Weld neck pipe flanges attach to the pipe by welding the pipe to
the neck of the pipe flange. The allows for the transfer of stress from
the weld neck pipe flanges to the pipe itself. This also reduces high
stress concentration at the base of the hub of the weld neck pipe
flanges. Weld neck pipe flanges are often used for high pressure
applications. The inside diameter of a weld neck pipe flange is
machined to match the inside diameter of the pipe. Weld Neck Pipe
flanges with a hub have published specifications that range from 1/2"
thru 96". Coastal Flange provides Weld Neck pipe flanges in all
material grades, specifications and sizes.
Weld neck pipe flanges are typically provided with a
raised face, flat face, or RTJ facing. When a raised face is necessary
for weld neck pipe flanges, the standard height is 1/16" for weld neck
pipe flanges under 400#. For weld neck pipe flanges of 400# and up, the
standard weld neck pipe flange raised face height is 1/4".
Coastal Flange manufactures weld neck pipe flanges in
all steel material grades, including carbon weld neck pipe flanges,
stainless steel weld neck pipe flanges and alloy weld neck pipe
flanges. Coastal Flange also has many different weld neck pipe flanges
in stock and ready to ship. Weld neck pipe flanges in stock
include ANSI B16.5 weld neck pipe flanges, ASME B16.47 Series "A" weld
neck pipe flanges, ASME B16.47 Series "B" weld neck pipe flanges,
Pressure Vessel weld neck pipe flanges. Coastal Flanges also
