ULMA Forja completes its already extensive offer of Forged Steel Flanges with Weld Overlayed / CLAD FLANGES at its Leniz facilities in Oñati

In oil and gas production and processing there are corrosive or abrasive fluids that cause damage to piping systems, process equipment and joining elements like flanges. These phenomena are often accelerated by high temperatures and pressures.

To increase the resistance of these highly exposed flanges, the surfaces that are in contact with the fluid are protected with Corrosion Resistant Alloys (CRA) using cladding/weld overlay technologies.

Cladding, also known as weld overlay, consists of overlaying a corrosion- or abrasion-resistant metal onto the base material by means of a welding process (manual or automatic).

This is a procedure by that uses an electric arc process to add a corrosion- or abrasion-resistant material on a carbon steel base material, seeking the lowest dilution, with the aim of obtaining a pure chemical composition with the lowest possible thickness.

In order to satisfy the growing demand of its clients, in August 2018 ULMA Forja installed its first state-of-the-art cladding cell in its facilities in Leniz (Oñati), thus completing its offer of solid flanges with weld overlay flanges.

Currently, ULMA manufactures a wide range of welded coatings on different base materials to improve resistance to corrosion or abrasion, and thus adapt to the most hostile environments, complying with the strictest specifications.

Our order book for weld overlay flanges includes three flagship projects currently being executed for oil and gas processing plants on the Arabian Peninsula, specifically in the United Arab Emirates, Oman and Qatar.
