牛头牌镀锌管简介

热镀锌钢管经过20世纪60~70年代的发展,产品质量得到了很大的提高,1981~1989年连续被评为冶金部优质产品及国家银质奖等,产量也连续多年增长,1993年产量为40多万吨,1999年产量为60多万吨,并出口东南亚、非洲、美国、日本、德国等国家和地区。热镀锌管多用作输水管和煤气管,常用规格为+12.5~+102 mm。90年代以后,由于国家对环境保护的重视,对高污染企业控制越来越严,热镀锌管在生产中产生的“三废”难以解决,再加上不锈钢焊管、PVC管和复合管等管材的快速发展,以及国家提倡推广应用化学建材,限制使用镀锌钢管,使得热镀锌焊管的发展受到了很大的约束和限制,热镀锌焊管后来发展缓慢 


牛头牌镀锌管与电镀管的区别

为提高钢管的耐腐蚀性能,对一般钢管进行镀锌。镀锌钢管分热镀锌和电镀锌两种,热镀锌镀锌层厚,电镀锌成本低,表面不是很光滑。吹氧焊管:用作炼钢吹氧用管,一般用小口径的焊接钢管,规格由3/8-2寸八种。用08、10、15、20或者195-Q235的钢带制作成的,为了防腐蚀,有的要进行有效渗铝处理。
