A swivel flange is a pipe joint that connects two pieces of pipe. It can rotate freely, offering flexibility for applications where pipes need to move independently. This feature makes swivel flanges invaluable in industries such as oil and gas, where pipelines may encounter shifting conditions like thermal expansion or ground settlement.

A swivel flange comprises two main parts: the flange and the swivel nut. The flange is a flat disk with holes drilled for bolts or nuts. The swivel nut enables the pipe to rotate freely while staying firmly attached. This feature ensures that when pressure or movement happens between two pipes, they can move separately without putting too much strain on either. Consequently, it’s a perfect choice for pipe movement while maintaining a secure connection.
