活接头(union)又叫由壬或由任,是一种能方便安装拆卸的常用管道连接件。主要有螺母,云头,平接三部分组成。由圆钢或钢锭模锻成型后机加工的管道连接件,它的连接形式分承插焊接和螺纹连接,承插焊接是将钢管插入承插孔内进行焊接,因此,被称为“承插活接头”,螺纹连接是将钢管旋入螺孔内进行连接,因此,被称为“螺纹活接头” 我公司生产的锻制管件压力等级有2000PSI.3000PSI.600PSI.9000PSI.壁厚等级代号为:SCH40 SCH80.SCH160.XXS. 主要制造标准为ASME B16.11、MSS SP 83,BS3799。 按材质来分可有:碳钢,不锈钢(304,304L,316,316L,321),合金钢(12Cr1MoV、Cr5Mo、10CrMo910、15CrMo). 活接头(由壬)参数表 (SOCKET UNION) |
