Personnel have developed pumpingh well impressed current method anti-corrosive apparatus, to guarantee between the hanger and casing connection device of this device absolutely
The top of edge, oil pipe will be suspended on casing connection device by hanger, it is desirable that also be wanted between hanger and the top of oil pipe
Insulation, there is presently no such hangers.
Summary of the invention
The purpose of the utility model is to provide a kind of insulation oilpipe suspending devices, solve pumpingh well impressed current method anti-corrosive apparatus
Need the problem of insulating between hanger and casing connection device.
The utility model is realized in this way: including suspension body, insulation positioning ring, suspension joint, suspension body connects with suspension
It is isolated between head by insulation positioning ring, is transmitted to the electric energy on suspension joint will not on suspension body, suspension joint lower suspension
Tubing weight be transmitted on suspension body by the positioning ring that insulate, the material of the positioning ring that insulate is electrically non-conductive material.
Suspension body upper section diameter of bore is greater than lower section diameter of bore, forms shoulder, insulation positioning two sections of diameter interfaces
Ring is placed in the inner circular bead of suspension body, and outer wall and suspension body upper section the inner wall cooperation for the positioning ring that insulate position, suspension joint
Upper section outer diameter is greater than lower section outer diameter, and outer shoulder is formed at two sections of diameters, and suspension joint is inserted into suspension body, the between outer land of suspension joint
Shoulder is seated on insulation positioning ring, and the lower section outer wall of suspension joint and the inner wall of insulation positioning ring cooperate positioning, makes suspension joint
Upper section outer wall is not contacted with the upper section inner wall of suspension body, and the lower section outer wall of suspension joint is not contacted with the lower section inner wall of suspension body.
Setting prevents suspension joint Shang Cuan mechanism between the lower part and suspension joint of suspension body, makes suspension joint and suspension
It cannot be relatively moved between body.
The suspension joint Shang Cuan mechanism that prevents includes dead ring, pressing sleeve, pressure after dead ring is sleeved on suspension joint
Set is connect with suspension joint, is fixed on dead ring between the lower end surface of suspension body and the upper surface of pressing sleeve, the material of dead ring
Material is electrically non-conductive material, prevents the electric energy on suspension joint from being transmitted on suspension body.
The material of insulation positioning ring is ceramic material.
The material of dead ring is ceramic material.
Felt pad is installed on the top of suspension body, the internal diameter of felt pad is greater than the upper-end inner diameter of suspension joint, makes felt pad
Inner wall and suspension joint between form shoulder.
The beneficial effects of the utility model are: when meeting the requirement for bearing suspension tubing weight, suspension body and outstanding
Hanging joint does not contact, and the electric energy on suspension joint will not reach on suspension body, can be used for pumpingh well impressed current method anti-corrosion dress
On the wellhead assembly set.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model.
