1·For compression end connection, first slide compression nut onto copper tube, then slide on ferrule.
对于压缩端口连接，首先将压缩螺母移动到铜管上，然后装上套圈。
2·Tube fittings shall be flare less compression type of three-piece construction consisting of ferrule nut and body suitable for use on ss tubes.
管道管件应为非扩口压缩式三件构造，由套圈、螺帽和本体组成，适宜安装在不锈钢管道上。
3·Using the DEFORM software, the simulation model was established and analyzed, the feasibility and the superiority of the closed type cold rolling with pair taper ferrule were justified.
运用DEFORM软件建立仿真模型进行模拟分析，对圆锥套圈的成对闭式冷辗扩的可行性和优势进行了验证。
4·Another ferrule that is used to enclose the wrist and antebrachium is linked to the crossbar of the U-shaped rack through elastic strings.
一用于腕臂套置的腕臂套圈通过弹力带连接在U形前支架的横杆上。
5·A ferrule type, flareless fitting is provided that may optionally be pulled-up to its assembled condition by torque rather than by turns.
提供一种套圈式无扩口管接头，该管接头可以通过扭转而不是通过转动随意地接上到它的装配好的位置。
