TUBULAERT ELEMENT SOM HAR EN FORING OG FREMGANGSMAATE FOR AAFORE ET TUBULAERT ELEMENT.

摘要

A tubular member having a liner adhesively affixed to an inner surface thereof. The liner (10) comprises a porous material (16) formed from a plurality of needle-punched unwoven fibers (18) so as to have a pair of oppositely facing surfaces (20,22). The liner (10) also includes a first mat (24) of finespun woven filaments of glass defining an inner surface (10a) thereof and a second mat (26) of finespun woven filaments of glass defining an outer surface thereof (10b). The inner and outer surfaces (10a,10b) of the liner, formed by the first and second mats, are generally coextensive with the porous material (16). The liner (10) also includes the first (24) mat being secured to an inwardly facing surface of the porous material and the second mat being secured to an outwardly facing surface of the porous material. The liner is adhesively impregnated so as to adhesively bond the outer surface of the liner to the inner surface of the tubular member. Further, a method of lining a tubular member by adhesively bonding a liner to the tubular member is disclosed.
