<p>PROBLEM TO BE SOLVED: To constitute a simple casing, wherein a desired pipe with a flange can be inserted on an electric cable without dismantling a connecting part body and satisfactory performance is obtained. SOLUTION: Adjacent pipes with flanges of a plurality of pipes 1(a-e) with flanges which constitute a casing are separated and isolated in the cable shaft direction, and a longitudinally split pipe 3 with a flange is interposed between the isolated parts. In the longitudinally split pipe 3 with the flange, facing surfaces in the longitudinal direction are bonded so as to have strength and airtightness identical to those of a seamless pipe, and newly bonded flange surface is made to have precision which is identical to that of a flange of a unified ring type. In the case of exchange, a part of the pipes with the flanges is dismantled and eliminated, and the longitudinally split pipe 3 with the flange is interposed in a released part by this process. In the pipe member, a bonding means having strength and airtightness which are identical to those of a seamless pipe is applied on the mating surfaces in the longitudinal direction of the longitudinally split pipe 3 with the flange.</p> |
