Preferably, the first bands are equidistantly distributed around the inner side of the middle flexible layer, the second bands are equidistantly distributed around the outer side of the middle flexible layer, and the first bands and the second bands are the same in number and are arranged in a staggered mode.
Preferably, the inner wall layer is provided with an inner wall layer embedding groove which is used for accommodating the first embedding strip and is inwards sunken on the surface of the inner wall layer which is contacted with the middle flexible layer.
Preferably, the number of inner wall panel grooves corresponds to the number of first fillets.
Preferably, the face of the outer wall layer in contact with the intermediate flexible layer is provided with an outer wall layer caulking groove which is recessed inwards and used for accommodating the second filler rod.
Preferably, the number of the outer wall layer caulking grooves is the same as the number of the second fillet.
The utility model discloses technical effect mainly embodies in following aspect: the pipe is provided with the middle toughness layer between the inner wall layer and the outer wall layer, and the two side surfaces of the middle toughness layer are respectively provided with the first embedded strip embedded with the inner wall layer and the second embedded strip embedded with the outer wall layer, so that the toughness and the pressure resistance of the pipe can be enhanced, and the service life of the pipe can be prolonged.
