Further improved as of the present utility model, the thickness of foam aluminum tube is more than twice of aperture.

It is using the beneficial effect of above-mentioned technical proposal：Certain thickness ensures that there is certain density the inside of foam aluminum tube Closed pore, so as to ensure sound insulation, heat insulation effect.

Further improved as of the present utility model, the ratio between thickness of thickness and multiple tube entirety of foam aluminum tube is 1: 4 to 1: 6.

It is using the beneficial effect of above-mentioned technical proposal：Control the foam aluminum tube thickness proportion overall with multiple tube so that While some strength is kept, foam PAP also possesses the effect of bending.

Further improved as of the present utility model, possess butt-welded solid-section on foam aluminum tube.

It is using the beneficial effect of above-mentioned technical proposal：Solid-section does not have hole, increases butt-welded contact area, carries High welding effect.

Further improved as of the present utility model, the bearing of trend of solid-section is parallel to foam PAP itself Axis direction.

It is using the beneficial effect of above-mentioned technical proposal：Butt welding seam shape is simple, is easy to weld.

Further improved as of the present utility model, inner tube, outer covering layer are crosslinked polyethylene material, inner glue layer, outer glue Layer is PUR material.

It is using the beneficial effect of above-mentioned technical proposal：The intermolecular structure of crosslinked polyethylene is more stable, and structure is more firm.Heat The use good manufacturability of melten gel, has fabulous adhesive property, uniform coating thickness, surfacing to polyethylene, aluminium.

Further improved as of the present utility model, the inner side and outer side of foam aluminum tube is provided with hollow out aluminum pipe, hollow out aluminium The surface of pipe is provided with honeycomb structure.

It is using the beneficial effect of above-mentioned technical proposal：The inner side and outer side increase hollow out aluminum pipe of foam aluminum tube, improves knot Structure intensity.
