株洲市矿筛厂经过两年多的艰苦努力,成功地设计制造了具有中国特点的第一批全焊式不锈钢筛管,经胜利油田油井的防沙实验,各项技术指标完全达到设计要求,为我国油井挠丝筛管砾砂充填防沙工艺,大型热电站过滤系统中采用全焊式不锈钢筛管作滤管的工艺作出了贡献。株洲市矿筛厂设计制造成功的全焊式不锈钢筛管是采用目前国际上较新的科学技术,筛管开口率、缝隙均匀度、外表光洁度接近美国贝克尔公司同类产品。这种筛管质量好,使用性能稳定
After more than two years of hard work, Zhuzhou Mine Sieve Factory succeeded in designing and manufacturing the first batch of all-welded stainless steel screen with Chinese characteristics. Through the sand prevention experiment of wells in Shengli Oilfield, various technical indexes fully met the design requirements, For China’s well silty sand screen filled silt sand filling process, large-scale thermal power plant filtration system using all-welded stainless steel screen for the filter tube made a contribution to the process. All-welded stainless steel screen designed and manufactured by Zhuzhou Mine Sieve Factory adopts the newest international science and technology. The opening ratio of screen pipe, the evenness of gap and the appearance finish are similar to the similar products of American Becker company. This screen of good quality, stable performance
