Our Class 150 flanges are produced in accordance with ASME and ANSI standards, guaranteeing accurate dimensions, dependable performance, and durability. These flanges, which come in a variety of sizes and materials, are perfect for systems that run at moderate temperatures and low pressures. Serving customers in industries like water treatment, HVAC, oil & gas, and general engineering, Harsh Flanges places a high priority on product quality, prompt delivery, and customer satisfaction.
Depending on the needs of the application, ANSI B16.5 Class 150 Flanges are usually made of alloy steel, carbon steel, or stainless steel (grades 304, 316). Iron, carbon, chromium, nickel, and molybdenum are among the elements that make up their composition, which adds strength and resistance to corrosion. These flanges have an approximate yield strength of 150–300 MPa, a tensile strength of 400–600 MPa, and an elongation of 20–30%. In general industrial settings, they provide reliable sealing, structural integrity, and resistance to moderate thermal and mechanical stress. They are made for low-pressure applications and can withstand up to 285 psi at 100°F.
Harsh Flanges, a leading supplier in Mumbai, India, offers an extensive selection of ANSI B16.5 Class 150 Flange, including weld neck flanges, slip-on flanges, blind flanges, threaded flanges, and lap joint flanges.
