Abstract
A conduit (100) comprising a plurality of conduit segments (112A–112C) each having a body (120A–120C) and a segment lining (136A–136C) made of a lining material. Each body includes a joint face (132A–132C) having secured thereto a portion (140A–140C) of the corresponding segment lining. A monolithic lining (108) is formed from the segment linings by abutting the conduit segments with one another so that the joint faces face one another and the portions of the segment linings contact one another. The portions of the lining on the joint faces are heated to a temperature above the melting point of the lining material so that they fuse with one another so as to form a fusion (148A, 148B) located between the joint faces.
