Abstract
The utility model discloses a composite metal hose comprising a sealing ring, a loose flange, an adapter tube, a stainless corrugated tube and a fixed flange, wherein the stainless corrugated tube is welded on the adapter tube through a protective sleeve and a layer of nitrile-butadiene rubber is vulcanized on the outer surface of the stainless corrugated tube; a layer of steel wire gauze sleeve is also sheathed on the stainless corrugated tube; and one end of the adapter tube is welded with the sealing ring and the other end thereof is welded with the fixed flange. The composite metal hose has the benefits of: causing the product to have the effect of double-layer sealing, enhancing pressure bearing capacity and prolonging the service life of the products.
Description
Technical field
The utility model relates to a kind of composition metal flexible pipe, and the central drainage means of particularly a kind of large-scale external floating roof tank is flexible coupling and uses the composition metal flexible pipe.
Background technique
Metallic hose is generally used between pipeline and the pipeline, being flexible coupling between pipeline and the equipment.The conventional metals flexible pipe is not generally taked encryption measures, causes sealability bad.
Summary of the invention
At the shortcoming of prior art, the utility model provides a kind of novel composition metal flexible pipe.
To achieve these goals, the measure taked of the utility model:
The composition metal flexible pipe comprises seal ring, lap joint flange, adapter, corrugated stainless steel tubing and fastening flange, and corrugated stainless steel tubing is welded in the adapter by protecting jacket, and described corrugated stainless steel tubing outer surface sulfuration has one deck nitrile butadiene rubber;
Also be with the layer of steel wire net on the described corrugated stainless steel tubing;
Described adapter one end and seal ring welding, the other end and fastening flange welding.
The beneficial effects of the utility model: make product have the effect of double-layer seal, and strengthened bearing capacity, improved the working life of product.
Description of drawings
Fig. 1, structural representation of the present utility model.
Embodiment
As shown in Figure 1, the composition metal flexible pipe, comprise seal ring 1, lap joint flange 2, adapter 3, corrugated stainless steel tubing 7 and fastening flange 8, corrugated stainless steel tubing 7 is welded on by protecting jacket 4 and takes on 3, and described corrugated stainless steel tubing 7 outer surfaces sulfuration has one deck nitrile butadiene rubber 6; Also be with layer of steel wire net 5 on the described corrugated stainless steel tubing 7; Described adapter 3 one ends and seal ring 1 welding, the other end and fastening flange 8 welding.
When described composition metal flexible pipe being used for large-scale external floating roof tank central authorities drainage means and being flexible coupling, for making outside the smooth drain tank of ponding on the floating top, need to connect as bypass with described 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, reach the purpose of draining at hinge place up and down also with a described composition metal flexible pipe transition floating top drain opening and a jar end drain interface.Because of corrugated stainless steel tubing 7, make described composition metal flexible pipe have the double-sealing effect, thereby overcome the motive sealing problem, guaranteed the reliability of central drainage means at movement process, simultaneously level and smooth because of having vulcanized the rubber rear surface, there is not the trapped fuel phenomenon; After the outer surface sulfuration of corrugated stainless steel tubing 7 has nitrile butadiene rubber 6, weave layer of metal net 5 again, just can strengthen the intensity of metallic hose, improve the working life of product.In addition, described composition metal flexible pipe two ends adopt lap joint flange 2 to be connected with fastening flange 8, can dismantle under the situation of not getting angry, and are easy to maintenance.
The utility model can also be that-10 °～90 °, working pressure are to use among the 1.6Mpa in medium, operating temperatures such as crude oil and other fuel oil, and can reach 10 years working life.
