The inner wall reinforced pipe (1) has a reinforced portion (3) that is exposed to increase loads in relation to a residue pipe. A tubular element (2) is arranged non-positively interacting with the inner wall of the reinforced portion of the pipe. The reinforced portion of the pipe has a reduced outer diameter as a result of plastic deformation and is arranged to tubular element with yield strength which is greater than the outer pipe. The reinforced portion is plastically deformed and arranged to tubular element. An independent claim is included for a method for manufacturing inner wall reinforced pipe. |
