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.
