Spectacle Blind Flange

A spectacle blind flange is a safety device used to isolate a section of pipeline or equipment when they need to be inspected or removed from piping system. It is not like a valve, the spectacle blind flange is a permanent or long term isolation block. The spectacle blind flange is made of two pieces metal discs which are joint together by a part of steel handle. The two discs are connected by a hinge, so that the blind flange can be rotated to open or close the pipeline. Technical Specifications a. Material: Carbon steel, stainless steel, alloy steel b.

A spectacle blind flange is a type of isolation device used in piping systems. It is a forged steel plate that consists of two interconnected discs: a ring with a hole of the same bore size as the pipeline, and a solid disc. In normal conditions, the spectacle blind is installed in the open position and does not interrupt the flow of the fluid conveyed by the pipeline. To stop the flow, the blind end is rotated into place between the flanges. Spectacle blinds are available in standard sizes up to 24 inches and in forged material grades like ASTM A105 (high-temperature carbon), A350 low-temperature carbon), and various ASTM A182 grades (alloy, stainless steel, duplex). They are typically used in conjunction with flanges, and are available with raised face (RF), flat face (FF), or RTJ faces. Technical Specifications of Spectacle Blind Flange Material: Carbon steel, low-temperature carbon steel, stainless steel Standard: ASME B16.48 Size: Up to 24 inches Face: RF, FF, RTJ Handle: Yes

A blind and spacer flange is a type of flange used to isolate a section of pipe or equipment. It is made up of two parts: a solid disc called the "spade" and a ring with a hole in the center called the "spacer". The spade is inserted into the spacer and then bolted in place between two flanges. This creates a barrier that prevents fluid flow through the pipe. Blind and spacer flanges are used in a variety of applications, including: 1. Maintenance and repair 2. Testing and commissioning 3. Decommissioning 4. Temporary isolation Technical Specifications 1. Material: Steel, stainless steel, or other non-corrosive materials 2. Size �½â?? inch to 24â?? Inch 3. Face finish: Raised face, Flat face, or Grooved face 4. Pressure class: 300, 600, 900, 1500 or 2500 psi Benefits Blind and spacer flanges offer a number of benefits, including: â?¢ They are a cost-effective alternative to isolation valves. â?¢ They are easy to install and remove. â?¢ They provide a reliable seal against fluid flow. â?¢ They are available in a variety of sizes and materials to meet the needs of different applications. Applications Blind and spacer flanges are used in a variety of industries, including: 1. Oil and gas 2. Chemical 3. Power 4. Water treatment 5. HVAC
