LONGAN FLANGE

Pressure Vessel Flange series

Pressure vessels are common in petrochemical, power, and light industries. Types include flat welding, long-neck butt-welding and forged tube sheets and baffle plates.

Slip-on flanges

Our slip-on flanges are designed to easily slide over pipes, featuring an inside diameter slightly larger than the pipe's outside diameter. Connected via fillet welds at both the top and bottom. Ideal for applications requiring ease of installation and adjustment, as they lack a weld bevel, allowing for flexibility in pipe length. While commonly used in lower pressure systems, they can also be made with a lap joint style for enhanced connection strength when needed.
