Abstract
The utility model relates to a tungsten plated alloy coupler which comprises a coupler body, wherein a tungsten alloy coating layer which is a ferronickel tungsten alloy coating layer or a nickel tungsten phosphorous alloy coating layer is plated on the surface of the coupler body. The tungsten alloy coating layer belongs to nanocrystalline or amorphous and has good corrosion resistance upon sulfurated hydrogen, carbon dioxide and mineral water as well as high temperature resistance. The utility model solves the problems of eccentric wearing and easy corrosion of an oil rod coupler in use and the corrosion and thread gluing of an oil pipe coupler, therefore, the service life of the oil rod coupler or the oil pipe coupler is greatly enhanced.
Description
Technical field
The utility model relates to a kind of box cupling, particularly a kind of box cupling of surface plating tungsten alloy.
Background technology
At present, the box cupling that is used to connect sucker rod is in use owing to work under bad environment, and the salinity height contains multiple corrosive medium, corrosion failure and eccentric wear failure phenomenon in use usually occur.In order to alleviate box cupling eccentric wear, corrosion-prone problem in use, usually carry out phosphatization and handle on the rod collar surface, but because working environment contains multiple corrosive medium, and the salinity height, unsatisfactory through the box cupling result of use of phosphatization.Equally, the box cupling that is used to connect petroleum pipeline in use usually produces the phenomenon of thread gluing between corrosion and petroleum pipeline and the petroleum pipeline box cupling owing to the reason of working environment, for corrosion and the thread gluing problem of alleviating the petroleum pipeline box cupling, usually on the screw thread of petroleum pipeline and petroleum pipeline box cupling, be coated with cup grease, anti-thread gluing agent, perhaps fill up sealing ring etc., but poor effect.
The utility model content
The purpose of this utility model provides a kind of box cupling that good corrosion-resistant, high temperature and frictional behaviour are arranged.
For achieving the above object, the utility model adopts following scheme: a kind of plating tungsten alloy box cupling, comprise the box cupling body, and the inside and outside surface of box cupling body that is used to connect the box cupling of sucker rod all is coated with one deck ferronickel tungsten alloy coating or ni-w-p alloy coating.
Be used to connect the inner surface plating one deck ferronickel tungsten alloy coating or the ni-w-p alloy coating of the box cupling of petroleum pipeline.
Also can plate one deck iron-nickel alloy coating between described box cupling body and the tungsten alloy coating as bottoming.
The hardness of described tungsten alloy coating is 800-1100Hv.
Advantage of the present utility model is: tungsten alloy coating belongs to nanocrystalline or amorphous, after Overheating Treatment, coating hardness can reach 800-1100Hv, and multiple components corrosive medium, gases such as CO2, H2S, corrosion resistance and good under the environment such as high temperature, high salinity are being arranged.Owing to improved corrosion-resistant, the scratch-resistant performance of beam hanger box cupling simultaneously, successful solution beam hanger box cupling eccentric wear, perishable phenomenon in use, with the problem of the corrosion and the thread gluing of tubing coupling, improved the application life of rod collar, tubing coupling.With the tubing coupling is example, and the tubing coupling of handling through general technology is on sequential machine is tight, shackle the thread gluing phenomenon just occurs four times easily.And through the tungsten alloy plating surface-treated tubing coupling to suppress five seconds under 46mpa air tight, sequential machine is tightly gone up, 24 inferior thread gluing phenomenons that do not occur of shackle.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 2, the described plating tungsten alloy box cupling that is used to connect sucker rod comprises box cupling body 1, and the inside and outside surface of box cupling body that is used to connect the box cupling of sucker rod all is coated with one deck ferronickel tungsten alloy coating 2 (or ni-w-p alloy coating).
The utility model can prepare according to following technology mode: pre-oil removing-washing-pre-rust cleaning-washing-electrochemical degreasing-hot water wash-washing-electrochemical activation-washing-tungsten alloy plating-washing-washing-washing.Pre-oil removing and pre-rust cleaning are in order to remove most of greasy dirt, the rusty stain of surface of the work, and electrochemical degreasing is 60-90 ℃ in temperature, contains the NaOH of 30-70g/L, the Na of 30-70g/L
3PO
4, the Na of 30-50g/L
2CO
3, the Na of 10-30g/L
2SiO
3The electric current of logical 5-10A/dm2 in the solution cleans 7-10 minute further thoroughly to remove residual greasy dirt, improves the adhesion of coating and beam hanger box cupling and tubing coupling; Hot water wash after the oil removing and washing are in order to wash the degreasing fluid of surface of the work off.Electrochemical activation adopts the sodium nitrate activating process, so that surface of the work exposes fresh matrix, improves the adhesion of workpiece and tungsten alloy coating; Washing after the activation is in order to wash the activating solution of surface of the work off; Beam hanger box cupling and tubing coupling electroplating surface tungsten alloy can greatly improve its corrosion-resistant, scratch-resistant performance, increase the service life; It is in order to take the plating bath wash clean out of on the workpiece that twice pure water after the plating washed, and hot water wash prevents the workpiece variable color.
As shown in Figure 3, the box cupling body 1 inside and outside surface that is used to connect the plating tungsten alloy box cupling of sucker rod all plates one deck iron-nickel alloy coating 3 in advance and does bottoming and use.Plated with nickel ferrotungsten coating 2 (or ni-w-p alloy coating) on iron-nickel alloy coating 3 then.
As shown in Figure 5, the inner surface of box cupling body 4 that is used to connect the plating tungsten alloy box cupling of petroleum pipeline is coated with one deck ni-w-p alloy coating 5 (or ferronickel tungsten alloy coating).
As shown in Figure 6, box cupling body 4 surfaces externally and internallies that are used to connect the plating tungsten alloy box cupling of petroleum pipeline plate one deck iron-nickel alloy coating 3 in advance and do bottoming and use.Plated with nickel tungsten phosphor alloy coating 5 (or ferronickel tungsten alloy coating) on iron-nickel alloy coating 3 then.
