JIS B2220 is the Japanese industrial standard for steel pipe flanges. The 10K rating is the most common pressure class for general-purpose applications. This Stainless Steel Slip-On (SOP) flange is designed to slide over the pipe and be fillet welded on both sides. Made from grades like SUS304 or SUS316, it offers excellent corrosion resistance for water, oil, and chemical lines. Its compact design and ease of alignment make it a staple in Japanese-designed machinery and shipbuilding worldwide.
