为解决大口径输水管成型加工问题,江都县轻工机械厂研制成功先进的三阶段工艺管模,成为国内唯一生产这种管模的厂家,填补了我国建材生产设备的一项空白。所谓“三阶段工艺”,是指输水管生产过程中的离心成型、绕线及喷砂养护三个工序。采用这种管模及工艺生产的输水管广泛用于市 In order to solve the problem of molding and processing of large-diameter water pipes, Jiangdu County Light Industry Machinery Factory successfully developed advanced three-stage process pipe molds, becoming the only domestic manufacturer of such pipe molds, filling a gap in China’s building materials production equipment. The so-called “three-phase process” refers to the three steps of centrifugal molding, winding and sandblasting in the production process of the water delivery pipe. Water pipes produced using this pipe mould and process are widely used in the city
