Committed for World Class Qualitative Socket Weld Flanges Manufacturing...
Socket Weld Flange Din En 1092-1 Is Connected To A Pipe With The Help Of A Single Fillet Weld, That Is Executed On The Outer Side Of The Flange. Although The Socket Weld Flange Is Different From The Slip-On Flange Type, Which Requires Two Welds. According To ASME B31.1, The Execution Of SW Flange Connection Using A Socket Weld Flange, Is By First Inserting The Pipe In The Socket Of The Flange Until It Reaches The Bottom Of The Flange.
This gap shall be left by the stainless steel & high nickel alloy socket weld flange manufacturer in india to allow proper positioning of the pipe inside the flange socket. This is done after the solidification of the weld. Socket Weld Flange Awwa C207 Class D is generally used for small-size and high-pressure piping systems that do not transfer highly corrosive fluid media. This because these API 6A SWRF Flange types are a subject to corrosion in the presence of a gap between the end of the pipe and the shoulder of the socket.
