Weld Neck Flange Manufacturers in China
ASME B16.5 weld neck flange are usually available in a raised face, flat face, or RTJ facing Types. If raised face is required for weld neck pipe flanges, the standard height is 1/16" for Stainless Steel Weld Neck Flange under 400#. For weld neck pipe flanges of 400# and up, the standard Carbon Steel weld neck raised face flange raised face height is 1/4".
Weld neck flange attach by welding the pipe to the neck of the flange which transfers stress from the flange to the pipe instead. WN RF reducing flange are often used for applications where high pressure is a factor. Inside diameter of the Inconel weld neck raised flange is designed to match the pipe's inside diameter. We are leading weld neck flange manufacturers in China.
