Forged Flanges

Flanges are parts designed to join the pipes, valves, pumps and other units (components) in a piping system. In addition, they facilitate access for cleaning, inspection and modification.
Two flanges are attached with bolts and a seal between them to prevent any possibility of leakage.
There are many different standards for flanges in the market. However, our flanges are manufactured according to specific regulations and standards to guarantee their functionality and ensure they can be replaced.
ULMA’s forged steel and fully machined flanges are manufactured in compliance with the specifications ASME B16.5, ASME B16.47 and MSS SP-44.

Full range: from ½ to 102 inches, all pressure classes & all material grades.

In addition, ULMA can also design, calculate and manufacture non-standard flanged joints (from A to Z design, calculation, manufacturing and testing) guaranteing the integrity, serviceability and durability of the flanged joint (flange + gasket +  bolts + nuts).
