Home > Alloy 28 Tube Fittings
Paul Tube Fittings, based in Houston, USA, is a reliable manufacturer and supplier of high-performance Alloy 28 Tube Fittings. Designed to withstand harsh corrosive environments, these fittings are perfect for the chemical, petrochemical, and marine sectors. Alloy 28 boasts exceptional resistance to acidic and chloride-rich substances, making it a go-to choice where standard stainless steels fall short. At Paul Tube Fittings, every fitting is crafted with precision to ensure leak-proof connections, robust mechanical strength, and a long lifespan. The company is dedicated to providing high-quality, tailored solutions that align with international standards and meet the specific needs of demanding industrial applications.
Alloy 28 Tube Fittings are crafted from a highly corrosion-resistant nickel-iron-chromium alloy, containing 26–28% chromium, 30–32% nickel, 3–4% molybdenum, and trace amounts of copper. This alloy excels in resisting strong acids like sulfuric, phosphoric, and nitric acids, and it also stands up to chloride-induced stress corrosion cracking. With a typical tensile strength of about 620 MPa (90,000 psi) and a yield strength of 280 MPa (40,000 psi), Alloy 28 offers impressive toughness and durability, even under extreme pressure and temperature conditions, making it perfect for critical tubing systems in corrosive chemical processing environments.
