建筑给水薄壁不锈钢管材和管件均含铬(Cr)量在12%以上,并按需要添加其他金属元素所形成的奥氏体晶体结构性质的铁合金。添加镍(Ni)可提高材料的延展性和韧性,使加工易成型,宜弯曲。减少碳(C)含量,可提高材料的焊接性能。添加钼(Mo)或锰(Mn)等含量,可提高材料的耐点蚀和耐缝蚀的性能。
薄壁不锈钢管管材中铬与氧气、氧化剂反应后,产生钝化作用,在表面形成一层薄而坚韧的致密钝化膜Cr2O3,起抗腐蚀的保护覆膜作用。
不锈钢管材、管件若经去杂、酸洗、钝化工艺处理后,可使生成的Cr2O3的厚度增加,致密的均匀性增强;不锈钢管经抛光、管件经精光工艺,不仅能消除表面缺陷,还使钝化膜更为细腻、致密,以减少点腐蚀的概率。同时,管件精光后内壁光洁、摩阻小,进一步提高管材的水力性能,节约消耗。
不锈钢管具有强度高,抗腐蚀性能强、韧性好,抗振动冲击和抗震性能优,低温不变脆,输水过程中可确保输水水质的纯净,且经久耐用又可再生做装潢材料利用。——金时通管:一次选择,一生管用!
