I. Overview:
The ball joint is used in the tool string to connect the upper and
lower ends of the tool, and at the same time it can play a role of
righting. When going down the well, when the pipe diameter is
reduced, it can be adjusted slightly according to the pipe diameter
under the action of the spring to ensure the smoothness of the tool
string Go down the well.
II. Common technical parameters:
Specification Salvage neck Connecting thread Steel ball outer
diameter
Size | Salvage neck | Connection thread | Outer diameter of steel ball |
Φ36 | 1.375" | 15/16-10UN | Φ45.4 |
1-11/16" | 1.375" | 15/16-10UN | Φ50 |
Note: Special specifications can be provided according to customer requirements
III. Structural features and use:
The characteristic of the ball joint is the combination and change
of the buckle joint and the characteristic of the centralizer. At
the same time, the outer diameter of the steel ball can be changed
correspondingly according to the use. Compared with the
centralizer, the structure is simpler, and the operation
convenience is better.
IV, matters needing attention:
1. Before use, check whether the steel ball rotates and shrinks
flexibly without jamming.
