These flanges are made exclusively from stainless steel grades 304, 304L, 316, and 316L, designed for corrosion-resistant applications in chemical, petrochemical, and water treatment systems. Available in sizes from DN15 to DN2000 (1/2 inch to 36 inches), they conform to ASME, ANSI, JIS, BS, and DIN standards. Configurations include slip-on, lap joint, and threaded types, each suited for specific installation methods and pressure conditions.
The 304L and 316L variants have lower carbon content to reduce sensitization risk during welding, making them suitable for welded assemblies in aggressive environments. Material composition follows ASTM A182 and EN 10088-2, with typical chromium levels of 18 - 20% and nickel content of 8 - 12% for 304, and 10 - 14% for 316. Surface finish is standard mill finish, with no plating or coating applied unless specified.
These flanges are used in systems handling corrosive fluids, seawater, and high-purity chemicals where contamination must be avoided. Buyers include engineering firms in pharmaceutical, marine, and food processing industries. Packaging includes export-grade wooden crates with mill test certificates included. Trade terms are negotiable, with FOB and CIF options available. Lead time is approximately 35 to 50 days depending on size and quantity.

Before ordering, verify that the material grade matches the intended service environment - 316L for chlorides, 304L for general corrosion resistance. Request certified material test reports for each heat lot, including chemical analysis and tensile results. Confirm that the flange dimensions comply with ASME B16.5 or DIN 2532 drawings for your piping system.
Confirm Incoterms with the supplier - FOB is standard, but CIF may include insurance costs. Lead time typically ranges from 35 to 50 days due to custom sizing and material sourcing. Payment terms are usually 30% deposit with balance before shipment. Ensure packaging is sealed against moisture and labeled with handling instructions for ocean freight.
Conduct a pre-shipment inspection for surface defects, dimensional accuracy, and thread integrity. Use a caliper and surface roughness gauge to validate tolerances. Ensure each flange is stamped with the material grade and heat number. Retain samples for future quality audits, particularly in high-risk applications like offshore or pharmaceutical systems.
