A high-performance steam insulated pipeline is disclosed. The high-performance steam insulated pipeline comprises a steam pipeline used for transporting steam, the steam pipeline is at least wrapped with an aluminium silicate layer and a rock wool layer, a reflective glass fiber film is arranged between the aluminium silicate layer and the rock wool layer in a coating mode, and layered sealing is conducted outside the aluminium silicate layer by using an aluminum foil sealing band; the external surface of the rock wool layer is also coated with a reflective glass fiber film, and layered sealing is also conducted outside the rock wool layer by using an aluminum foil sealing band; the rock wool layer is further wrapped with a thick flat glass fabric, and layered sealing is conducted outside the thick flat glass fabric by using an aluminum foil sealing band; and finally, the outermost layer is wrapped with a color plate. At least one layer of reflective glass fiber film is arranged on the external wall of the steam pipeline in a coating mode in advance. The high-performance steam insulated pipeline has the characteristics that the structural composition is reasonable, usage and installation are convenient, the reliability is good, the heat loss of the steam pipeline can be reduced, and the thermal insulation performance of the steam pipeline is enhanced remarkably.
