Pipes transporting hot media are insulated to reduce heat loss and maintain the required process conditions.
Pipes transporting hot media are insulated to reduce heat loss and maintain the required process conditions. Shoe or trunnion supports are used to support such pipes at regular intervals. Since the support is directly connected to pipe, there will be conductive heat transfer through the support and pipe. This creates an un-insulated heat bridge between the pipe and supporting structure via the support shoe or trunnion, as shown in FIG. 1.
FIG. 1. Pipe support geometry.
For high-temperature lines (≥ 400°C), a substantial amount of heat transfer can occur through the pipe support. As a result, significant temperatures can be observed on the struc
