1984年第一套CPE无缝钢管机组在西班牙投产.该机组包括1台2辊穿孔机和1台连续轧管机,用于生产直径达178mm,壁厚达12.5mm的钢管.钢管的壁厚不均为5～6%,使用的管坯重达1400公斤,年产钢管25万吨.可以认为,该机组的主要优点有:基建投资不大;可轧制较长的厚壁??薄壁钢管.机组的设备由西德曼内斯曼-德马克公司制造.在改造中,CPE机组取代了齿条式顶管机组.
The first CPE seamless tube unit was commissioned in Spain in 1984. The unit consisted of a 2-roll perforator and a continuous tube mill for the production of steel pipes up to 178 mm in diameter and 12.5 mm in wall thickness. Uneven 5 to 6%, the use of the tube weighs 1,400 kg, with an annual output of 250,000 tons of steel pipe can be considered, the main advantages of the unit are: capital investment is not large; can be rolled longer thick thin Wall pipe.The equipment of the unit was manufactured by Sidley Mannesmann-Demark, in which the CPE unit replaced the rack and pinion unit.
