顶部和底部止动坐落接头提供了生产管柱中流量控制装置的位置。坐落接头的止动轴肩用于帮助定位和锁紧流量控制装置。作业完成后，可直接上提回收。

顶部止动坐落接头的设计仅适用于顶部止动型流量控制装置，其带有与阀座短节相同的字母名称，无论是CS-AF型、CS-HF型，还是极端型，取决于所需的压力额定值。

底部止动坐落接头的设计仅适用于底部止动流量控制装置，其带有与阀座短节相同的字母名称，无论是CS-AR型还是CS-HR型，这取决于所需的压力额定值。

在完成施工设计阶段，应仔细考虑坐落接头的位置和数量，以便在各种流量控制的定位中实现最大的通用性。

◎ 坐放测试工具，如压力温度计等。

CS-AF/CS-AR LANDING NIPPLE

INTRODUCTION

Top and bottom stop landing nipple provide the location of flow control devices in the production string. Stop shoulder on seated joint to help locate and lock flow control Device. After the operation is completed, it can be picked up and recovered directly.

The design of the top stop landing nipple is only applicable to the top stop type flow control device, which has the same letter name as the valve seat subsection, whether it is CS-AF type, CS-HF type, or extreme type, depending on Required pressure rating.

The design of the bottom stop landing nipple is only applicable to the bottom stop flow control device, which bears the same letter name as the valve seat subsection, whether it is CS-AR or CS-HR, depending on the required pressure rating value.

At the completion of the construction design phase, careful consideration should be given to the location and number of joints located in order to achieve maximum versatility in various flow control positioning.

FEATURES

◎ Sealing function, the polished seal can form an effective seal with the seal;

◎ Full locking groove;

◎ The out diameter is the same as the outer diameter of the tubing coupling, and the same material;

◎ Simple structure;

◎ API standard thread.

APPLICATION

◎ Used for blind placement, for shut-in or tubing testing;

◎ For seated speed type safety valve, balance check valve, bypass circulation valve;

◎ Sitting test tools, such as pressure thermometers, etc.

Note: Other specification products are available.
