High Quality Rotary wellhead for Oil Well

1. Application

It is used for oil well with serious eccentric wear. By rotating tube to reducing the friction between tube and sucker rod, so as to prolong tube service life andpump inspection cycle.

2. Structure and Work principle:

It’s a kind of device with many advantages, such as simple structure, low cost, convenient operation, and good effect and so on.

It is mainly composed of upper joint, “O” ring, connecting bolt, rotating body, tubing hanger and bearings.

When use it, discharge the lower flange and installed on the casing directly. Insert 25mm(19mm)sucker rod into radial of rotating body, and then rotate it by hand to realize unidirectional turn right movement. So the tube will rotate with it.
