川崎製鉄の鋼管製造技術の現状

Recent Progress in Pipemaking Technology Developed by Kawasaki Steel Corporation 佐山 泰弘(Yasuhiro Sayama) 要旨 : 川崎製鉄の鋼管製造は1952 年に始まり,現在千葉製鉄所および知多製造所に集約されてい る。当社における鋼管生産量比率は約 12%であり,当社の主要製品の一つである。鋼管技 術は国内・海外のエネルギー開発分野,建築・建設分野をはじめあらゆる分野での発展と 関係が深い。このたび,鋼管特集号の発刊に際し,最近の川崎製鉄における鋼管製造技術 の進歩について,鋼管工場での製造技術および新製品開発,さらに鋼管関連技術として製 品の検査や使用性能評価を試験する技術等について概説した。 Synopsis :

Kawasaki Steel Corp. has been manufacturing pipe and tubes since 1952, and production has been intensively carried out at two plants namely, integrated Chiba Works and Chita Specialty Works. The steel product mix of pipe and tubes in approximately 12 per cent, and constitutes main production item in KSC. Pipe-making technology has been developed along with the progress in all kinds of fields, especially the fields of energy development, architecture and construction. Taking an opportunity of the Special Issue of Steel Pipe, this paper describes the recent progress in tubular products and techniques in KSC such as pipe-making process technology, newly developed products and sophisticated inspection technique of evaluation for practical purposes.
