ASTM B16.5 Socket Weld Pipe Flanges manufacturer
The ASTM B16.5 socket weld pipe flange, abbreviated as SWF, is similar to a slip-on flange, except only one fillet weld is made to the flange and pipe. Pipe is welded to ASTM B16.5 socket weld pipe flanges by inserting the pipe into the socket and backing the piping out between 1/16” and 1/8”. This is to prevent the expanding pipe on the inner side of the weld from expanding when headed and cracking the weld on the fitting.
There are a couple different methods for ensuring that the pipe has enough clearance when welding. The first is by inserting the pipe fully into the flange and marking the pipe. Then remove the pipe so that the marking has moved 1/16” to 1/ 8” and make the weld.
The other method is by using a tool . The use of tool should be considered when designing a piping system. The reason for this is over time, the tool may dislodge itself from the flange and travel downstream of the flange.
