Chanchai Stainless, based in Bangkok, Thailand, is a premier manufacturer, supplier, and exporter of high-grade Stainless Steel Orifice Flanges catering to clients worldwide. With years of expertise in precision engineering, the company delivers orifice flanges in a wide variety of sizes, shapes, and specifications to meet diverse industrial needs. Known for their tensile strength, corrosion resistance, and long-term reliability, these flanges are designed to handle critical operations in demanding environments. By combining modern technology, strict quality standards, and customer-focused solutions, Chanchai Stainless ensures that every orifice flange offers durability, efficiency, and superior performance across multiple industries.
Stainless steel orifice flanges are manufactured from premium grades such as 304, 316, and 316L, which contain chromium (16–20%), nickel (8–12%), and molybdenum (2–3% in 316). These alloys offer excellent corrosion and oxidation resistance, ensuring durability in aggressive environments. The flanges exhibit high tensile strength (up to 515 MPa), good ductility, and resistance to stress corrosion cracking, making them reliable under high-pressure and high-temperature conditions. The precise orifice plate integrated within these flanges ensures accurate flow measurement, while their smooth finish, structural integrity, and ease of installation enhance operational safety and efficiency.
