Description

ASTM A182 F1 F5 F9 F11 F12 F22 F91 ANSI B16.5/B16.47 BL Alloy Steel Blind Flange

Alloy steel is a type of steel alloyed with several elements such as molybdenum, manganese, nickel, chromium, vanadium, silicon, and boron. According to the different added elements and appropriate processing techniques, alloy steel can obtain special properties such as high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, and non-magnetic properties. Those have less than 5% alloy elements is are categorized as low alloy steel, these have alloy elements ranging from 5%-10% are categorized as minimum alloy steel, those have more than 10% alloy elements are categorized as high alloy steel.

Flanges made of alloy steel are widely used in water lines, oil, and gas, chemical plants, food production systems, etc. where high corrosion resistance, high temperature resistance and high pressure resistance are required.

Flange Type: Blind (BL)

Blind flanges manufactured in accordance with ASME B16.5 can be provided in Class 150 through Class 2500. It is basically a circular disc that does not have a hub or bored center. Bolts holes are drilled and aligned symmetrically along the circumferential edge of the solid disc. Generally the blind flange may be furnished with raised face (RF), ring join face (RJ), or flat face (FF). The blind flange serves a function similar to that of a plug or cap and is used to blank off the end of piping, valves and pressure vessel openings. It may be fabricated from cast, forgings, specific plates, or flat bars.
