As
the name suggests slip on pipe flanges can easily get slipped all over the
pipe’s surface. These are generally machined with an inner diameter that is
slightly larger than the pipe’s outer diameter. Slip on pipe flanges can get
secured to the pipe with a fillet weld at the bottom or top surface of slip on flanges. Typically slip on pipe
flanges can be found in the market having a flat or a raised face.
Being
bored a slip on flange can easily slip on the pipe so the pipe’s end remains
within the flange of fraction of an inch from the flange face. The pipe’s end
has been cut square. Flange bolt holes are aligned and flange face is squared
to the pipe. Then a filled weld can be run around that end of pipe schedule to fuse it
within the bore of flange. Another fillet weld can be run around the back end
of flange hub fusing it to the pipe’s outer part. Slip on pipe fittings are the
most common types of welding flanges. Prior to the making of final full fillet
welds, temporary welds are made until the position and alignment gets certain.
Being much loose they can easily slip on over the pipe and clamp onto a rolled
or flanged over pipe edge.
In
case of raised face slip on flanges,
the standard height must be 1/16” for slip on pipe flanges within 400#. For
slip on pipe flanges, the standard height is 1/16” for slip on pipe flanges
within 400#. Slip on pipe fittings of 400# and more, the average height for
raised face is 1/4”.
