本文着重介绍西班牙 Amurrio 厂 CPE 机组的主要设备及其性能。该 CPE 机组是由6″顶管机组改造而来的,试生产表明,它在降低金属消耗、改善壁厚公差、减轻顶管机负荷等力面比传统顶管机组更加优越;同时,该机组还保留了顶管生产技术难度低、适合生产薄壁管、投资较低等特点。文章指出,CPE 工艺对中小型无缝钢管技术改造,特别是对顶管机组进行技术改造更具有较大价值。
This article highlights the main equipment and performance of the CPE unit in Amurrio, Spain. The CPE unit is a retrofit from a 6 "pipe jacking unit. Pilot production shows that it is superior to conventional pipe jacking units in reducing metal consumption, improving wall thickness tolerances and reducing pipe jacking load. At the same time, the unit But also retains the top pipe production technology is low in difficulty, suitable for the production of thin-walled tubes, low investment and other characteristics.The article points out that the CPE technology for small and medium-sized seamless steel pipe technology innovation, especially for pipe jacking units for more technical transformation of greater value .
