-
摘要: 介紹了大直徑焊管生產(chǎn)用擴徑機的主要作用和主要類型,著重分析了機械式擴徑機和液壓式擴徑機所存在的優(yōu)缺點,闡明了機械式擴徑機將逐步取代液壓式擴徑機這一觀點。Abstract: The co-authors describe the main functions and types of large-size weld pipe expanding mills, discuss the advantages and disadvantages of the mechanically-operated and hydraulically operated expanders, and express the opinion that the hydraulically-operated expander will be gradually replaced by the mechanically-operated one.
