Zusammenfassung: | PURPOSE:To produce a lining pipe without spoiling the corrosion resistance of a lining material formed in a cylindrical shape by putting base metals in a split construction to said material then welding the base metals to each other. CONSTITUTION:The lining material 1 is formed to a prescribed cylindrical shape. A commercially marketed elbow is longitudinally split to produce base metallic pieces 3. The pieces 3 are put on the material 1 and a backing strip 5 consisting of a heat resistant material such as ceramic tape is inserted to the inside in the joint part of the pieces 3, 3. The pieces 3 which are held inserted with the strip 5 are integrally welded. The strip 5 is then removed. |
