What Are Blind Pipe Flanges?
This video teaches about the different flanges that connect pipes in plumbing systems and custom-made metal structures. Blind flanges close off the ends of water and gas pipes. Blind pipe flanges are often used in high-pressure applications where the lines cannot be welded or threaded together and require a permanent sealing solution. The most common type of blind flange is the socket-welded type which requires no welding or other processes for installation.
Blind flanges are steel or cast iron with different materials for specific applications. The blind pipe flanges are most commonly used when you want to seal the end of a pipe or tube and prevent leakage. You can install a blind flange by pressing it over the end of your pipe and tightening it down with a bolt. Since they are not welded onto your pipe, you can remove them without damaging the rest of your system.
Blind pipe flanges are also part of complex metal structures such as bridges and buildings. The outer walls of these structures may be made out of metal sheets, which need to be sealed. Blind pipe flanges come in different sizes depending on their function. Blind flanges are made from metal or plastic.
