What a weld pipe nipple and close pipe nipple?


Weld pipe nipple
Weld nipples have no threads and connect to tube fittings by welding versus threading. Weld nipples are suitable to be used under extreme conditions like vibration, pressure surges and changes of temperature. Weld nipples are not weakened by the cut threads which can reduce the wall thickness and therefore weaken the structural strength.

Close Pipe Nipple
CloseA close nipple has no unthreaded area which means that when two female fittings are screwed tightly onto both ends of the nipple, very little of the nipple will still be exposed. When ordering a close nipple, they are ordered by the diameter by close, for example 1/2″ x close.
