Spectacle Blind Flange, ASTM A182 F316L Stainless Steel Figure 8 Flange, RF ASME B16.48
Spectacle Blind Flange, also known as Figure 8 Flange, is combination of the two which can be rotated to function as a Single Bind or a Ring Spacer. This flange is generally a piece of metal than is cut to fit between two pipe flanges and usually sandwiched between two gaskets. A spectacle blind flange is often made from two metal discs that are attached to each other by a small section of steel. The flange shape is similar to a pair of glasses or spectacles, hence it's called Spectacle Bind Flange. Our Group can supply Spectacle Blind Flange with different type of joint face (RF, FF, RTJ) in series class of 150/300/600/900/1500/2500 in according to dimensional standards ASME B16.48.
ASTM A182 F316L is a standard specification for forged or rolled alloy and stainless steel pipe flanges, fittings, valves, and parts for high-temperature service. A spectacle blind flange is a type of flange that is used to separate or isolate sections of a piping system. It consists of a pair of metal discs that are attached to each other by a central bolt or hinge. The discs can be rotated to either block or allow flow through the pipeline. The ASTM A182 F316L spectacle blind flange is specifically made from grade 316L stainless steel, which is a low-carbon version of 316 stainless steel. This material offers improved corrosion resistance and is often used in applications where welding is required. The spectacle blind flange is commonly used in piping systems where regular maintenance or inspection is required. By simply rotating the discs, the flow of fluid can be easily shut off without the need to remove or disconnect any pipes. This makes it a convenient and practical solution for various industrial applications.
