Product description
ASTM A182 F316L STEEL STAINLESS BLIND SPECTACLE FLANGE B16.48
ASTM A182 F316L is a specification for forged or rolled alloy and stainless steel pipe flanges, fittings, valves, and parts for high-temperature service. It is commonly used in industries such as oil and gas, chemical, and petrochemical.
A spectacle flange is a type of flange that consists of a pair of rotating discs or "spectacles" attached to each other by a central bolt. It is used to separate or isolate sections of a pipeline or to provide access for inspection or maintenance.
The blind spectacle flange is a specific type of spectacle flange that has one solid disc and one rotating disc. The solid disc is used to close or "blind" the pipeline, while the rotating disc allows for visual inspection or access to the pipeline.
B16.48 refers to the American Society of Mechanical Engineers (ASME) standard for line blanks. It specifies the dimensions, tolerances, and materials for line blanks used in piping systems.
In summary, ASTM A182 F316L steel stainless blind spectacle flange B16.48 is a specific type of flange made from stainless steel alloy (F316L) that is used to close or blind a pipeline while allowing for visual inspection or access. It meets the standards set by ASME B16.48 for line blanks.

APPLICATION OF ASTM A182 F316L STEEL STAINLESS BLIND SPECTACLE FLANGE
One possible application of an A182 F316L stainless steel blind spectacle flange (B16.48) is in the oil and gas industry. This type of flange is commonly used in pipeline systems to provide a removable closure at the end of a pipeline or to isolate a section of the pipeline for maintenance or repair.
The blind spectacle flange is designed with a solid plate that completely blocks the flow of fluid through the pipeline when installed. It is typically used when there is a need to close off a pipeline temporarily or permanently, such as during pressure testing, equipment installation, or system shutdown.
The A182 F316L stainless steel material is chosen for its excellent corrosion resistance, high strength, and durability. This makes it suitable for use in harsh environments, such as offshore oil rigs or chemical processing plants, where the flange may be exposed to corrosive fluids or high temperatures.
The B16.48 standard specifies the dimensions, materials, and testing requirements for blind spectacle flanges. It ensures that the flange meets the necessary safety and performance standards for its intended application.
