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 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

The ASME B16.48 standard covers operating line blanks in sizes NPS 1â??2 through NPS 24 for installation between ASME B16.5 flanges in the 150, 300, 600, 900, 1500, and 2500 pressure classes. A line blank is a pressure-retaining plate that is used to block off a section of pipe. It is typically made of steel or cast iron and has a variety of features, including a raised face, flat face, or grooved face. The ASME B16.48 standard specifies the dimensions, tolerances, materials, and markings for line blanks. There are two main types of line blanks: Spectacle blind flanges: These have a solid end and an open end connected by a web or tie bar. Paddle blanks: These are similar to the solid end of a spectacle blind flange, but they have a plain radial handle. Line blanks are used in a variety of applications, including: To isolate a section of pipe for maintenance or repair To prevent the flow of fluid in a pipe To provide a test point for a piping system The ASME B16.48 standard is an important specification for the design and manufacture of line blanks. It ensures that line blanks are safe and reliable, and that they meet the requirements of the applicable codes and regulations.
