Supporting and protecting assembly for high-temperature pipeline

The utility model relates to the field of pipelines, in particular to a supporting and protecting assembly for a high-temperature pipeline, which comprises a soft heat preservation layer (1), a hard heat preservation layer, a metal plate layer (3) and a pipe clamp assembly which are sequentially distributed from inside to outside. The pipe clamp has the advantages that the pipe clamp is good in high-temperature resistance and heat insulation effect, the plurality of hard heat insulation layer modules are arranged, soft heat insulation materials are arranged at the joints of the modules, buffering performance is achieved through matching of the hard heat insulation layers and the soft heat insulation materials, the metal sheet layer is in a curled adjustable state, and the fastening piece of the pipe clamp is provided with a spring for buffering and adjusting tightness. According to the scheme, the tightness of the pipe wall protection assembly can be automatically adjusted in the thermal expansion and cold co
