Introduction of Wireline Heavy Duty Swivel Joint

A heavy duty swivel joint is used to minimize the line twist when running in and an pulling out of the well. It is usually located below rope socket and the bearings permits rotational movement when maintaining longitudinal rigidity in the tool string. This design is suitable to handle impact from heavier upwards and downward jarring.

Structure characteristics of Wireline Heavy Duty Swivel Joint

The heavy duty swivel joint consists of upper sub, lower sub, mandrel, bearing sleeve, thrust ball bearing, etc.. The mandrel with thrust ball bearing fixed is then installed to the bearing sleeve. The upper sub is connected to the bearing sleeve and the lower sub is connected to the mandrel with screws. And fix the heavy duty swivel joint between the rope socket and stem. The thrust ball bearing is with tiny friction. When the stem, etc. drives the mandrel to rotate, the upper bearing sleeve and the upper sub do not move. Thus, the wireline connected to the rope socket will be prevented from twisting off.

When jarring upward, the top end of the mandrel contacts with the upper sub. When jarring downwards, the thrust ball bearing performs reliable property even if the impact load is heavy.

If the thrust ball bearing is replaced with plane bearing, it can be applied to the operation with heavier impact load.
