Recognized by their long tapered hub, these flanges are butt-welded directly to the pipe. The hub transfers stress from the flange to the pipe, making them the standard choice for high-pressure, severe-condition applications.
These flanges slip over the outside of the pipe and are welded both inside and outside to provide strength and prevent leakage. They are cost-effective and easier to align than weld neck flanges.
Manufactured without a center bore, blind flanges are used to blank off the ends of piping systems, valves, and pressure vessel openings. They endure high stress from internal pressure.
Designed primarily for smaller-diameter, high-pressure piping. The pipe is inserted into the socket of the flange and secured with a single fillet weld on the outside, ensuring a smooth internal bore.
Used in conjunction with a "Stub End" fitting. The flange itself is not welded to the pipe, allowing it to rotate freely for easy alignment of bolt holes. Highly economical for systems utilizing expensive alloy pipes.
Unlike permanent welds, flanged joints allow for quick dismantling, making inspection, modification, and cleaning of piping systems highly efficient.
Precision-machined facings (such as Raised Face and Ring Type Joint) ensure an impeccable, leak-proof seal even in high-vibration environments.
Strict adherence to ASME B16.5 and EN 1092 standards guarantees exact bolt-hole alignment for seamless mating with valves and pumps.
Fully backed by Mill Test Certificates (MTC) with Heat Numbers, Size, and Class stamped directly on the flange edge for transparency.
