Abstract
The utility model discloses a nickel-based alloy hose, and belongs to the technical field of pipelines for fluid conveying. The nickel-based alloy hose comprises a nickel-based alloy hose body and joints located at the two ends of the nickel-based alloy base body, transitional joints are arranged between the nickel-based alloy hose body and the joints, fireproof sleeves made of inflaming retarding and thermal insulation materials are arranged on the outer portions of the joints and the outer portions of the transitional joints in a wrapping mode, a flexible abrasion-resistant part is arranged in the nickel-based alloy hose body, and an inflaming retarding layer made of inflaming retarding and thermal insulation materials is arranged on the outer surface of the nickel-based alloy hose body. The nickel-based alloy hose has the advantages of being reasonable in structure, long in service life and capable of reducing the use cost and the maintenance cost.
Description
Technical field
The utility model relates to a kind of nickel-base alloy flexible pipe, belongs to tube for fluid transfer road technique field.
Background technique
Along with socioeconomic development, the demand of fluid delivery pipeline is more and more, also more and more higher to the requirement of delivery line.At the coal injection system of some ironmaking, make steel concise stove or other and dredge the occasion of solid material, with common metal flexible pipe, will soon be worn, and rate of flow of fluid is higher, wearing and tearing are just more serious, have a strong impact on working life, increase user cost.In addition; these places are because the temperature of surrounding environment is very high; also have metallic solution or slag splashes; also can cause the rapid aging of delivery line and damage; the protected-type of traditional flame resistant heat insulation materials such as looping asbestos cloth outside pipeline, still can affect because of the damage of asbestos cloth its working life.Therefore, should provide a kind of new technological scheme to address the above problem.
Summary of the invention
The purpose of this utility model is: for above-mentioned deficiency, provide a kind of rational in infrastructure, using effect good, serviceability is strong a kind of nickel-base alloy flexible pipe.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of nickel-base alloy flexible pipe, comprise nickel-base alloy flexible pipe body and the joint that is positioned at its two ends, between nickel-base alloy flexible pipe body and joint, be provided with transit joint, the outer wrap of described joint and transit joint has by flame resistant heat insulation material makes fire-proof covering, the inside of described nickel-base alloy flexible pipe body is provided with flexible wear part, and the outer surface of described nickel-base alloy flexible pipe body is provided with the flame-retardant layer of being made by flame resistant heat insulation material.
The related content of technique scheme is explained as follows:
In technique scheme, between described flame-retardant layer and nickel-base alloy flexible pipe body, be also provided with vacuum layer.
In technique scheme, described flexible wear part is close around forming by spring steel steel wire.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1, because the utility model has in the outer wrap of joint and transit joint the fire-proof covering of being made by flame resistant heat insulation material; outer surface at nickel-base alloy flexible pipe body is provided with the flame-retardant layer of being made by flame resistant heat insulation material; it can protect nickel-base alloy flexible pipe body not to be damaged, and extends its working life.
2,, because the utility model is also provided with vacuum layer between flame-retardant layer and nickel-base alloy flexible pipe body, it can reduce intraluminal fluid state fluid and extraneous efficiency of carrying out heat exchange greatly, reduces unnecessary waste, also can avoid cryogenic piping to cause frostbite.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model embodiment one structural representation.
In above accompanying drawing: 1, nickel-base alloy flexible pipe body, 2, joint, 3, transit joint, 4, fire-proof covering, 5, flexible wear part, 6, flame-retardant layer; 7, vacuum layer.
