世界上第一台狄塞尔轧管机于1935年投产使用。尽管这种轧管机可以轧制同心度好、表面质量高的钢管,变换壁厚也比较方便,但因其生产能力低,所轧钢管外径小、长度短,因而没有得到广泛应用。但是,近年来狄塞尔轧管机已经有了新的发展。西德KOCKS公司在英国钢管公司的狄塞尔轧管 The world’s first Diesel pipe mill put into operation in 1935. Although this type of pipe rolling mill can be rolled with good concentricity and high surface quality steel pipe, it is more convenient to change the wall thickness. However, because of its low productivity, the outer diameter of steel pipe is small and the length is short, so it has not been widely used. However, there have been new developments in Diesel duckers in recent years. West Germany KOCKS pipe in the British company Diesel rolling
