• Blind Flange: Used to seal the end of a piping system or vessel opening.
• Weld Neck Flange: Provides a strong, long-lasting connection and is ideal for high-pressure applications.
• Slip-On Flange: Easy to install and adjust, suitable for lower pressure applications.
• Socket Weld Flange: Offers a smooth bore, reducing turbulence in the fluid flow.
• Threaded Flange: Allows for easy assembly and disassembly without welding.
• Lap Joint Flange: Provides flexibility in alignment and is easy to assemble.

When choosing a flange, consider factors such as:

• Operating pressure and temperature
• Chemical compatibility with the fluid
• Ease of installation and maintenance
• Cost-effectiveness for your application
• Compliance with industry standards (e.g., ASME/ANSI, API)
