Abstract
A glass fiber reinforced plastic (FRP) composite interface structure for an oil field comprises an inner liner pipe and an outer pipe outside the inner liner pipe and is characterized in that the inner liner pipe at the pipe head is longer than the outer pipe, the portion extending out of the inner liner pipe turns outwards to wrap up the external surface of the outer pipe, and a rubber gasket is arranged on the outward turning inner liner pipe. FRP composite pipe interfaces are screwed and connected through a metallic interface sleeve, and a rubber gasket is arranged at the joint of the interfaces. A sealant layer is arranged between the outer wall of the rubber gasket of the FRP composite pipe interface and the inner wall of the metallic interface sleeve for bonding. The interface structure effectively prevents the problems caused by high temperature erosion of FRP section, and is solid, anti-compression and hermetic.
Description
Technical field
The utility model is specifically related to a kind of oil field composite glass steel pipe interface structure.
Background technique
The oil field is for delivery of the existing corrosion-resistant of metal tube of oil, water and the inorganic salts mixing material of high temperature, the defective that lack working life at present, and the jointing of transport pipe is the weak link of tubing, and common interface method is that shimming connected with the threaded Steel Sleeve of internal diameter after the mouth of pipe was polished flat.Because tubing is for delivery of oil, water and the inorganic salts mixed pressure liquid of High Temperature High Pressure, along with the use of tubing, the glass fibre reinforced plastics section of jointing can be owing to the erosion of high-temp liquid, and performance is deterioration slowly, causes that then tubing lost efficacy, interface ruptures or explosion.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of high performance oil field composite glass steel pipe interface structure, the tubing of this structure is that general thermoplastic macromolecule material is carried out high performance, its heat-resisting quantity, solvent resistance and mechanical property are promoted significantly, effectively avoided the glass fibre reinforced plastics section to suffer high-temp liquid to corrode the serial problem that causes.The connection of this structure has also added the sealer sealing except the rubber sheet gasket that uses special substance.
To achieve these goals, the technical solution adopted in the utility model is: a kind of oil field composite glass steel pipe interface structure, include internal lining pipe, internal lining pipe is provided with outer tube outward, it is characterized in that, internal lining pipe is longer than outer tube at the tube head place, and the part that internal lining pipe grows is turned up and is coated on the outer surface of outer tube, and the internal lining pipe that coats that turns up is provided with a rubber washer.
Best, described internal lining pipe adopts acrylic resin.
Best, described outer tube adopts the thermosetting resin based composites.
Further technological means is, connect by metal interface sleeve pipe spiral shell solid phase between the described composite glass steel pipe interface, and the interface joint is provided with rubber sheet gasket.
Best, arrange between the outer wall of described composite glass steel pipe interface rubber washer and the inwall of metal interface sleeve pipe that sealant layer is gluing to be connect.
Best, described rubber sheet gasket adopts acrylate rubber.
The beneficial effects of the utility model are:
1, because the utility model carries out high performance with general thermoplastic macromolecule material, its heat-resisting quantity, solvent resistance and mechanical property are promoted significantly, poor, the easy swelling of environmental stress resistance of pipe existence in original common plastics, the defective that serviceability temperature is low, working life is short have been solved, improved working pressure, working life and the bursting pressure of composite pipe greatly, can be for a long time for delivery of temperature up to more than 110 ℃, pressure is greater than oil, water and the inorganic salts mixed pressure liquid of 2.5 MPas.This multiple tube is formability and the solvent resistance of thermoplastic composite material, organically combines with high-strength, the high mould of thermosetting plastics, gives the resistance to pressure under solvent resistance, heat-resisting quantity and the high temperature of product excellence.Not only can replace the metal tube that present oil field is used fully, and overcome the defective of lacking in the corrosion-resistant that metal tube exists, working life, the life-span can reach 30-50 (be 2-3 the working life of metal tube).
2, the utility model adopts thermoforming processing, with jointing glass fibre reinforced plastics section with the internal lining pipe coating of turning up, with clad thermoforming processing, typing, finishing, make it firmly to combine closely on frp layer again, effectively avoided the glass fibre reinforced plastics section to suffer high-temp liquid to corrode the serial problem that causes.
3, two tubing mouths of the utility model, add a kind of special oil resistant, high temperature resistant aging high-strength rubber pad, after the butt joint, with tapped steel interface sleeve pipe closely connect, fastening, with the sealing of special sealer, efficiently solve firmly, problems such as resistance to compression and sealing between interface internal surface of sleeve pipe and outer pipe wall.
Description of drawings
Fig. 1 is pipeline sectional structure schematic representation of the present utility model.
Fig. 2 is pipe connecting structure cross-sectional schematic of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Referring to accompanying drawing 1, a kind of composite glass steel pipe interface, include the internal lining pipe 1 of acrylic resin, the internal lining pipe 1 outer glass fibre reinforced plastics outer tube 2 that is provided with the thermosetting resin base composite material, be longer than outer tube 2 at tube head place internal lining pipe 1, the part that internal lining pipe 1 grows is turned up and is coated on outer tube 2, and the internal lining pipe 1 that is coated on the outer tube 2 that turns up is provided with a rubber washer 3.As Fig. 2 and 3, connect by metal interface sleeve pipe 4 spiral shell solid phases between the composite glass steel pipe interface, and the interface joint is provided with the rubber sheet gasket 5 of acrylate, and sealant layer 6 gluing connecing are set between the outer wall of composite glass steel pipe interface rubber washer and the inwall of metal interface sleeve pipe.
The design is dipped in jointing glass fibre reinforced plastics section in the 180-200 ℃ of oil bath earlier and makes it softening, take out subsequently and carry out thermoforming processing, typing, finishing immediately, make it firmly to combine closely on frp layer, it should be noted that, oily temperature during thermoforming remains on and can make polypropylene softening, and the shaping operation of turning up that is beneficial to internal lining pipe gets final product.The back also is provided with rubber ring for the ease of connection metal interface cover and makes it closely firm because internal lining pipe turns up, but pipeline can increase and the not pipeline of flange because having added rubber ring, therefore also will be to the pipe joint finishing of polishing, the pipe outer wall after internal lining pipe is turned up is realized smoothly.When handling two tubing mouths continuous, add a kind of special oil resistant, high temperature resistant aging high-strength rubber pad, acrylate rubber pad just, after the butt joint, with tapped steel interface sleeve pipe closely connect, fastening, between interface internal surface of sleeve pipe and outer pipe wall with the sealing of special sealer.
Interface structure design method of the present utility model, the serial problem of both effectively having avoided the glass fibre reinforced plastics section corroded by high-temp liquid causing, again firmly, resistance to compression, sealing.
