活接頭(union)又叫由壬或由任,是一種能方便安裝拆卸的常用管道連接件。主要有螺母,云頭,平接三部分組成。由圓鋼或鋼錠模鍛成型后機(jī)加工的管道連接件,它的連接形式分承插焊接和螺紋連接,承插焊接是將鋼管插入承插孔內(nèi)進(jìn)行焊接,因此,被稱為“承插活接頭”,螺紋連接是將鋼管旋入螺孔內(nèi)進(jìn)行連接,因此,被稱為“螺紋活接頭” 我公司生產(chǎn)的鍛制管件壓力等級有2000PSI.3000PSI.600PSI.9000PSI.壁厚等級代號為:SCH40 SCH80.SCH160.XXS. 主要制造標(biāo)準(zhǔn)為ASME B16.11、MSS SP 83,BS3799。 按材質(zhì)來分可有:碳鋼,不銹鋼(304,304L,316,316L,321),合金鋼(12Cr1MoV、Cr5Mo、10CrMo910、15CrMo). 活接頭(由壬)參數(shù)表 (SOCKET UNION) |
