ASTM B729 UNS N08020 Nickel Alloy Steel Tube
Overview
ASTM B729 is a standard specification that outlines the requirements for seamless UNS N08020 (also known as alloy 20) nickel alloy pipes and tubes. UNS N08020 is a highly corrosion-resistant alloy that consists of nickel, chromium, molybdenum, and copper.
Alloy 20 (UNS N08020) offers excellent resistance to general corrosion, pitting, and crevice corrosion in various environments, including sulfuric acid, phosphoric acid, acetic acid, and chloride-containing solutions. It is widely used in industries such as chemical processing, pharmaceuticals, food processing, and petrochemicals.The ASTM B729 specification provides guidelines for the dimensions, mechanical properties, heat treatment, and other requirements for seamless alloy 20 pipes and tubes.

Uses&Application
1>.Chemical Processing: Alloy 20 is widely used in chemical processing plants for equipment such as reactors, heat exchangers, valves, pumps, and storage tanks. Its resistance to sulfuric acid, phosphoric acid, and other corrosive chemicals makes it suitable for handling corrosive substances.
2>.Food Processing: ASTM B729 N08020 is also employed in the food processing industry, specifically in applications where corrosion resistance is vital. It is utilized in equipment like mixers, evaporators, cookers, and storage tanks that handle food products with high acidity or chloride content.
3>.Petrochemical Industry: The alloy finds its utility in the production and processing of petrochemicals. It is used in refining equipment, storage tanks, and piping systems exposed to corrosive petrochemical substances.
4>.Pharmaceuticals: Due to its resistance to acidic environments, Alloy 20 is employed in pharmaceutical manufacturing facilities for equipment such as reactors, vessels, and piping systems.
5>.Power Generation: ASTM B729 N08020 is also found in power plants, particularly in flue gas desulfurization systems, where it is exposed to corrosive gases and liquids.
