5-10. 円形鋼管の製造可能範囲と断面性能表

UOE, プレスベンド鋼管製造可能範囲

注： 1. 2. 3. 4.

規格・サイズ・製法により製造可能長さは異なります。UOE：min.11.1m～max.13.5m（造管max.18.0m）、プレスベンド：min.3.0m～max.12.0m UOE鋼管製造可能範囲内の鋼管においても、造管精度、歩留、サイズ別数量などを考慮し、プレスベンド鋼管で製造することがあります。「ご相談受付サイズ」は、製造頻度の低いサイズのため、あらかじめ弊社にご相談いただき、納期等の調整をお願いします。上記鋼管は、原則、1シーム鋼管ですが、鋼管外径が大径となると、2シームで造管することもあります。

5. 6. 7. 8.

UOE鋼管は、外径によって納期が大きく異なります。ご注文の際には必ずお問い合わせください。鋼管の寸法精度は、原則JIS規格もしくは大臣認定規格によります。ご要望の寸法精度がこれらより厳しい場合、別途ご相談ください。鋼管の化学成分・機械的性質の保証値は、JIS規格もしくは大臣認定規格によります。その他性能についてご要望の場合は、別途ご相談ください。上記範囲内におけるインチサイズ及び中間サイズに関してはご相談下さい。
