5083 Aluminium marine grade flange classification

Marine flat welding flange
It is a flange welded by inserting the pipe into the inner ring of the flange. The flat welding flange is divided into two types: the neck flat welding flange and the plate lap welding flange.
Marine butt welding flange
Also known as high-neck flange, it refers to a flange with a neck that has a round pipe transition and is butt welded to the pipe.
Marine loose flange
Also known as loose flanges, pipes are generally made of high-cost materials. In order to reduce costs, internal connections of the same material as the pipes and flanges of different materials are used, which is to use flanges, steel rings, etc. On the pipe end, the flange can move on the pipe end.
Loose flanges are generally used on copper-nickel alloy pipes and expansion joints.

5083 Aluminium marine hydraulic flange

The pressure of ship hydraulic piping system is very high, so special socket type high pressure method flange is adopted. The flange thickness is about 30mm-45mm depending on the pipe diameter. This kind of flange generally uses a concave flange and a convex flange to connect Method, use O-ring as sealing material.
