The present invention relates to an expansion pipe and a method for manufacturing the same. The expansion pipe includes flange connection units (10,10') and a convex expansion unit (20) formed between the flange connection units (10,10'). The expansion unit (20) includes a first heat-resisting rubber layer (21) located on the inner circumference coming into contact with a fluid; a reinforcing layer (22) piled up on the outer circumference of the first heat-resisting rubber layer (21); a second heat-resisting rubber layer (23) piled up on the outer circumference of the reinforcing layer (22); an insulation layer (24) piled up on the outer circumference of the second heat-resisting rubber layer (23); and a third heat-resisting rubber layer (25) piled up on the outer circumference of the insulation layer (24). |
