Large diameter flanges are designed to the ASME B16.47 standard and can be manufactured out of any steel material grade. They come in flange faces that include:
- RTJ (Ring Type Joint)
- RF (Raised Face)
- FF (Flat Face)
Custom made large diameter flanges can come as large as the customer requires and made to their design specs. The forged flange is typically made out of a ring forging that gets machined to the final dimensions, either specified by ASME B16.47 or as requested as a custom size by the customer.
Uses for Large Diameter Flanges
Some of the most common applications for the large diameter flanges are for subsea / onshore pipelines and ASME pressure vessels.
