A mechanical part used to connect pipes, valves, pumps, or other equipment in a piping system
A flange is a mechanical part used to connect pipes, valves, pumps, or other equipment in a piping system. It provides a strong, sealed joint that can also be easily assembled or disassembled for maintenance or inspection.
🔩 Definition
A flange is a flat, circular disc (usually made of metal) that is bolted to another flange with a gasket in between to create a tight seal.
⚙️ Main Functions
Connects pipes, valves, or equipment together
Allows disassembly for inspection, cleaning, or repairs
Provides strength and alignment to the piping system
Seals the joint to prevent leaks
🧱 Common Flange Types
Weld Neck Flange (WN): Welded to the pipe; used for high pressure/temperature
Slip-On Flange (SO): Slipped over the pipe and then welded; easy to install
Socket Weld Flange (SW): For small-size, high-pressure pipes
Blind Flange (BL): Used to close the end of a pipe
Threaded Flange (TH): Screwed onto pipes without welding
Lap Joint Flange (LJ): Used with a stub end; good for frequent dismantling
📐 Example
If you have two sections of pipe that need to be joined together:
You weld or thread a flange onto each pipe end
Place a gasket between them
Bolt the two flanges together to make a tight, leak-proof connection
