Abstract：
Presents the structure characteristics, thermal performance and key points of the directly bury piping technology. Compares the economics of the directly bury and in-duct installation technologies. The result indicates that composite steam pipes directly buried can decrease the heat loss of piping remarkably and is a technique worthy of promoting. Analyses their application effect with an actual project.
Keywords:in-duct installation, composite steam pipe, directly bury, application effect
