Flanges
Aury Africa supplies a wide range of high-quality flanges used in piping systems across mining, industrial, and process applications. Flanges are critical components that allow for the safe and efficient joining of pipes, valves, pumps, and other equipment. Our flange range includes mild steel, stainless steel, and HDPE-compatible flanges, available in various pressure ratings and dimensions to meet the diverse requirements of high-pressure fluid systems. These flanges are manufactured to conform to global standards such as SANS, ANSI, DIN, and BS, ensuring interchangeability and long-term reliability in new installations or maintenance projects.
What Are Flanges?
Engineered for demanding environments, Aury flanges are used in slurry lines, water reticulation systems, dewatering setups, and process pipelines where durable, leak-proof sealing is essential. Their machined faces and uniform bolt hole configurations ensure even pressure distribution and optimal gasket seating. Combined with appropriate gaskets and fasteners, flanges provide a robust and serviceable joint that allows for easy disassembly during maintenance or reconfiguration. All flanges supplied by Aury are inspected for flatness, roundness, and material integrity, and can be supplied in either plain, raised face, or ring-type joint styles depending on the application. With a commitment to material traceability, quality control, and technical support, Aury Africa ensures that every flange delivers the strength, alignment, and sealing confidence required in mission-critical piping systems.
Built for Harsh Environments
Our flanges are designed to perform in the most challenging industrial conditions, including high-pressure slurry systems, corrosive chemical pipelines, and fluctuating temperature zones. Each flange is available in multiple pressure classes, typically ranging from PN6 to PN40 and ANSI 150 to ANSI 600, depending on the application requirements. The materials used are selected for their mechanical strength, impact resistance, and corrosion performance, making them suitable for both surface and underground installations.
We also offer flanges with protective coatings such as hot-dip galvanising, epoxy paint, or corrosion-resistant alloys for harsh, high-humidity or chemical-exposed environments. These protective features ensure the flanges resist premature degradation and deliver consistent sealing over extended operational lifespans.
Application Versatility
Aury flanges are installed across a wide range of process systems. In mining operations, they are used in slurry pipelines, dewatering lines, tailings transport, and chemical dosing systems. In industrial facilities, flanges connect high-pressure air, water, and gas pipelines. Their design also allows for integration with HDPE piping via backing rings or stub flanges, enabling hybrid systems that combine flexibility and strength.
Thanks to the availability of multiple flange face types including flat face, raised face, and ring-type joint, our flanges are adaptable to various gasket materials and sealing requirements, ensuring leak-free operation in both static and vibrating systems.
Material Options and Standards
We supply flanges in a variety of materials to suit different operating conditions. Common options include:
-
Carbon steel (for general-purpose use)
-
Stainless steel 304 and 316 (for corrosive or high-hygiene environments)
-
Mild steel (cost-effective and easy to fabricate)
-
HDPE-compatible backing rings (for fusion-welded plastic systems)
All flanges comply with global manufacturing standards, including SANS, ANSI, DIN, and BS specifications. This ensures compatibility with international equipment and piping specifications, and simplifies procurement for multi-vendor installations.
Engineering for Performance
All flanges supplied by Aury Africa are manufactured to exacting standards with tight tolerances for flatness, roundness, and bolt pattern alignment. This level of precision ensures consistent gasket compression, proper bolt torque distribution, and maximum joint integrity. The result is a reliable, high-performance seal that can withstand internal pressure, external forces, thermal expansion, and vibration.
Our flanges are engineered to support repeated assembly and disassembly cycles without warping or compromising performance, making them ideal for pipelines requiring regular inspection, cleaning, or re-routing.
