随着寒带、海底油田及天然气田的开发,输送管线设计中,其长度和直径显著增大,随此,钢管的需要量也增加。住友金属工业公司为了适应这种大直径管线的需要,自1970年以来,就建造了 U—O 成型焊管设备。工程投资费用为160亿日元。这台设备的制管尺寸和生产能力均是同类设备中最大的。其生产能力为36万吨/年,可生产的钢管尺寸:外径是609.6～1625.6毫米(64时),壁厚是6.35～30毫米(X65硬度的最大壁厚是25.4毫米),长度为18.3米。
With the development of boreal and submarine fields and natural gas fields, the length and diameter of pipelines have increased significantly in the design of pipelines. As a result, the demand for steel pipes has also increased. In order to meet the needs of this large-diameter pipeline, Sumitomo Metal Industries Co., Ltd. has built U-O forming pipe equipment since 1970. Project investment costs 160 billion yen. The pipe size and production capacity of this equipment are the largest of its kind. Its production capacity is 360,000 tons per year. Pipe sizes available: 609.6 to 1625.6 mm (64 in outside diameter), 6.35 to 30 mm wall thickness (maximum wall thickness of 25.4 mm for X65 hardness) and a length of 18.3 Meter.
