Product Details:

AASHISH METAL & ALLOYS is a reputed manufacturer and exporter of ANSI Flanges, offering high-quality, precision-engineered flanges that meet stringent international standards and customer expectations across various industries. Our ANSI (American National Standards Institute) flanges are manufactured in compliance with ANSI/ASME B16.5 and B16.47 standards, covering flange sizes from ½” to 48” and pressure classes ranging from Class 150 to Class 2500. These flanges are crucial components for connecting pipes, valves, pumps, and other equipment in a secure and leak-proof manner, making them essential for pipeline integrity in a wide range of fluid and gas transport systems.

We manufacture ANSI flanges using premium-grade materials such as stainless steel, carbon steel, alloy steel, duplex steel, copper alloys, and nickel-based alloys to ensure excellent mechanical strength, corrosion resistance, temperature tolerance, and durability. Our production line supports a range of surface finishes including mirror finish, black finish, galvanized coating, anti-rust oiling, and CNC-machined finishes for improved sealing capability and surface protection. Each flange is subjected to rigorous quality inspections and tests such as hydro testing, ultrasonic testing, PMI (Positive Material Identification), and dimensional verification to ensure compliance with ANSI specifications.

Aashish Metal & Alloys produces a wide variety of ANSI flange types to suit multiple installation and pressure requirements. These include Weld Neck Flanges, Slip-On Flanges, Blind Flanges, Socket Weld Flanges, Lap Joint Flanges, Threaded Flanges, and Orifice Flanges. Each type is designed for specific functions—whether it’s to allow for easy assembly/disassembly, facilitate inspection and cleaning, or provide reinforcement in high-pressure piping systems. Weld neck flanges are preferred for critical applications due to their long tapered hub which provides structural strength and reduces stress concentrations. Slip-on flanges are easy to align and cost-effective, while blind flanges are used to terminate pipeline ends or isolate a piping section.

Applications of ANSI flanges from Aashish Metal & Alloys span across sectors such as oil & gas, petrochemical, refinery, water treatment, power generation, marine, chemical processing, shipbuilding, pulp and paper, and HVAC systems. They are used in both onshore and offshore projects where safety, reliability, and compliance are of utmost importance. Our flanges are engineered for performance in high-temperature, high-pressure, and corrosive environments.

We offer complete customization options based on customer drawings, specifications, and international project requirements. With a dedicated engineering team, advanced CNC machining facilities, and robust inventory management, we ensure prompt delivery and consistent product quality. Flanges are typically marked with relevant details including size, pressure class, material grade, heat number, and batch number for traceability.

• Packaging Details: At Aashish Metal & Alloys, we understand that safe and secure packing is critical to maintaining the quality and integrity of ANSI Flanges during storage, handling, and international shipping. We follow international packing standards to ensure that every flange reaches its destination free from corrosion, damage, or deformation. 🛠️ Standard Packing Methods: 1. Wooden Boxes / Crates (Fumigated) Heavy-duty sea-worthy wooden boxes made from fumigated pinewood or plywood. Ideal for bulk packaging of flanges of various sizes. Internal compartmentalization using wooden blocks or separators to prevent contact or damage. Properly nailed and strapped to withstand handling and stacking during sea freight. 2. Palletized Packing Flanges stacked in layers over strong wooden pallets, separated by plastic sheets or cardboard. Secured using stretch film, bubble wrap, and steel/plastic straps. Shrink-wrapped for moisture resistance and loaded as per weight-bearing capacity. Commonly used for large or uniform flange shipments. 3. Individual Wrapping (Corrosion Protection) Each flange is individually wrapped in polyethylene plastic, oil-paper, or anti-corrosion VCI paper. All carbon steel flanges are coated with anti-rust oil or varnish before packing. For stainless steel or alloy flanges, protective caps are used on faces to avoid scratches and surface damage. 📋 Packing Details Include: Item Name and Size Pressure Class and Material Grade Quantity per Box/Crate Gross Weight and Net Weight Heat Number and Batch Code Customer PO Number or Tag Marking Export Labels (if required by client) 🌍 Export Compliance: All packages are heat-treated and comply with ISPM 15 regulations for international shipping. Export packing is suitable for air freight, sea freight, or inland transport. Flanges are packed to withstand moisture, rough handling, and long transit times. 🔒 Optional Packing Add-ons (On Request): Custom branding / logo stenciling on boxes QR code tagging or
