Core Viewpoint - The article highlights the essential role of heat supply personnel in ensuring the safety and efficiency of the heating pipeline network during the winter season, particularly during the Chinese New Year holiday when they remain on duty to perform routine inspections and maintenance [1][5]. Group 1: Personnel and Responsibilities - The team responsible for the heating pipeline network consists of experienced professionals, including Zhou Tong and Guo Xudong, who have been in the industry since 2007 and 2011, respectively [1]. - The heating pipeline network managed by the company spans 262 kilometers across three districts: Xicheng, Haidian, and Fengtai [1]. Group 2: Inspection Process - During inspections, personnel utilize specialized equipment such as thermal imaging cameras and acoustic listening rods to assess the condition of the pipelines [3][4]. - The temperature in the underground inspection areas can reach up to 40 degrees Celsius, creating a stark contrast with the cold surface temperatures, which can differ by as much as 50 degrees Celsius [3]. Group 3: Technology and Monitoring - The company has implemented a "situation awareness system and track inspection robots" for real-time monitoring of underground temperatures and liquid levels, enhancing the ability to detect leaks and anomalies [4]. - The inspection of each well typically takes between 40 minutes to an hour, with a total of 2,210 wells distributed across the network [4]. Group 4: Safety and Maintenance - The personnel are committed to maintaining pipeline safety, which is emphasized as a primary goal during the festive season [5]. - Each worker is responsible for 25 to 30 wells, requiring them to memorize critical information about each well, including its location, valve types, and maintenance history, to ensure quick response during emergencies [4].

Core Viewpoint - The article highlights the dedication and routine work of heat supply workers in Beijing, particularly during the Spring Festival, to ensure the warmth and safety of the city's heating network [1][3]. Group 1: Company Overview - Beijing Heat Supply Distribution Company is responsible for a heating pipeline network that spans 262 kilometers across three districts: Xicheng, Haidian, and Fengtai [3]. - The company employs a "pipeline contractor" system, where each worker is responsible for 25 to 30 inspection wells, ensuring they are familiar with the location, valve types, production years, and maintenance records of each section [11]. Group 2: Operational Details - During the Spring Festival, heat supply workers conduct daily inspections of heating pipelines in densely populated areas to ensure residents remain warm [3]. - The inspection process involves using specialized equipment such as thermal imaging cameras and electronic listening rods to detect temperature changes and potential leaks in the pipelines [9]. - The underground temperature can reach around 40 degrees Celsius, creating a significant temperature difference of up to 50 degrees Celsius compared to the surface [7]. Group 3: Technological Integration - The company has installed a "situation awareness system and track inspection robots" in the underground wells for real-time monitoring of temperature and liquid levels, which can trigger automatic alarms in case of anomalies [11]. - The combination of technology and the experience of workers allows for effective monitoring and quick response to any issues in the heating network [11].
