[Ten years of development of chemical equipment] 903-2023 The largest domestic diameter 1620 mm heating pipe

Thread Content

Chemical equipment has developed greatly in the past ten years. Praise for China's prosperity and strength in the prosperous age. It will be more lively and exciting with everyone's participation. Everyone is welcome to participate in more forum exchanges and discussions. Happy May Day! Safe and safe in May * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * On April 13, 2023, the first 1,620 mm diameter steel pipe provided by Baoji Steel Pipe was hoisted to the foundation pit at the construction site, marking the official start of the Zhengzhou Thermal Dengfeng Power Plant's "heat into Zhengzhou" project. This is the first time that the largest diameter steel pipe with high temperature resistance and heavy anti-corrosion inner coating has been used in the construction of domestic urban heating pipelines. The "Heat Diversion into Zhengzhou" project of Zhengzhou Thermal Dengfeng China Resources Power Plant is a livelihood project to alleviate the shortage of heat sources in Zhengzhou City in winter. The total investment in the project is approximately 3.24 billion yuan, and the pipeline is 60 kilometers long. It is the fifth and longest “heat-to-Zhengzhou” pipeline in Zhengzhou City so far. The high-temperature-resistant and heavy-duty anti-corrosion coating is a new anti-corrosion product developed by Baoji Petroleum Steel Pipe Pipe Co., Ltd. in 2018 by leveraging its "manufacturing + service" advantages. The use of this coating increases the maximum operating temperature of internal anti-corrosion from 80°C to 130°C, filling a gap in the domestic thermal pipeline market. In the 2018 Zhengzhou Thermal Yuneng Power Plant's heat transfer project to Zhengzhou, the transmission pipe company made careful planning, careful organization, and strict quality control to produce and supply 12,000 tons of high-temperature-resistant and heavy-duty anti-corrosion coated steel pipes with a diameter of 1,420 mm for the project in view of the difficulty in producing new products and high standard requirements.
