Hebei high pressure flange pipe group Co., Ltd. is a professional production and sales of flange, elbow, pipe fittings.
Marine flange connections
A marine flange is a flange used on a ship, which is a part of a pipe and pipe. Connected to pipe end. There are holes on the flange, and can be used to make the two flange tight. Gasket seal between flanges.
Flange connection is the two pipes, pipe fittings or equipment, the first fixed on a flange, flange between the two, plus the flange pad, bolted together to complete the connection. Some pipe fittings and equipment have their own flange, flange connection is also.
Is the pipe is inserted into the inner ring flange welding flange, divided into hubbed flange plate and a welding flange two.
The advantages of flange is simple in manufacture, low production cost, but not resistant to high temperature and high pressure, the pressure is lower than the normal line is mainly used for 2.5 MPa, is the most used flange.
Marine flange
Also known as high neck flange, refers to the neck with a circular tube and the tube and the transition of the flange.
Butt weld flange is not easy to deformation, good sealing, wide application, suitable for high pressure temperature, nominal pressure PN in 16MPa. The utility model is mainly used for compressed air piping and carbon dioxide piping.
Marine loose flange
Also called loose flanges, generally the pipe material cost is very high, in order to reduce the cost of the pipeline inner connecting piece with the same material and different material of flange combination is the use of flanging, the flange steel ring set in the pipe end, a flange in pipe end activities.
Loose flanges are commonly used in copper nickel alloy pipes and expansion joints.
Marine hydraulic flange
Marine hydraulic piping pressure is very high, so the use of socket type high pressure side flange special, flange thickness according to different diameters in 30mm - 45mm, the general flange connected by a concave convex flange and a flange, with O ring as the sealing material
