Abstract
The utility model discloses a boats and ships or ocean engineering non ferrous metal pipe crossing cabin double cannula structure, including non ferrous metal pipeline (1) of passing hull bulkhead or deck (3), work in unison from inside to outside and cup joint inlayer sleeve pipe (4) unanimous with non ferrous metal pipeline material in proper order in non ferrous metal pipeline outside, and with outer sleeve pipe (5) that bulkhead or deck (3) material is unanimous, outer sleeve pipe welded fastening passes through the hole in bulkhead or deck. The utility model discloses boats and ships or the design of ocean engineering non ferrous metal pipe crossing cabin double cannula for such as non ferrous metal pipeline crossing cabins such as stainless steel or corronil or titanium alloys. This kind of sleeve pipe is formed by inlayer sleeve pipe and outer sleeve pipe coupling, and inlayer sleeve pipe material is the same with the pipeline material, outer sleeve pipe is equal with bulkhead or deck, has avoided non ferrous metal pipeline and steel bulkhead or deck because of the electrochemical corrosion of not idiostatic intermetallic contact production well, has lengthened pipeline life, has guaranteed the normal operating of system.
Description
Technical field
The present invention relates to the design of metal tube crossing cabin in boats and ships or ocean engineering, more particularly, relate to the architecture advances of crossing cabin metal tube.
Background technique
As shown in Figure 1, non-ferrous metal pipe 1 crossing cabin uses the steel being equal to material with bulkhead or deck 3 to lead to shipping bill sleeve pipe 2 usually, namely Steel Casing 2 and non-ferrous metal pipe directly contact and weld, owing to there is potential difference between two kinds of different metals, add that pipeline working environment is comparatively severe, easily in the region A shown in Fig. 1, electrochemical corrosion occurs.
More case is had to confirm, the normal operation of corrosive pipeline not only entail dangers to pipe-line system, but also can because keeping in repair the waste of material and the manpower brought, more severe case even jeopardizes the safety of boats and ships or ocean platform, and problems also more and more causes the great attention of each side concerned.
Summary of the invention
For the problems referred to above, the invention provides that a kind of corrosion resistance is strong, the crossing cabin non-ferrous metal pipe structure of long service life.
In order to achieve the above object, the invention provides a kind of boats and ships or ocean engineering nonferrous metal tube crossing cabin double-tube structure, comprise the non-ferrous metal pipe through hull bulkhead or deck, the outside inner layer sleeve that socket is consistent with described non-ferrous metal pipe material successively with one heart from inside to outside of described non-ferrous metal pipe, and the outer layer sleeve consistent with described bulkhead or deck material; Described outer layer sleeve is fixedly welded on passing through in hole of described bulkhead or deck.
Boats and ships of the present invention or the design of ocean engineering nonferrous metal tube crossing cabin double-jacket tube, for such as stainless steel or the non-ferrous metal pipe such as corronil or titanium alloy crossing cabin.This kind of sleeve pipe is coupled to form by inner layer sleeve and outer layer sleeve, inner layer sleeve material is identical with pipe material, outer layer sleeve is equal to bulkhead or deck, avoid the electrochemical corrosion that non-ferrous metal pipe and steel bulkhead or deck produce because of different potentials difference intermetallic contact well, extend pipeline working life, ensure that the normal operation of system.
Accompanying drawing explanation
Fig. 1 is the structural representation of nonferrous metal tube crossing cabin in prior art boats and ships or ocean engineering.
Fig. 2 is the structural representation of nonferrous metal tube crossing cabin in art boats and ships of the present invention or ocean engineering.
Embodiment
As shown in Figure 2, the present invention chooses the inner layer sleeve 4 of material identical with non-ferrous metal pipe 1, is enclosed within the nonferrous metal tube position chosen in advance, outside and welds.Choose the equivalent outer layer sleeve 5 of material according to hull bulkhead or deck 3 armor plate strength used, and be welded on inner layer sleeve 4.Therefore the present invention passes through pipe and is coupled to form by inner layer sleeve 4 and outer layer sleeve 5, inner layer sleeve 4, and material is identical with pipe material, and outer layer sleeve is equal to bulkhead or deck, and inner layer sleeve is used as to sacrifice sleeve pipe.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technological scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
Claims (1)
1. boats and ships or ocean engineering nonferrous metal tube crossing cabin double-tube structure, comprise the non-ferrous metal pipe (1) through hull bulkhead or deck (3), it is characterized in that, described non-ferrous metal pipe (1) the outside inner layer sleeve (4) that socket is consistent with described non-ferrous metal pipe (1) material successively with one heart from inside to outside, and the outer layer sleeve (5) consistent with described bulkhead or deck (3) material;
Described outer layer sleeve (5) is fixedly welded on passing through in hole of described bulkhead or deck (3).
