We are one of the Top manufacturers, suppliers, wholesalers and distributors of SORF Flanges along with some other high quality stainless steel products. We carry these excellent variety of flanges which are recognised by its inside diameter that is slightly bigger than pipe’s outside diameter. These flanges are widely exported in many industries like petroleum and chemical. UAE, Saudi Arabia, Kuwait, Qatar, Egypt, Turkey, Oman, Africa, Malaysia & many countries in USA & Europe are the main market business for our industry. Slip on pipe flanges are typically provided with raised or flat face flanges. The sizes of these flanges are easily available 15 NB to 48" 1200NB. With customised requirements we also provide the best material of stainless steels such as carbon steel and nickel alloy steel. The standards for each product differ with ANSI B16.5, ANSI B16.47, ANSI B16.36, ANSI B16.48, BS 4504, EN1092, UNI 2277/2278, and DIN. Flange Face Type includes Flate Face (FF), Raised Face (RF), Ring Type Joint (RTJ with classifications 150 LBS, 300 LBS, 600 LBS, 900 LBS, 1500 LBS, 2500 LBS, DIN Standard ND-6,10, 16, 25, 40. The Coating/Surface Treatment which can be applied to these flanges are Anti-rust Paint, Oil Black Paint, Yellow Transparent, Zinc Plated, Cold and Hot Dip Galvanized. For each material the grades differ from each other, they are set under different categories like for Stainless Steel Slip on Raised Face Flanges it’s ASTM A182, A240 F 304, 304L, 304H, 316, 316Ti, 316H, 316L, 316LN, 309S, 309H, 310S, 310H,317, 317L, 321, 321H, 347, 347H, 201, 202, 904. For Carbon Steel Slip on Raised Face Flanges it’s ASTM A105/A105N, A350 LF1, LF2 CL1/CL2, LF3 CL1/CL2, A694 F42, F46, F48, F50, F52, F56, F60, F65, F70, A516.60, 65, 70 (Spectacle Blind Flange, Spacer Ring/Spade Flange), Steel RST37.2, C22.8. For Alloy Steel Slip On Raised Face Flanges the grades are as ASTM A182 F1,F5,F9,F11,F22,F91.With some great benefit of Nickel Alloy Slip On Raised Face Flanges the grades include ASTM SB564, SB160, SB472, SB162 Nickel 200 (UNS No. N02200), Nickel 201 (UNS No. N02201), Monel 400 (UNS No. N04400), Monel 500 (UNS No. N05500), Inconel 800 (UNS No. N08800), Inconel 825 (UNS No. N08825), Inconel 600 (UNS No. N06600), Inconel 625 (UNS No. N06625), Inconel 601 (UNS No. N06601), Hastelloy C 276 (UNS No. N10276), Alloy 20 (UNS No. N08020.
