Weld Neck Type Flange circumferentially welded into the system at its neck, allowing easy examination of the butt-welded area by radiography. The matching bores of both pipe and flange reduce turbulence and erosion inside the pipeline, making this flange ideal for critical applications.
| Weld Neck Type Flange Details | |
| Materials | Most standards specify the material requirements |
| Flange Sizes | All sizes and grades compatible to standard pipe ranges and wall thicknesses (pressure ratings) |
| Flange Face | Various configurations: flat face, raised face, tongue and groove, ring joint |
| Face Finish | Measured as Arithmetical Average Roughness Height (AARH). ANSI B16.5 specifies 125-500 AARH (3.2Ra to 12.5Ra). Other finishes available: 1.6Ra max, 1.6/3.2Ra, 3.2/6.3Ra or 6.3/12.5Ra |
Flanges connect pipes, valves, pumps and other equipment to form pipework systems, providing easy access for cleaning, inspection, or modification. Typically welded or screwed into systems and joined with bolts.
