The Alloy 20 Long Weld Neck Flanges from Ting Flanges are primarily made up of nickel (30–35%), chromium (19–21%), and iron, along with trace amounts of copper, manganese, silicon, and molybdenum. This specific blend provides outstanding resistance to oxidation, corrosion, and nitric acid. On the mechanical side, these flanges boast a tensile strength of around 70,000–90,000 psi, a yield strength of 30,000–50,000 psi, and an elongation of 25–40%, ensuring they can withstand high pressure and temperature conditions. The combination of their alloy makeup and mechanical strength makes them perfect for tough industrial environments.
Alloy 20 Long Weld Neck Flanges are extensively used in industries where there is a need for superior corrosion resistance, especially in sulfuric acid-containing environments, chlorides, and other aggressive chemicals. Typical uses include chemical processing, petrochemical plants, and pharmaceutical industries. These flanges are best suited for high-temperature and high-pressure systems because of their strong mechanical properties and resistance to stress corrosion cracking. Moreover, their seamless fit into piping systems provides leak-free connections, and hence they are best suited for storage tanks, heat exchangers, and pipelines for corrosive fluids or gases.
