304 Stainless Steel Flange
Paslanmaz çelik 304 Flanşlar 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, dayanıklılık, and resistance to oxidation and mild chemical environments. They are ideal for use in industries such as chemical processing, petrol ve gaz, yiyecek ve içecek, su arıtma, 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, bağcıksız, kör, dişli, and socket weld—they conform to international standards like ASME B16.5, EN 1092-1, and DIN specifications. Paslanmaz çelik 304 flanges are an economical and reliable solution for connecting pipes, vanalar, pompalar, and other equipment in corrosive environments where long-term performance is essential.
