Description
即ち、前記したスチール製の燃料圧送配管に例えば引抜き伸管材を用いる場合、管内周面には引抜き伸管時に発生した初期疵(微細クラックやしわ疵等)が存在し、又、溶接管の場合には管内周面に溶接不良等により発生した初期疵(溶接欠陥部等)が存在している。このような管内周面の欠陥、特に微細クラックやしわ疵、溶接欠陥部が存在した状態で前記した内表面処理(例えばNiめっき等)が施された場合、その微細クラックやしわ疵、溶接欠陥部の内部までめっき液が浸透せず、微細クラックやしわ疵、溶接欠陥部の部位が完全に表面処理が施されず欠陥となり、特に腐食性燃料に対する耐性が得られなくなり腐食や錆の発生を余儀なくされるという問題がある。
又、管材の管内周面の初期疵(微細クラックやしわ疵、溶接欠陥部等)の除去手段に深穴加工に用いるガンドリル加工機を用いることにより、刃の直進性が良好であるため管材の管軸方向及び円周方向に均一に切削することが可能となり初期疵を完全に除去することができる。
[実施例1~6]
本実施例におけるスチール製引抜き伸管材の耐食性試験を下記要領で行った結果を表1に示す。
・耐食性試験:
管内面全体にNiめっきが施された各スチール製引抜き伸管材内に、腐食性燃料(20%アルコール混合燃料(ガソリン)、有機酸500ppm、水分5%、塩素10ppmを含む)を封入して、温度100℃で1000時間放置した時の管内の腐食状況を確認した。耐食評価は、赤錆の有無を目視及び実態顕微鏡にて確認して判定した。
[従来例1~3]
一方、従来例1~3は、いずれも引抜き伸管材の内周面に赤錆の発生が見られ、本発明のスチール製引抜き伸管材に比べて耐食性が劣ることが判明した。
本実施例におけるスチール製溶接管材の耐食性試験を実施例1と同じ要領で行った結果を表2に示す。
