Blind flanges are used to blank off the ends of piping, valves and pressure vessel opening. From the standpoint of internal pressure and bolt loading, blind flanges, particularly in the larger sizes, are the most highly stressed of all flange types. Blind flange is also used in the flange of the import and export of the equipment, which is used to connect the two equipment. Blind flange is installed at the end of piping system either on a header or branch connection or on valve and functions as a mean for positive isolation of the piping system. Piping headers can be terminated at the ends using a butt weld cap. However the cap is often substituted by a blind flange if a provision for future extension of the header is required. On drain systems blind flanges serve as important rodding points or can be diamantled for easy inspection. Blind flanges are avaliable in the same pressure rating as weld neck flanges and with various gasket facing. Fromthe standpoint of internal pressure and bolt loading, blind flanges, particularly in the larger sizes, are the most highly stressed flange types. However, most of these stress are bending types near the center, and since there is no standard inside diameter, these flanges are suitable for higher pressure temperature applications.
The industrial processes come into die forging,and machining,we can provide a wide range of flanges,following on standards like ASME B16.5 Flange , ASME B16.47 Flange, DIN 2573 Slip On Flange, DIN 2631 Welding Neck flange, JIS Flange 5K SOP Flange and JIS Flange 10K SOH Flange. ASME Flange include ASME B16.5 Flange, ASME B16.47-A Flange, ASME B16.47-B Flange, this standard system include slip on flange, blind flange, welded neck flange, Threaded Flange, lapped joint flange (loose flange), socket welded flange, B16.36 Orifice Flange, long Weld Neck Flange and Special Flange, sizes from 1/2 inch to 60 inch, class 150, class 300, class 600, class 900, class 1500, class 2500.
