Ultrahigh molecular weight polyethylene heat preservation composite pipe

The utility model provides an ultra-high molecular weight polyethylene heat preservation composite pipe which comprises a composite pipe body, the composite pipe body comprises an inner-layer pipe body and an outer-layer pipe body, and the outer-layer pipe body and the inner-layer pipe body are arranged in a matched mode. According to the ultra-high molecular weight polyethylene heat preservation composite pipe, the ultra-high molecular weight polyethylene inner pipe has the advantages of being good in impact resistance and corrosion resistance and the like, the composite aerogel felt layer has good heat preservation performance and can effectively prevent heat loss, and the poly aldehyde ether pipe protection layer is high in strength, resistant to high temperature and high pressure and good in heat preservation performance. The inner structure of the pipeline can be effectively protected, so that the composite pipe body can meet the requirements of heat preservation of a ground source heat pump in the geoth
