Features of DIN 2503 Stainless Steel Flanges
● High-quality materials: made of high-quality stainless steel materials, such as 304, 316, etc., with excellent corrosion resistance and high temperature resistance.
● Standardized design: following DIN 2503 standard, the flanges' dimensions, pressure ratings and other parameters are in line with international standards, which makes it easy to interchange and connect with other standard flanges.
● Various types: including flat weld flanges with neck, butt weld flanges, threaded flanges and other types, each of which has its specific design features and applications.
● Excellent sealing performance: the sealing surfaces of the flanges are precision machined, and when used with gaskets, they can provide reliable sealing performance and prevent medium leakage.
