Abstract Design on line 11LCH-BR001-100-BB2-H, connected from the High Pressure Heater to the deaerator, has a diameter of 4 inches and a length of 53.3 meters. The specified temperature for the operating conditions is 186.6°C, and the pressure at the operating conditions is 23.45 bar. Due to the high temperature nature of the pipeline, insulation needs to be added, and an analysis is required to determine the optimal insulation thickness and material selection.The addition of insulation is necessary to prevent excessive heat loss and maintain the safety and performance of the piping system. Based on the analysis of nine insulation variations, it is determined that the type of material and insulation thickness have an impact on the heat loss value and downstream temperature of the pipe. For the optimal insulation selection, mineral wool material with a thickness of 50 mm is chosen. From a technical perspective, the heat loss value and downstream temperature for this material are 7077.056 watts and 186.095 degrees Celsius, respectively, which are considered low. In terms of economic cost, this material is affordable, with a total cost of Rp19,094,370.65. Therefore, mineral wool insulation with a thickness of 50 mm is deemed optimal both economically and technically.
