Nickel Pipe Alloy 20 Schedule 40 Seamless is a corrosion-resistant seamless pipe made from a nickel-chromium-iron alloy containing 32-38% nickel, providing excellent resistance to sulfuric acid, sulfur gases, and other harsh chemicals found in chemical processing, pulp and paper, and petroleum refining industries. With standardized Schedule 40 wall thicknesses, it offers improved pressure handling capabilities while maintaining superior corrosion resistance compared to lighter pipe schedules, making it suitable for handling aggressive chemical process streams.
