Core Function:

• They facilitate a transition between two pipes of varying sizes within a piping system.

Lap Joint Flanges

Lap joint flanges are a type of pipe flange connection composed of two main parts: a stub end and a lap joint ring flange. The stub end is welded to the pipe, and the lap joint ring flange fits over it, allowing for rotation and easy access for maintenance or repairs.

Threaded Flanges / Screwed Flanges / THRD-RF
 

• Threaded flange: used frequently in smaller piping systems and includes a threaded connection inside the flange bore, which does not require welding

Some of the most common types of threaded valve connections include:

• NPT: National pipe thread tapered, the US

Socket Weld Flanges (SWRF)

 

Socket-weld flange is similar in shape to a slip-on flange; however, a socket-welded flange differs in having a shoulder at the inner bore.

The slip-on flange has no shoulder at the inner bore.
