CYLINDRICAL THREADED CONNECTION WITH UNIFORM INTERFERENCE

A cylindrical threaded connection in which most of the threads between the slightly tapered pin end and the slightly tapered box end have free running radial clearance therebetween. One or two revolutions of thread near the pin end or near the box opening have reduced root dimension or enlarged cres...

Beschreibung
Zusammenfassung:	A cylindrical threaded connection in which most of the threads between the slightly tapered pin end and the slightly tapered box end have free running radial clearance therebetween. One or two revolutions of thread near the pin end or near the box opening have reduced root dimension or enlarged crest dimension to provide uniform interference in the last revolution or so of complete connection makeup. This uniformly spreads the load over the axial distance of the interference.
