Alloy 20 Plate Flange, Square Flange, Threaded Flange

Superior Quality ASTM B462 Alloy 20 Slip-on Flange, and Long Weld Neck Flange at competitive prices.

Creative Piping Solutions stands as a premier manufacturer of Alloy 20 flanges, renowned for their exceptional quality and precision engineering. Alloy 20 flanges are components made from a highly corrosion-resistant alloy known as Alloy 20. This material, also referred to as Carpenter 20, is a nickel-iron-chromium-molybdenum alloy with copper, which was developed for maximum resistance to acid attack, specifically sulfuric acid.

Alloy 20 Flanges are manufactured to meet various international standards and specifications, such as ASTM B462 (for forged or rolled alloy pipe flanges, forged fittings, and valves and parts for high-temperature service). Alloy 20 flanges are vital components in many industrial systems where corrosion resistance is a primary concern, ensuring durability and reliability in harsh environments.

ASTM B462 Alloy 20 (UNS N08020, WNR 2.4660) Flanges Supplier in different forms like Flat Face, Raised Face, RTJ, Lap Joint, Male and Female (M&F), Large and Small Tongue-and-Groove Flange.
