Embodiment Construction
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0019] refer to figure 1 , a marine flanged pipe fitting, including a pipe body 1, a connecting flange 2, a casing body 3 and a casing flange 4. Both ends of the length direction of the pipeline body 1 are connected to the external pipeline through the connecting flange 2, the middle part of the pipeline body 1 runs through the bulkhead or splint of the cabin, and the external setting of the connection between the pipeline body 1 and the bulkhead or splint Th...

Abstract
The invention discloses a marine flange type pipe penetration piece. According to the technical scheme, the marine flange type pipe penetration piece comprises pipeline bodies, connecting flanges andsleeve bodies, wherein the connecting flanges are arranged outside the two ends of each pipeline body; the middle of each pipeline body is connected to the outside through the corresponding sleeve body; sleeve flanges are arranged outside each sleeve; a sealing piece is filled between each sleeve flange and the corresponding pipeline body; each sealing piece is arranged between the corresponding sleeve flange and the corresponding pipeline body, so that high vibration reduction performance can be achieved, and the sealing performance of the pipe penetration piece can be improved; and low-potential metal is only used in the area which cannot be reached by a high-conductivity medium, so that the high-conductivity medium is not in contact with the high-potential metal and the low-potential metal at the same time structurally, the problem of electrochemical corrosion is thoroughly avoided, and the service life of the pipe penetration piece is prolonged.
Description
technical field [0001] The invention relates to the technical field of ship engineering, in particular to a marine flange-type tank-through pipe fitting. Background technique [0002] In the hull, the through-tank pipe fittings are an important part of the ship's piping system, and they are pipe fittings that run through watertight cabins, decks, tanks, etc. and can maintain their respective seals. The tank fittings are generally composed of inner pipes and connecting surfaces. On the one hand, the inner pipes are connected to the hull pipeline connecting surfaces through the connecting surfaces, and on the other hand, they are directly or indirectly connected to ship structures such as bulkheads. The connecting surfaces can be flanges, threads, etc. In other forms, the inner pipe and connecting surface must ensure that the system medium will not leak. Commonly used tank fittings include copper bushing fittings (CB539-67) and steel fittings (CB / T 3480-92). The former uses c...
