In response to the various issues of the sleeve compensator, such as its inability to withstand high temperatures, easy leakage, and limited application range, our company has, after years of research, developed the HF-MHB type sleeve compensator. This product features a stainless steel thin plate lining the core tube and a composite high-temperature resistant flexible graphite sealing filler, which has very low frictional resistance. Currently, it is the most advanced sealing material in China, with a maximum operating temperature of up to 450℃. The core pipe and the outer shell are made of composite ceramic steel pipes, which are used for various wear-resistant and corrosion-resistant process pipelines. The wear resistance is more than 30 times that of ordinary steel pipes. For such products applied in directly buried pipe sections, our company can provide prefabricated insulation.
