How to using ship flange?
Brief introduction of Ship flanges; connection of Ship flanges, Ship flanges is used for flange on the ship, flange is to make the pipe and pipe connected to each other parts. Connect to tube ends. The flange has holes, and can be worn through bolts to make the two flanges tightly connected. The flange is sealed with a gasket. Flange connection is the two pipes, fittings or equipment, first fixed on a flange, between the two flanges, plus flange pad, bolted together to complete the connection. Some pipe fittings and equipment have their own flange, also belong to the flange connection, Classification 1 Marine flat welding flange is the pipe into the flange inner ring welding flange, flat welding flange is divided into flange with neck welding flange and plate lap welding flange two kinds. Flat welded flange has the advantages of simple manufacturing, low production cost, but not high temperature and high pressure resistance, mainly used for atmospheric temperature pipeline with pressure less than 2.5 MPa, is the most used flange in ships. 2 Marine butt welding flange, also known as high neck flange, refers to the flange with neck and pipe transition and pipe butt welding connection. Butt-welding flange is hard to deform, well sealed, widely used, suitable for high pressure and temperature occasions, nominal pressure PN in about 16 MPa. It is mainly used for compressed air piping system and carbon dioxide piping system. 3. Loose-sleeve flange, also known as looper flange, is generally made of pipeline material with high cost. In order to reduce the cost, the use of pipeline with the same material and different material combination of flanges, is the use of flanging, rings and other flange sleeve on the end of the pipe, flange can move on the end of a pipe fittings. Loose flange is usually used for copper nickel alloy pipe and expansion joint. 4 Marine hydraulic flange ship hydraulic pipeline pressure is very high, so all use plug-in high-pressure method, flange thickness according to the pipe diameter is about 30 mm-45 mm, this flange generally uses a concave flange and a convex flange connection, using O-ring as sealing material.
