The Yinchuan Kunming Expressway (G85) starts from Yinchuan City, Ningxia and ends in Kunming City, Yunnan. It has a total length of 2322 kilometers and is one of the north-south longitudinal lines in the National Expressway Network Plan. The north-south route runs through the core hinterland of China, and has a significant radiating and driving effect on the economic and social development of the western inland region. The Yinchuan Kunming Expressway (G85) Ningxia Taiyangshan Pengyang section project, with a total length of 236 kilometers, is the largest single investment project in transportation in Ningxia. Anhui Huanrui has undertaken the design, supply, and commissioning of the fire pipeline electric heating project for the Dazhaiyuan Tunnel Group, Shibaozi Tunnel Group, Xiling Tunnel, Ankou Tunnel, Shenyu Tunnel, and Shengli Tunnel in this project. The climate conditions of the project location have an extreme minimum temperature of -30.2 ℃. The tunnel fire pipeline system is distributed throughout the entire tunnel system, and the entire pipeline is flushed with water. In winter, pipelines are prone to freezing, leading to pipeline explosions and affecting driving safety. In case of fire, firefighting operations cannot be carried out. Anhui Huanrui Tunnel Fire Pipeline Electric Tracing System According to the characteristics of the environmental temperature of the tunnel, the temperature inside the extra long tunnel is higher than that outside the tunnel, and as the distance from the tunnel entrance increases, the influence of the temperature inside the tunnel gradually weakens. In this project, our company recommends using a segmented laying method. The model RDC3-J3 three core series constant power tracing cable is laid in the pipeline outside the tunnel and within 1000m of the tunnel entrance, with lengths ranging from 800-1250m. This model of heat tracing belt is suitable for insulation and heat tracing of long-distance pipelines. A single power point has a long radiation distance, and the heating power of the heat tracing belt is constant and uniform, with a service life of over 20 years. It is the preferred heat tracing method for long-distance tunnel fire protection pipelines. In this project, electric heat tracing control cabinets are installed in the substation inside and outside the tunnel, and the power is taken from the low-voltage distribution cabinet of the substation. Introduce constant power heat tracing cables from the electric heat tracing control cabinet to the fire protection pipeline network inside and outside the tunnel. Temperature sensors are installed on each circuit pipeline, and the electric heat tracing control cabinet uploads temperature signals and control signals to the tunnel monitoring room for unified management through the industrial Ethernet switch of the tunnel monitoring system. This electric heat tracing remote control system can provide real-time temperature and high/low temperature alarms on site, an...
View MoreIn the new energy industry, gas pressure regulating devices are very important equipment. Huanrui Electric Heat Tracing Products can be directly applied in various pipeline protection, and can also provide heat tracing solutions for equipment production in new energy enterprises, thereby directly or indirectly providing high-quality services for the new energy industry. Recently, Huanrui Company has completed the heat tracing requirements for industrial equipment for a high-tech enterprise in the field of clean and comprehensive utilization of new energy, mainly engaged in technology research and development, engineering design, equipment manufacturing and integration, engineering construction and management of petrochemical and coal chemical industries, and provided heat tracing services for gas pressure regulating equipment exported to Iran. The gas pressure regulating equipment is a pressure reducing equipment used to regulate the gas supply pressure. In the gas supply system, the pressure regulator mainly needs to reduce the gas pressure and stabilize it at an appropriate level that can make the gas safe, economical and efficient use. It is an important link in the gas transmission and distribution network to connect each process. In the operation status of these equipment and pipelines, a crucial aspect is the antifreeze and temperature maintenance of the equipment and pipelines to ensure the normal transportation of liquids in low-temperature environments. Huanrui electric heating products can automatically limit the temperature during heating and automatically adjust the output power with the temperature of the heated object without any additional equipment. They can be cut in any way without affecting use. It has a uniform temperature and will not overheat. High safety factor, pollution-free, energy-saving and environmentally friendly; When operating intermittently, it has advantages such as fast heating startup and simple installation and maintenance operations. Huanrui has always been a good choice for heat tracing and insulation of gas equipment in the new energy industry. Huanrui Electric Tracing Belt has been successfully installed in the propylene gas compressor system to provide efficient, reliable, and long service life process maintenance temperature of 90~180 degrees Celsius, temperature resistance of 200 degrees Celsius, and process maintenance temperature of 40~60 degrees Celsius, meeting temperature requirements and ensuring the reliability of pipeline operation. The Huanrui Electric Tracing System ensures that the temperature of natural gas does not decrease during equipment transportation, and on this basis, the pipeline is maintained at a temperature that is conducive to maintaining good fluidity. Ensure stable temperature transport in the harsh environment of Iran, located in arid and semi-arid climates. Huanrui has submitted an excellent transcript for this project and provided professional electric heat tracing services...
