Blind Flanges manufactured by Pipe Fittings Supplier. These types of flanges are a kind of plate for covering or closing the end of any kind of steel pipe which are bolted together. Many times when nozzles is blanked off or even closed it as covered for pressure test in plant, the flange is also used for tank pipe line to close up the top end of the pipe or tube. It is widely used in many industries like petrochemical, oil, liquid and gas to check the flow by testing process. Blind flange dimensions are covered in ASME B 16.5 which also covers Pipe Flanges and Flanges size NP 1/2” to 24” for above NPS” to 60”. The specification for Stainless Steel is as ASMT A 182, A 240 with grades F 304, 304L, 304H, 316, 316L, 316Ti, 310, 310S, 321, 321H, 317, 347, 347H and 904L. ASTM A 105, ASTM A 181 are the grades for carbon steel. ASTM A 182, GR F1, F11, F22, F5, F9, and F91 are grade for Alloy Steel. These products also come in Copper, Brass and Gunmetal. The class is differentiated by 150#, 300#,400 #,600#,900#, 1500# & 2500 #.
