Flanges Supplier and Stockist – Pearl Steel
Flanges are essential mechanical components used to securely connect pipes, valves, pumps, and various other equipment in a piping system. Typically circular, these components come with evenly spaced bolt holes that ensure firm attachment and leak-proof sealing. At Pearl Steel, we provide a comprehensive range of high-quality Duplex Stainless Steel, Super Duplex Stainless Steel, High Nickel, stainless steel, Mild Steel, carbon steel, alloy steel and Titanium, engineered for superior reliability across multiple industries.
Common Materials Used in Flanges
Duplex Stainless Steel Flanges
Known for their excellent mechanical strength and superior resistance to pitting and stress corrosion cracking, Duplex Stainless Steel Flanges are widely used in pressure vessels, desalination systems, and structural piping in chemical industries.
Super Duplex Stainless Steel Flanges
These flanges, featuring higher chromium and molybdenum content, offer even greater corrosion resistance and strength. Ideal for offshore platforms, marine applications, and critical chemical processing operations, Super Duplex Flanges deliver outstanding durability under extreme conditions.
High Nickel Alloy Flanges
Our High Nickel Alloy Flanges (including grades like Inconel®, Monel®, and Hastelloy®) are engineered for extreme temperatures and aggressive chemical environments. They are highly sought after in aerospace, power plants, marine engineering, and acidic chemical processing.
Stainless Steel Flanges
Manufactured in grades such as SS 304, 316, and 321, our Stainless Steel Flanges are ideal for high-temperature, high-pressure, and corrosion-prone environments. Applications include food processing, pharmaceuticals, paper and pulp, and HVAC systems.
Mild Steel Flanges
Cost-effective and easy to machine or weld, Mild Steel Flanges are suitable for general structural use, low-pressure fluid conveyance, and basic engineering applications.
Carbon Steel Flanges
Renowned for their strength and impact resistance, our Carbon Steel Flanges are used in oil & gas transmission lines, refineries, power plants, and heavy industrial structures. Common standards include ASTM A105, A350 LF2, and A694.
Alloy Steel Flanges
Alloy Steel Flanges (such as ASTM A182 F5, F9, F11, F22) provide superior performance in elevated temperature and pressure environments. Used in petrochemical plants, steam lines, and high-stress industrial settings.
Titanium Flanges
Lightweight yet incredibly strong, Titanium Flanges offer unmatched corrosion resistance and biocompatibility. Commonly used in marine engineering, desalination plants, aerospace, and medical equipment manufacturing.
Manufacturing Process of Flanges
- Raw Material Inspection: High-grade materials such as Duplex Steel and Super Duplex Steel are quality-tested at the source to ensure chemical composition, dimension, and finish.
- Cutting & Forging: The raw metal is cut and forged into flanges using precision machinery. Products like Weld Neck Forged Flanges, Socket Welding Flanges, and Lap Joint Pipe Flanges are manufactured in this stage.
- Heat Treatment: Proper thermal processing enhances the mechanical and structural integrity of Duplex Flanges and Fittings for Heat Exchangers, ensuring performance in demanding environments.
- Inspection & Testing: Each flange—whether it’s a Super Duplex Steel Blind Flange or a Duplex Steel Long Weld Neck Flange—undergoes dimensional inspection, pressure testing, and surface treatment.
- Finishing & Packaging: Flanges like Super Duplex Steel Slip on Flanges, Stainless Steel Threaded Flanges, and Stainless Steel Plate Flanges are cleaned, marked, and packaged to prevent damage during transit.
Features of Our Flanges
- Bolt Hole Precision: All flanges are manufactured with accurately spaced bolt holes for secure and uniform attachment.
- Seal-Ready Faces: Raised or flat-face surfaces to ensure tight gasket sealing in critical applications.
- Diverse Range: We stock and supply every variety, from Slip-on Flanges Exporter-grade units to Super Duplex Steel Socket Weld Flanges.
