Abstract
The invention discloses a compound metallic hose, which comprises a sealing ring, a movable sleeve flange, a connecting pipe, a stainless steel corrugated pipe and a fixed flange, wherein the stainless steel corrugated pipe is welded to the connecting pipe through a protection sleeve; a layer of nitrile rubber is vulcanized on the outer surface of the stainless steel corrugated pipe; a layer of steel wire net sleeve is sleeved on the stainless steel corrugated pipe; and one end of the connecting pipe is welded with the sealing ring, and the other end of the connecting pipe is welded with the fixed flange. By the compound metallic hose, a product has a dual-layer sealing effect; furthermore, the pressure-bearing capacity is improved and the service life of the product is prolonged.
Description
Technical field
The present invention relates to a kind of flexible pipe, particularly a kind of composition metal flexible pipe.
Background technique
Metallic composite; Be meant the composite material that utilizes complex technique or multiple, chemical, mechanical property different metallic on the interface, to realize metallurgy combination and form; It greatly improves many performances such as thermal expansivity, intensity, fracture toughness, impact toughness, wearability, electrical property, magnetic property of single metal material, thereby is widely applied to industrial fields such as product is widely used in oil, chemical industry, boats and ships, metallurgy, mine, machine-building, electric power, water conservancy, traffic, environmental protection, pressurized container manufacturing, food, brewages, pharmacy.The mode of production of domestic and international compound composite material mainly contains combined techniques between solid-liquid phase combined techniques, solid phase, lamination hot rolling method, diffusion crimping method, welding method, built-up welding hot rolling method etc.Combined techniques is explosive welding and hot rolling between modal solid phase.1, the development and application at home and abroad of the method for explosive welding Stainless Compound Steel Plate all starts to walk a little later.The exploitation sixties, the seventies is full-fledged, and entering is commercially produced.2, the method for rolling Stainless Clad Steel Clad Steel Plate has just caused some researchers' concern as far back as the thirties in 20th century, and rolling compound to be divided into hot rolling compound and cold rolling compound.This composite algorithm output is high, and dimensional accuracy is high, and technology and equipment are comparatively ripe, but often will carry out surface treatment and annealing enhancement process.
Metallic hose is generally used between pipeline and the pipeline, being flexible coupling between pipeline and the equipment, and the traditional metal flexible pipe is not generally taked encryption measures, causes sealability bad.
Summary of the invention
The object of the present invention is to provide a kind of composition metal flexible pipe, make product have the effect of double-layer seal, and strengthened bearing capacity, improved the working life of product.
Technological scheme of the present invention is: a kind of composition metal flexible pipe; Said composition metal flexible pipe comprises seal ring, lap joint flange, adapter, corrugated stainless steel tubing and fastening flange; Said corrugated stainless steel tubing is welded in the adapter through protecting jacket, and the table sulfuration of said corrugated stainless steel tubing outside has one deck nitrile butadiene rubber.
In preferred embodiment of the present invention, also be with the layer of steel wire net on the said corrugated stainless steel tubing.
In preferred embodiment of the present invention, said adapter one end and seal ring welding, the other end and fastening flange welding.
In preferred embodiment of the present invention, said nitrile butadiene rubber is made up of butadiene and acrylonitrile.
A kind of composition metal flexible pipe of the present invention makes product have the effect of double-layer seal, and has strengthened bearing capacity, has improved the working life of product.
Description of drawings
Accompanying drawing 1 is the perspective view of composition metal flexible pipe one preferred embodiment of the present invention.
The mark of each parts is following in the accompanying drawing: 1, metal tape, 2, plastic film layers, 3, the water uptake expansion resin layer.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1; Fig. 1 is a kind of composition metal flexible pipe of the present invention; Said composition metal flexible pipe comprises seal ring 1, lap joint flange 2, adapter 3, corrugated stainless steel tubing 4 and fastening flange 5; Said corrugated stainless steel tubing is welded on through protecting jacket and takes on 3, and the table sulfuration of said corrugated stainless steel tubing outside has one deck nitrile butadiene rubber.
In one embodiment; A kind of composition metal flexible pipe of the present invention; Said composition metal flexible pipe comprises seal ring, lap joint flange, adapter, corrugated stainless steel tubing and fastening flange, and said corrugated stainless steel tubing is welded in the adapter through protecting jacket, and the table sulfuration of said corrugated stainless steel tubing outside has one deck nitrile butadiene rubber; Also be with the layer of steel wire net on the said corrugated stainless steel tubing; Said adapter one end and seal ring welding, the other end and fastening flange welding, said nitrile butadiene rubber is made up of butadiene and acrylonitrile.
Further specify, when said composition metal flexible pipe being used for large-scale external floating roof tank central authorities drainage means and connecting, for making outside the smooth drain tank of ponding on the floating top; Need to connect as bypass with said composition metal flexible pipe, guarantee that two steel pipe intercommunications up and down do not influence the rotation of hinge again in the joint of two steel pipes, equally at hinge place up and down also with a said composition metal flexible pipe transition floating top drain opening and a jar end drain interface; Reach the purpose of draining,, thereby overcome sealing problem because of corrugated stainless steel tubing makes said composition metal flexible pipe have the double-sealing effect; Guaranteed the reliability of central drainage means,, do not had the trapped fuel phenomenon simultaneously because of surface smoothing behind the vulcanized rubber at movement process; After the outer surface sulfuration of corrugated stainless steel tubing has nitrile butadiene rubber,, just can strengthen the intensity of metallic hose at braiding layer of metal net; Improve the working life of product; Said in addition composition metal flexible pipe two ends adopt lap joint flange to be connected with fastening flange, can under the situation of not getting angry, dismantle, and are easy to maintenance.A kind of composition metal flexible pipe of the present invention makes product have the effect of double-layer seal, and has strengthened bearing capacity, has improved the working life of product.
Embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed, and variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
