Abstract
The utility model discloses a kind of compound conveying high-pressure oil pipe, comprise three-decker, outermost surface is high strength carbon steel layer, pipeline entirety and inwall thereof are played a supporting role, described internal layer adopts high chromium cast iron layer, described rich chromium cast iron has and well prevents corrosion ability, described mesosphere is packing layer, described packing layer adopts fluoroplastic composition, mixed by soluble poly tetrafluoroethylene and polyparaphenylene phenol and form, the beneficial effects of the utility model are: employ three-decker, avoid the harm that inner wall abrasion causes, improve Security, operational safety is high, anticorrosive, shock resistance.
Description
Technical field
The present invention relates to high pressure pipe line field, particularly relate to a kind of compound conveying high-pressure oil pipe.
Background technique
Pipeline is in transfer oil, and rock gas, chemical product have extensive use, long distance delivery, and general inner-walls of duct bears larger pressure, severe along with transportation environment, and pipeline is likely frayed, causes pipeline leakage, the serious accident consequence of cracking.
Existing multiple tube is generally two-layer compound, skin is base tube, skin bears supporting steel pipe effect, and internal layer is composite pipe, is made up of corrosion-resistant material, internal layer directly contacts with the material of conveying, because internal layer is thin-walled layer, use for a long time, due to the impact of material, internal layer inwall can be made to come off, shorten the working life of pipeline.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of compound conveying high-pressure oil pipe, can strengthen composite oil pipe working life, ensures use safety.
Described a kind of compound conveying high-pressure oil pipe comprises three-decker, and outermost surface is carbon steel layer, and to pipeline, overall and inwall is played a supporting role, and in order to increase pipeline working life, described pipeline outer wall is provided with projection.
Described internal layer adopts chromium cast iron contained layer, and described rich chromium cast iron has and well prevents corrosion ability, meanwhile, has very high intensity.
Described mesosphere is packing layer, and described packing layer adopts fluoroplastic composition, is mixed form by soluble poly tetrafluoroethylene and polyparaphenylene phenol.Described soluble poly tetrafluoroethylene is the fluoroplastic of newer melt-processable, and be called for short PFA, fusing point is high, and density is 2.13 grams/cc to 2.16 grams/cc, and PFA is heat-resisting, cold-resistant, chemical stability.
PPL, polyparaphenylene phenol is wear-resisting, sealing material ideal in the industries such as metallurgy, chemical industry, high life, high temperature resistant, meanwhile, polyparaphenylene good thermal stability, corrosion resistance, self-lubricating property is better than molybdenum disulfide and graphite, the molecular chain of PPL, due to very large rigidity and regularity, makes it cannot not be molten insoluble, self machine shaping difficulty, need fill the blended use of other materials.
Mesosphere adopts PFA and PPL blended, and intermediate layer thickness is between 5 millimeters to 10 millimeters.
The invention has the beneficial effects as follows: present invention uses three-decker, avoid the harm that inner wall abrasion causes, improve Security, operational safety is high, anticorrosive, shock resistance.
Accompanying drawing explanation
Fig. 1 is a kind of compound conveying high-pressure of the present invention vitta structure schematic diagram.
In accompanying drawing, the mark of each parts is as follows:
1 is that high-pressure oil pipe is outer, and 2 is high-pressure oil pipe internal layer, and 3 is high-pressure oil pipe mesosphere, and 4 is outer projection.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of compound conveying high-pressure oil pipe comprises three-decker, and outermost surface is carbon steel layer, and to pipeline, overall and inwall is played a supporting role, and in order to increase pipeline working life, described pipeline outer wall is provided with projection.
Described internal layer adopts chromium cast iron contained layer, and described rich chromium cast iron has and well prevents corrosion ability, meanwhile, has very high intensity.
Described mesosphere is packing layer, and described packing layer adopts fluoroplastic composition, and mixed by soluble poly tetrafluoroethylene and polyparaphenylene phenol and form, mesosphere adopts PFA and PPL blended, and interior thickness is between 5 millimeters to 10 millimeters.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
