in heating energy use by insulating bare valves and flanges.
Computers are now readily available to most producers and consumers of thermal insulation to permit use of this practice.
The computer program in Practice C 680 has been developed to calculate the heat loss per unit length, or per unit surface area, of both bare and insulated pipe. With values for bare valve or flange surface areas, heat loss can be estimated. By estimating the outer insulation surface area from an insulation manufact
