Flame-retardant threading pipe with insulation function

The utility model discloses a flame-retardant threading pipe with an insulation function, and relates to the technical field of decoration materials. The pipe comprises a pipe body and a fixing assembly, a protective net layer is fixedly arranged on the inner surface of the pipe body, a flame-retardant layer is fixedly arranged on the inner side of the protective net layer, a rubber layer is fixedly arranged on the inner side of the flame-retardant layer, the rubber layer is made of polyethylene materials, and an epoxy glass cloth layer is fixedly arranged on the inner side of the rubber layer. The protective net layer is formed by weaving the metal wires in a rhombic structure, the rhombic protective net layer not only has a good shielding effect, but also greatly improves the tensile property of the pipe body, the flame-retardant layer can play a flame-retardant role, and the rubber layer is made of polyethylene materials and can resist erosion of most of acids and bases. The epoxy glass cloth layer enables
