Marine flange inside two common

Marine welding flange: the tube is inserted into the inner flange welded flanges, welded flange into flat welding flange with neck and lap welding plate flange two kinds. Flat welding Hydraulic tube fittings Hydraulic tube fittingsadvantages of simplicity, low production costs, but not high temperature high pressure, mainly used for pressures below 2.5 MPa at room temperature piping, the ship uses the most flanges.Marine welded flange:Hydraulic pipe fittingsHydraulic pipe fittings as high-neck flange, with neck refers to the transition of a pipe and the pipe flange welded connection. Greater rigidity easily deformed welded flange, sealed, widely used for high pressure and temperature of the occasion, nominal pressure PN at 16MPa or so. Mainly used for compressed air piping, piping carbon dioxide.
