The anti-explosion lift sub comprises a lift sub body and is characterized in that anti-corrosion layers are electroplated on the inner surface of the lift sub body and the outer surface of the lift sub body respectively, and the anti-corrosion layers are copper layers. The anti-explosion lift sub has the advantages of being simple in structure and convenient to manufacture and having quite good anti-explosion performance and quite good anti-corrosion performance.
Description
Technical field
The utility model relates to a kind of elevator, specifically, relates to a kind of explosion-proof elevator.
Background technology
Elevator is indispensable rig tool in petroleum gas brill, workover treatment process, and its function is to hold and promote the tubing strings such as drilling rod, sleeve pipe, drill collar, oil pipe.In actual applications, because there is so property gas (as hydrogen sulfide) at drilling and repairing well scene, elevator when work easily with tubing string or with other objects generation spark that collides, may cause the accidents such as burning, blast, the while is also easy to the tubing string of damaging.In addition, existing elevator surface is perishable, and the application life in the perishable environment such as ocean is short.Therefore, need a kind of new technical scheme to solve above-mentioned technical problem.
Summary of the invention
The purpose of this utility model is that a kind of elevator anticorrosion, explosion prevention function that has will be provided, and is applicable to operation in the perishable environment such as ocean.
In order to achieve the above object, the utility model adopts following technical scheme:
An explosion-proof elevator, comprises elevator housing, is all electroplate with one deck anticorrosive coat on the surfaces externally and internally of described elevator housing, and described anticorrosive coat is copper layer.
The thickness of described copper layer is 25～30um.
The utility model has the advantages that: simple in structure, easily manufactured, there is very strong explosion-proof, Corrosion Protection.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model structural representation.
Wherein: 1, elevator housing, 2, copper layer.
The specific embodiment
As shown in Figure 1, a kind of explosion-proof elevator, comprises elevator housing 1, is all electroplate with layer of copper layer 2 on the surfaces externally and internally of elevator housing, in order to reduce production costs under the prerequisite that does not affect function, the thickness of copper layer 2 is set as to 25～30um.
Claims (2)
1. an explosion-proof elevator, comprises elevator housing, it is characterized in that: on the surfaces externally and internally of described elevator housing, be all electroplate with one deck anticorrosive coat, described anticorrosive coat is copper layer.
2. a kind of explosion-proof elevator according to claim 1, is characterized in that: the thickness of described copper layer is 25～30um.
