结合北美成熟使用近60年的承插式柔性接口和美国水行业协会(AWWA)标准对钢管承插式接口的要求, 详细介绍了承插式接口连接的标准和规范、 管端承口和插口的设计和加工制作方法, 以及制造和安装时应注意的问题. 指出: 采用胶圈密封时, 承插连接的钢管选用螺旋埋弧焊管;在非开挖工程中采用帕姆洛克(Permalok)承插式钢管连接, 该承插式快速丝扣刚性连接钢管不需要现场焊接, 钢管选用直缝焊管.
結閤北美成熟使用近60年的承插式柔性接口和美國水行業協會(AWWA)標準對鋼管承插式接口的要求, 詳細介紹瞭承插式接口連接的標準和規範、 管耑承口和插口的設計和加工製作方法, 以及製造和安裝時應註意的問題. 指齣: 採用膠圈密封時, 承插連接的鋼管選用螺鏇埋弧銲管;在非開挖工程中採用帕姆洛剋(Permalok)承插式鋼管連接, 該承插式快速絲釦剛性連接鋼管不需要現場銲接, 鋼管選用直縫銲管.

Combined with spigot joint of non-restrained gasket connection application in North America nearly 60 years and the requirements of AWWA standard for steel pipe spigot joint, it detailedly introduced the standard and norm, the design, fabrication and installation for the joints of rolled groove type and Carnegie type,and some matters needing attention. It pointed that it should use SAW pipe for rubber gasket sealing, and adopt Permalok fast joint on longitudinal welded pipe in the trenchless application with no field welding.
