Foamed thermal insulation pipe

The utility model discloses a foamed thermal insulation pipe consisting of an outer pipe, an inner pipe, and a thermal insulation layer which fills the space between the outer pipe and the inner pipe, wherein the outer pipe and the inner pipe share the same axis center. Because the thermal insulation layer is sandwiched between the outer pipe and the inner pipe, the thermal insulation layer in sealed and cannot be damaged easily. Therefore the foamed thermal insulation pipe is advantaged by prolonged service life of the pipeline, ideal thermal insulation effects, and convenient installation construction.
