Class 300 Pipe Flanges

Class 300 pipe flanges are crucial for creating efficient and reliable piping systems in various applications. By choosing the right type and ensuring they meet industry standards, you can enhance the safety and performance of your systems.

Types of Pipe Flanges
Weld Neck Flanges: Known for their long, tapered hub, these flanges are ideal for high-pressure and high-temperature applications. They provide a strong connection and reduce stress concentrations.
Slip-On Flanges: Easy to install, these flanges are slipped over the pipe and welded in place. They are suitable for low to medium-pressure systems.
Blind Flanges: Used to seal the end of a piping system or vessel, these flanges are essential for isolating sections of a system for maintenance.
Threaded Flanges: These flanges have internal threads and can be screwed onto the pipe without welding, making them ideal for low-pressure applications and systems requiring frequent disassembly.
Socket Weld Flanges: Designed for small-diameter, high-pressure pipes, these flanges have a socket into which the pipe is inserted and then welded.
Lap Joint Flanges: Used with stub ends, these flanges are ideal for systems requiring frequent dismantling for inspection and cleaning.
