Description
「すき間付二重管」:二重管の外管内面と内管外面の金属面が機械的、冶金的に密着していない(すなわち、当該金属面が金属結合しておらず、両金属面間に僅かなすき間が存在する)、しかも適度な圧着性をもった二重管をいう。なお、前記の「圧着性」とは、外管に内管を挿入し冷間加工により圧着することにより得られた二重管における外管と内管の剥離、分離のし難さをいう。
「貫通リーク」:二重管の外管もしくは内管のいずれかに発生したクラックが進展して二重管を貫通した結果、二重管内を通過する流体が漏れ出すことをいう。
「%」:二重管等、対象物に含まれる各成分の質量百分率(質量%)を表す。
(1)高温耐熱耐圧部材として、高温強度を有すること。
(2)貫通リークを防止するためのすき間を外管内面と内管外面の間に有する二重管を、複雑な工程をふまず、容易に製造できること。
(3)管外面と管内面の間の熱伝導性が損なわれない、すなわち二重管の外管と内管の間の熱伝達が遮断もしくは著しく阻害されないこと。
(4)熱交換器管として、二重管の外管と内管が適度な圧着性をもっていること。
(5)このすき間付二重管を、高い品質(すき間の間隔が適度でばらつきが少ない、つまり均質であることを意味する)で、安定的に製造でき、かつ経済的であること。
外管内面と内管外面の間に貫通リークを防止するためのすき間を有する高品質の二重管を容易かつ安定的に製造することができる。
本発明の方法により製造されたすき間付二重管は、外管内面と内管外面の間に適正な間隔のすき間を有しており、管外面と管内面の間の熱伝導性が損なわれず、外管と内管が適度な圧着性をもっている。このすき間付二重管は、発電ボイラー、化学工業、原子力用の高温耐熱耐圧部材として使用することができ、特に、将来の高速増殖炉の蒸気発生器管として好適である。
外管:外径20.4mm、肉厚1.9mm、長さ15m
内管:外径15.7mm、肉厚1.6mm、長さ15m
製造した二重管のすき間の間隔は、管の円周方向断面の5箇所で、光学顕微鏡観察により各5点づつ測定して平均した値を範囲として示した。
手順:
1)管全体をヒーター等で加熱して所定の温度にする。
2)管内面に水を流し、入り側と出側の水の温度を測定する。
3)水の温度差が得られた熱量であり、この熱量が管壁から得られたものと見なし、二重管の熱伝導度を求める。
さらに本発明で製造した二重管について、内圧クリープ試験を実施し、二重管の破断強度がそれぞれの単管強度にほぼ等しいことを確認した。
