Abstract

District heating networks are critical urban lifeline infrastructure in northern China, yet their buried layout, high-temperature media, and winter peak-load operation make failures abrupt and socially disruptive. This study synthesizes publicly reported cases and a statistical review of accidents over the past two decades. Accidents are classified by subsystem (boilers, pipeline networks, heat substations, and pump stations), showing that pipeline leakage/rupture is the dominant event type. Corrosion-related degradation is identified as the leading cause (72%), followed by welding-quality defects (14%) and third-party damage (5%). An age-dependent failure mechanism is further observed: aging primary pipelines are mainly governed by corrosion and material deterioration, whereas newly commissioned pipelines are more sensitive to design and construction deficiencies. Based on accident-chain analysis—particularly water ingress, insulation degradation, and accelerated corrosion—this paper proposes a structured framework for risk identification and control to reduce casualties and service interruptions and enhance district heating resilience.
