[0002] Boilers are commonly used devices in industry and daily life, and their main function is to heat water into steam or hot water to provide energy. If a boiler fails, it will affect its normal work, leading to energy waste and reduced production efficiency. Regular maintenance can help to find and solve problems in time, thereby improving the operation efficiency of the boiler. During the process of overhauling the boiler, a pipeline fixing device is needed to control the pipeline to avoid its deviation caused by overhauling.
