304 Flensa Baja Tahan Karat
Baja Tahan Karat 304 Flensa are versatile and corrosion-resistant components widely used in piping systems for fluid and gas transport. Manufactured from austenitic stainless steel grade 304, these flanges offer excellent strength, daya tahan, and resistance to oxidation and mild chemical environments. They are ideal for use in industries such as chemical processing, minyak dan gas, makanan dan minuman, pengolahan air, and general industrial applications. SS 304 flanges are compatible with high and low temperature operations and are known for their good weldability and machinability. Available in various types—such as weld neck, tergelincir, buta, berulir, and socket weld—they conform to international standards like ASME B16.5, EN 1092-1, dan spesifikasi DIN. Baja tahan karat 304 flanges are an economical and reliable solution for connecting pipes, katup, pompa, and other equipment in corrosive environments where long-term performance is essential.
