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 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

A Blind Flange is a solid disk used to block off a pipeline or to create a stop. Like a regular flange, it also has mounting holes around the perimeter and the gasket sealing rings machined into the mating surface. The difference is that a blind flange has no opening to allow fluid to pass through.
