Metallurgically bonded clad pipe vs. Mechanical method

In the metallurgically bonded process, the cladding is bonded with a base metal pipe through a rolling/pressing process (Hot Roll Bonding (HRB)). With mechanically bonded clad pipe the cladding is mechanically attached to the base metal pipe using two different methods: 1) cladding, in the form of a pipe, is telescopically inserted into the base metal pipe and then mechanically or hydrostatically expanded, or 2) using the weld overlay method, cladding is welded to the surface of the base metal pipe.
