The invention provides a heat-resistant and thermal-insulated composite delivery pipe and its forming method. The composite delivery pipe includes: an inner layer with a central bore; a first reinforcement layer coated on the outer wall of the inner layer and provided with circumferential reinforcing members extending in the circumferential direction; an outer layer sleeved outside the inner layer; a second reinforcement layer coated on the inner wall of the outer layer and provided with longitudinal reinforcing members extending in the axial direction; and a thermal insulation layer sandwiched between the inner layer and the outer layer. The heat-resistant and thermal-insulated composite delivery pipe has sufficient rigidity and structural stability in both circumferential and axial directions, effectively preventing deformation and interlayer delamination.
