Abstract
The utility model discloses a wholly-formed ceramic elbow, comprising an elbow body, wherein the elbow body is a steel straight pipe and is formed through hot bending by adopting an intermediate-frequency hot-bending manner; simultaneously, the two ends of the elbow body are also provided with joint flanges which are butted with a straight pipe part of the elbow body, so that the bearing of the pipeline for the designing pressure and the working pressure can be ensured; and simultaneously, the wholly-formed ceramic elbow is lined in the elbow body. The wholly-formed ceramic elbow disclosed by the utility model has the advantages that the process is simple, the processing is convenient, the assembly is easy and the wear resistance of an oil-gas pipeline can be effectively improved.
Description
Technical field
The utility model relates to the oil gas field tube bends, is specially a kind of bulk ceramics bend pipe that is equipped with.
Background technique
Generally speaking, the exploitation of oil-gas field rock gas must use the pipeline transport gas, because the requirement of working environment and landform, just must be combined into the pipeline conveyor line by various bend pipes, straight tube, and rock gas there are various impurity to mix in gatherer process, as: sand, quartz, dolomite, Shi Yan, clay, calcite etc., enter pipeline with rock gas, under the effect of working pressure, cause great wearing and tearing to pipeline.At present, oil gas field uses the common pipe transport gas, and under the effect of impurity, the pipeline life cycle shortens, and bend pipe impaired in pipeline be the most serious.Elbow is impaired will to leak air, and is unallowed in working environment and leak rock gas, brings great hidden danger to safety in production.Changing pipeline also for simultaneously the shutdown maintenance makes troubles.
The model utility content
The technical problem that the utility model solves is to provide a kind of global formation ceramic elbow, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of global formation ceramic elbow, comprise the bend pipe body, described bend pipe body is the mode hot bending that steel straight tube adopts the intermediate frequency hot bending, simultaneously, also be provided with flange at the two ends of bend pipe body and dock the design pressure that guarantees to be in the charge of and working pressure with the straight-tube portion of bend pipe body.Simultaneously, be lined with the ceramic elbow of global formation in the bend pipe body.
In the utility model, the ceramic elbow material adopts 95 aluminium oxide ceramics, density reaches 3.6, Rockwell hardness 〉=85HRA, compressive strength 〉=850Mpa uses ceramic-linedly, can make bend pipe inner surface of tube body degree of finish and hardness higher, be highly resistant to various Mediawears, Effective Raise prolongs the working life of pipeline.
In the utility model, adopt high temperature resistant mighty bond bonding between the ceramic elbow in the described global formation ceramic elbow and the bend pipe body, ceramic elbow sticks on elbow interior wall.Simultaneously, closely be connected between ceramic elbow and the elbow interior wall, seamless, in order to meet design requirement.
Beneficial effect: the utility model is simple in structure, effectively reduces impurity to the wearing and tearing of pipeline, has improved the working life of pipeline, changes number of times thereby reduce, and has improved the coefficient of safety in production.Guarantee the stability of producing, thereby improved economic benefit.

Fig. 1 is the utility model mounting structure schematic diagram.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Preferred embodiment referring to a kind of global formation ceramic elbow of Fig. 1, in the present embodiment, comprise bend pipe body 1, described bend pipe body 1 adopts the mode hot bending of intermediate frequency hot bending for steel straight tube, simultaneously, also be provided with flange 3 at the two ends of bend pipe body 1 and dock the design pressure that guarantees to be in the charge of and working pressure with the straight-tube portion of bend pipe body 1.
Simultaneously, be lined with the ceramic elbow 4 of global formation in bend pipe body 1, ceramic elbow 4 adopts 95 aluminium oxide ceramics to make, its density reachable to 3.6, Rockwell hardness 〉=85HRA, compressive strength 〉=850Mpa, use ceramic elbow 4 as liner, can make bend pipe body 1 internal surface degree of finish and hardness higher, be highly resistant to various Mediawears, Effective Raise prolongs the working life of pipeline.
In the present embodiment, adopt high temperature resistant mighty bond 3 bonding between described ceramic elbow 4 and the bend pipe body 1, ceramic elbow 4 sticks on the elbow interior wall of bend pipe body 1.Simultaneously, closely be connected between ceramic elbow 4 and the elbow interior wall, seamless, in order to meet design requirement.
Above demonstration and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
