Available in Carbon Steel, Stainless Steel, Alloy Steel, Duplex, and Nickel alloys.

International Standards

ASME, ANSI, EN, DIN, ISO compliant.

Export strictly to Bahrain

We export flanges to Bahrain with complete documentation.

Flange Solutions for the Marine and Offshore Industry

Given Bahrain's island geography and its extensive maritime and offshore oil activities, our industrial flanges are heavily utilized in marine environments. We specialize in supplying Cupro-Nickel (Copper-Nickel 90/10 and 70/30) and Monel 400 flanges which provide unparalleled resistance to seawater corrosion, biofouling, and stress corrosion cracking in desalination plants and offshore platforms.

Supporting the Aluminum Industry

Bahrain is home to one of the world's largest aluminum smelters. To support this key industry, we provide industrial flanges that can withstand the abrasive and aggressive chemicals used in the refining of bauxite and the smelting process. Our heavy-wall flanges and specialized alloy flanges ensure continuous, safe operation of the piping systems within these massive industrial complexes.

Stringent Dimensional Accuracy

In all structural and piping assemblies, dimensional accuracy is crucial for quick and stress-free installation. Our flanges undergo rigorous automated inspections. The bolt hole pitch circle diameter (PCD), flange thickness, and hub tapers are verified to be strictly within the tolerances specified by ASME B16.5, reducing fit-up time and welding costs for contractors across Bahrain.

Rapid Response and Stock Availability

To support emergency maintenance, shutdowns, and turnaround projects (TAR) in Bahrain's refineries, we offer rapid response manufacturing. We maintain an extensive inventory of raw steel billets and forgings, allowing us to quickly machine and dispatch flanges, minimizing costly downtime for our clients and keeping essential industrial operations running smoothly.
