The plate on the SS 904L ub6 Plate Flange extends the surface area available for welding, bolting, and other forms of fastening. Flanges meet all relevant international standards, including but not limited to ASTM B649. These flanges come in a wide variety of sizes and pressure ratings, from 1/2 inch up to 48 inches. A weld neck and a raised face characterise the ASME SA182 SS 904L WNRF Flanges. These flanges' necks and faces are welded for further strength, and their pressure classes go from 150 to 2500 and PN6 to PN64.
Flanges like this have a wide range of applications, from the energy industry to the pharmaceutical and petrochemical industries. Heat exchangers, boilers, condensers, the paper and pulp industries, offshore oil drilling, and the manufacture of chemical and saltwater equipment all make use of SS DIN 1.4539 Nippo Flanges.
