Background
The thermal power plant is a thermal power plant which utilizes the extraction or exhaust of the steam turbine to supply heat for users while generating electricity. The main working principle is that hot water generated after power generation of a thermal power plant is utilized and is heated again for heating. Therefore, a large number of steam pipelines are arranged in the thermal power plant area to convey steam to provide driving force for a steam turbine or to provide heating for residents. In order to ensure the sufficient driving force and long-distance delivery of the steam, the steam is pressurized, and meanwhile, the heat-insulating material is wrapped on the pipeline along the way to prevent the consumption of steam energy in the pipeline.
The company discovers that the position of a connecting pipe opening of a steam pipeline is connected in the daily maintenance process because most pipelines are connected in a mode that flanges are sealed with gaskets. The sealing gasket is easy to generate thermal oxidation aging under high-temperature and humid environments, so that the sealing performance of the pipeline interface is reduced. Over time, steam leakage problems can occur, resulting in a drop in steam pressure within the pipe. Secondly, because the flange interface at the connecting pipe opening is exposed outside, the heat-insulating layer is difficult to lay, and the protruded flange plate accelerates the heat loss at the position, so that the heat of the steam is wasted. Moreover, the flange interface with leakage points is difficult to replace in time during the conveying process of the steam. Resulting in the waste of only a whitish amount of heat and pressure of the steam in a short period of time. This is contrary to the concept of "energy reduction and consumption reduction".
