<p>PURPOSE:To connect an end part of the pipe where the lengthwise body is inserted airtightly with high reliability and high accuracy by arranging connecting pipes concentrically with pipe parts of pipes, arranging the lengthwise body between end parts, and connecting the pipes and the connecting pipes by moving the connecting pipes and also connecting the connecting pipes with each other. CONSTITUTION:The connecting pipes 11 and 12 are arranged concentrically with end parts of a couple of facing pipes 8 and 8a at the outer or inner periphery of the end parts of the pipes 8 and 8a before the lengthwise body is arranged between the end parts, and the lengthwise body is arranged in this state between the end parts by connection, etc. Then the connecting pipes 11 and 12 are extended like a telescope and moved to an interval L1. In this state, the pipes 8 and 8a and connecting pipes 11 and 12 are connected and the connecting pipes 11 and 12 are connected to each other. Consequently, the end parts of the pipes 8 and 8a are connected airtightly with high reliability and high accuracy by using the connecting pipes 11 and 12.</p> |
