Weidmann, a global leader in the design, development, and operation of products and services in the energy sector, approached NCMI after they underwent an energy audit from Efficiency Vermont. Although pipe covering had been installed previously, Efficiency Vermont knew there was more efficiency to be gained through the insulation of gate valves, PRVs, steam traps, strainers, and flanges.
Maintenance personnel need access to these areas for adjustments, inspection, and routine maintenance. If traditional insulation were installed, it would be torn off and likely not replaced. NCMI’s solution to this issue was the installation of removeable insulation covers and bonnets. Removeables are made of high temperature ceramic fiber, stainless steel mesh, and Kevlar fabric that can withstand temperatures over 650 F. The covers are easy to remove and reinstall with either Velcro or wire fasteners, dependent upon necessary temperature requirements.
In some areas such as mezzanines and catwalks, removeables are installed for personnel protection where employees can get burned from exposed piping and valves. Removeables have the ability to reduce energy costs, enable periodic maintenance, extend the life of equipment and machinery and improve workplace safety.
