某新建污水处理项目,其V形滤池混凝土滤板固定,采用栓压方式,螺栓为不锈钢螺栓,预埋在现浇混凝土滤梁上。不锈钢螺栓安装要求:中心位置允许偏差±1mm,螺栓顶部标高允许偏差0~10mm,严禁与普通碳钢接触或焊接。一、不锈钢螺栓的特性固定滤板的不锈钢螺栓,长期浸泡在加有酸碱物质的水中,这种水溶液可以说是很好的导电介质,所以,对不锈钢螺栓抗腐蚀性能要求很高。
A new sewage treatment project, the V-shaped filter concrete filter plate fixed, the use of bolt pressure, bolts of stainless steel bolts, embedded in the cast-in-place concrete filter beam. Stainless steel bolt installation requirements: Center position tolerance ± 1mm, the top of the bolt allowable deviation 0 ~ 10mm, non-contact or welding with ordinary carbon steel. First, the characteristics of stainless steel bolts Fixed stainless steel bolts filter plate, long-term immersion in the water with acid-base substances, this aqueous solution can be said to be a good conductive medium, therefore, the corrosion resistance of stainless steel bolts demanding performance.
