概要:
当社の福山製鉄所ならびに京浜製鉄所の溶接管工場において製造される各種高性能鋼管は，インフラストラクチャー整備，高性能自動車用途などの多様な用途に広く用いられてきた。さらなる次代のニーズに応えるべく，各種高性能ラインパイプ，建築土木用鋼管，ハイドロフォーミングプロセス適合鋼管などを開発した。本稿では，適用の拡大が期待される開発鋼管の特徴とその製造方法などについて紹介する。
Abstract:
Wide varieties of high performance steel pipes
for infrastructure and automobile usages have
been manufactured in UOE and ERW mills of
Fukuyama and Keihin works for many years.
High performance linepipes such as high strength
corrosion resistance, high deformability structural
pipes and ERW pipes suitable for hydoforming
process have been developed for needs expected
to come in near future. Characteristics of
these steel pipes and some features of manufacturing
process are introduced in this paper.
