“Insulation systems appear to be simple, but doing them correctly can be complex,” says John Puskar, president of Prescient Technical Services and an expert on codes and standards related to piping, furnaces, and boilers. “Everything on a piping system should be insulated, including fittings. The most popular method is to use flexible, reusable covers custom fit for an application.
While piping is commonly insulated, facilities managers do not often cover valves, flanges, and the like. Puskar adds, “High temperature and pressure applications can cause an insulation blanket’s fasteners to fail, unless designed by a supplier that accounts for the added heat.”
