Carbon steel flanges are ideal for their ability to withstand high pressure and temperature, making them the appropriate joining method for most pipe joints for most critical service conditions. Flanges provide stronger and more durable connections, easier assembly and disassembly, better leak prevention, more versatility in connecting different pipe sizes and materials, the ability to handle slight misalignments, and are for more reusable without causing damage compared to other welded or threaded connections.

SPFA stock a core range of common standards and sizes, many of which are certified to multiple dimension and material specifications when the standards overlap. Many of the larger sizes are stocked in a semi-finished very heavy wall and are machined according to the required finished size, face and weld prep.
