Maintenance Service will be on a rotating basis, each visit covering an area or system of the facility, so that at the end of each year, all accessible insulation systems have received the scheduled maintenance or inspection. A Maintenance Technician will make minor repairs as needed including the following:
Repair or replace caulk – keeping the insulation dry is very important in any insulation system.
Repair or replace mastic – for vapor retarder or aesthetics, keep fibers of insulation from becoming air-born.
Repair or replace bands that have become loose or are missing – keeping the protective jacket intact keeps insulation from becoming wet or damaged.
Repair or replace tape – vapor barrier, aesthetics, keeping fibers from becoming air-born.
Repair or replace glue – whether it be a vapor barrier or a protective cover for insulation, it is an important part of the insulation system as a whole.
Reinstall blankets – sometimes blankets are removed for maintenance and not reinstalled properly or at all. This can be an issue of Personnel Protection and or energy savings/ heat loss.
Reposition aluminum/stainless steel jacketing that is not damaged – sometimes the jacketing moves due to changes in weather, bands being loose, or vibration of the piping. Again, this jacketing is installed to protect the insulation that it covers as well as aesthetics.
If the insulation were found by the technician to still be dry during one of the routine visits, he would install new Zero-Perm tape to restore the vapor barrier, reposition the aluminum jacketing, and install new caulk to keep moisture out.
If the insulation were found by the technician or inspector to contain moisture, the technician could apply a temporary vapor barrier to prevent more moisture from entering the system, and report the issue. Recommended action would be to visually inspect for CUI (Corrosion Under Insulation) and assess how much of the insulation system had been damaged by moisture and replace it. If caught early (approx. 21 linear feet) and assuming no loss of integrity to piping, the cost would be as follows:
If this were to be left as is, or not caught early, moisture would continue to infiltrate the insulation system. Recommended action would be to assess how far the moisture traveled as well as visually inspect for CUI. If we assume moisture traveled 100 linear feet and there was no loss of integrity to the pipe, the cost would be as follows:
