The detachable insulation structure of the steam turbine body is assembled in multiple pieces and adopts a buckle connection structure. Each piece is relatively independent, and the protective layer is made of stainless steel or color steel plate using a special process. The insulation layer is an independent insulation block structure that can be reused multiple times. Therefore, the detachable insulation structure of the steam turbine body is easier to disassemble during equipment maintenance.

The installation and construction of traditional steam turbine insulation structures takes 10 days, while dismantling during major repairs takes 2 days and cleaning takes 1 day. In this way, for each disassembly and assembly, the insulation construction cycle will take 13 days. When using the detachable insulation structure of the steam turbine body for major repairs, dismantling only takes 1 day, and insulation installation only takes 4 days. Therefore, each major overhaul can save at least 8 days of time, greatly shortening the construction cycle.

Because insulation construction cannot cross operate with other construction processes except for cleaning, the time taken for disassembly and installation is actually the effective operating time of the equipment. So adopting a detachable insulation structure for the steam turbine body can greatly improve the equipment operation rate, thereby bringing good economic benefits to the enterprise.
