Flanges Suppliers, Saudi Arabia
Flanges are forged or cast piping components that connect pipes, valves, and equipment using bolted joints, available in types including weld neck, slip-on, blind, socket weld, threaded, and lap joint per ASME B16.5 and B16.47. Manufactured from ASTM A105, A182, and A350 materials in pressure classes from 150 lb to 2500 lb. The GCC's massive oil and gas, petrochemical, and water infrastructure consumes enormous volumes of flanges, making Dubai and Dammam among the world's largest flange distribution centers.

Flanges are fundamental piping components used throughout the UAE and Saudi Arabia to create bolted connections between pipes, valves, instruments, and equipment. Manufactured per ASME B16.5 (NPS 1/2 to 24 inches) and ASME B16.47 Series A and B (NPS 26 to 60 inches), they are available in weld neck, slip-on, blind, socket weld, threaded, and lap joint types in pressure classes from 150 lb to 2500 lb.
Material specifications include ASTM A105/A105N for carbon steel, A182 F11/F22/F91 for alloy steel, A182 F304/F316 for stainless steel, and A350 LF2 for low-temperature service. Ring joint (RTJ) and raised face (RF) gasket surface finishes are both prevalent in GCC process piping, with RTJ being standard for high-pressure oil and gas applications.
The GCC region is one of the world's largest consumers of industrial flanges, driven by continuous investment in refineries, gas processing plants, petrochemical complexes, and water transmission infrastructure. Procurement managers must verify flange manufacturer approval status on the project AML, confirm marking per MSS SP-25, and ensure full material traceability. Dimensional verification, hardness testing, and PMI are standard quality checks. Major distributors in Jebel Ali and Dammam carry millions of dollars in flange inventory from globally approved manufacturers.
