Flange Facing Types Explained The flange facing (sealing surface) is critical for creating a leak-tight joint. Different facing types are designed for specific pressure ranges, temperatures, and sealing requirements. Raised Face (RF) Most Common Type Raised sealing surface (1.6mm or 6.4mm height) Concentric or spiral serrations for gasket grip Suitable for Class 150-2500 Works with […]
Understanding Lap Joint Flanges A Lap Joint Flange consists of two components: a stub end and a backing flange. The stub end is butt-welded to the pipe, while the backing flange rotates freely around it, allowing for easy bolt hole alignment during assembly. Design Features Two-piece construction: stub end + backing flange Backing flange rotates […]
