ABSTRACT:
A lined tubular assembly and a method and apparatus for lining an elongated tubular article to form the assembly. The lined tubular assembly has a metal tube with a non-metallic liner bonded to the internal surface thereof by a bonding agent. A non-metallic flanged end piece is secured to each end of the metal tube and has a first portion extending into the tube between the liner and the internal surface of the tube and a second portion covering the end surface of the tube. The method for producing the assembly includes introducing simultaneously into the tubular article both a tubular liner and a bonding agent for bonding the liner to the internal surface of the tubular article. The apparatus for producing the assembly includes an elongated liner installation device that simultaneously introduces the liner and bonding agent to the interior of the tubular article.
