Description

【発明の詳細な説明】 本発明は塩ビライニング鋼管のフランジ溶接方法に関す
るものである。
従来、大口径の塩ビライニング鋼管を接続するには、（
１）管端部内側の塩ビ管の切断、（２）切断塩ビ管の撤
去、（３）フランジ溶接、（４）補修塩ビ管の挿入，（
５）盲フランジによる補修塩ビ管の押付け（２４時間）
の５工程が必要である。
本発明は大口径の塩ビライニング鋼管にフランジを溶接
するのに要する時間を大幅に短縮し、補修塩ビ管を不要
にすることのできるフランジ溶接方法の提供を目的とす
るものであって、その目的を達成する手段として、塩ビ
ライニング鋼管の管端にフランジを溶接するに当って、
該塩ビライニング鋼管内に注水しながら溶接箇所を冷却
するようにしたものである。
以下、図面を参照して本発明を詳細に説明する。
図中において、１は塩ビライニング鋼管であり、２はフ
ランジであり、３は溶接である。
４は管体支持台であって、塩ビライニング鋼管１を回転
可能に、かつ傾斜させて支持するように構成してある。
５は低い方の側の管端９に着脱可能に装着した木栓であ
って、通水穴６を備えている。
７はホースであって塩ビライニング鋼管１内に水８を注
入することによって、フランジ溶接箇所を冷却するよう
になっている。
塩ビライニング鋼管１の一方の管端９に木栓５を装着し
、図示のように塩ビライニング鋼管１を管体支持台４に
回転可能に、かつ管端９が下方になるように傾斜させて
支持し、次いでフランジ２を管端９に仮装着し、ホース
７にて管１内に水８を図示のように注入しながら溶接箇
所冷却するとともに、塩ビライニング鋼管１を回転しな
がらフランジ２を溶接すると、溶接によって内側の塩ビ
管１′が加熱されるも、水８によって冷却され、かつ水
８は通水穴６から流出するとともにホース７から絶えず
注水されているので、溶接中に塩ビ管１′は損傷を受け
ることがない。
管端９におけるフランジ溶接終了後は注水を停止し、木
栓５を取外して、管端９′に装着し、以下前記の要領に
よって管端９′にフランジを溶接するのである。
以上の説明によって容易に理解できるように、本発明に
よるときは、フランジ溶接中に溶接部における塩ビ管を
冷却水によって冷却し、損傷を防ぐことができるので、
従来のようにフランジの溶接に先立って、管端部内側の
塩ビ管の切断および切断塩ビ管の撤去作業が不用であり
、このことによって、フランジ溶接後における補修塩ビ
管の挿入および盲フランジによる補修塩ビ管の２４時間
にわたる押付け作業も不用となり、大口径の塩ビライニ
ング鋼管のフランジ溶接時間を大幅に短縮し、補修塩ビ
管を不用にすることができるのである。
