卡套式管接头由三部分组成：接头体、卡套、螺母。当卡套和螺母套在钢管上插入接头体后，旋紧螺母时，卡套前端外侧与接头体锥面贴合，内刃均匀地咬入无缝钢管，形成有效密封。

　　The bayonet type pipe joint consists of three parts: the joint body, the bayonet and the nut. When the clamp sleeve and nut sleeve are inserted into the joint body on the steel pipe and the nut is tightened, the front and outside of the clamp sleeve are fitted with the taper surface of the joint body, and the inner edge evenly bites into the seamless steel pipe to form an effective seal.

　　卡套接头的装配

　　1、锯下合适长度的无缝钢管，去除端口毛刺。钢管端面要与轴线垂直，角度公差不大于0.5度。如果钢管需要折弯，则钢管端面至弯曲部位的直线段长度不能少于三倍螺母的长度。

　　2、把螺母和卡套套在无缝钢管上。注意螺母和卡套的方向，不要装反了。

　　3、在预装配接头体螺纹和卡套上涂上润滑油，把钢管插入接头体，（钢管一定要插到底）用手旋紧螺母。

　　4、拧紧螺母直至卡套卡住钢管，这个转折点可以通过拧紧力矩的增加感受到（压力点）。

　　5、达到压力点后，再将螺母拧紧1/2圈。

　　6、将预装配接头体拆下，检查卡套刃边的嵌入情况，可见的突起带必须填满卡套前端的空间。卡套可以稍微旋转，但不能轴向移动。

　　7、最终安装，将实际安装中的接头体的螺纹涂上润滑油、压紧螺母与之配合拧至可感觉到的拧紧力增加为止，接着再拧紧1/2圈安装完毕。

　　Assembly of bayonet joint

　　1. Saw off the seamless steel pipe of appropriate length to remove the burr of the end. The end surface of the steel tube shall be perpendicular to the axis, and the Angle tolerance shall not be greater than 0.5 degree. If the steel pipe needs to be bent, the straight segment length from the end face of the steel pipe to the bending part shall not be less than three times the length of the nut.

　　2. Put the nut and clip sleeve on the seamless steel pipe. Pay attention to the direction of the nut and clamp, do not install the reverse.

　　3. Lubricate the thread and clamp sleeve of the preassembled joint body, insert the steel pipe into the joint body, (the steel pipe must be inserted to the end) tighten the nut by hand.

　　4. Tighten the nut until the steel pipe is stuck by the clamp sleeve. This turning point can be felt (pressure point) by increasing the tightening torque.

　　5. After reaching the pressure point, tighten the nut 1/2 turn.

　　6. Remove the preassembled connector body, check the insertion of the edge of the card sleeve, and the visible protrusion belt must fill the space of the front end of the card sleeve. The sleeve can be rotated slightly but does not move axially.

　　7. For final installation, the thread of the joint body in actual installation shall be lubricated and the compression nut shall be screwed together until the perceived tightening force is increased, and then the installation shall be completed by tightening 1/2 circle.
