一种新型套管头试压装置设计

Design of A New Type of Casing Head Pressure Test Device

现有的套管头试压装置是通过钢制螺纹连接并密封的,会造成套管头本体螺纹拉伤、拉毛等现象发生,直接影响了套管头的质量,严重时会造成螺纹粘扣,直接导致套管头本体和试压堵头的报废。为了避免上述情况的出现,设计了一种新型的套管头试压装置,将套管头置于两块用螺栓连接的顶板和底板之间进行试压,保护了本体螺纹,保证了管接头的质量,同时提高了试压效率和安全保障。

The existing casing head pressure test device is connected and sealed by steel thread, which will cause the threading of the casing head body, such as thread tension, nap and so on, which directly affects the quality of the casing head and will cause the thread Gluing, a direct result of the casing head and the pressure test plug of the scrapped.In order to avoid the above situation, the design of a new type of casing head pressure test device, the casing head placed in two bolts connected between the roof and the floor between the pressure test to protect the body thread to ensure that the pipe joints Of the quality, while improving the pressure test efficiency and security.
