your steam piping system undergoes maintenance. See this chart below to see to what extent your facility could be experiencing heat loss.
