Abstract
A threaded union for tubulars used for high-pressure fluid applications includes a unitary nut supported by at least two nut retainer segments received under a top wall of the nut in an annular segment retainer groove in one of the tubulars. The nut retainer segments fully support the unitary nut. The nut retainer segments are held in the annular segment retainer groove by limiting travel of the nut or by securing the nut retainer segments in the segment retainer groove.
Claims (20)

a unitary nut having a top wall, an outer sidewall, an inner sidewall and a depending skirt defining a box thread that engages a pin thread on a male end of the second tubular, the top wall extending past the inner sidewall to define a top flange that extends to and closely surrounds an outer sidewall of the first tubular; and at least two P-shaped nut retainer segments for supporting the top flange of the unitary nut, the P-shaped nut retainer segments having a head portion and a depending leg portion, the head portion being closely received in an annular segment retainer groove in an outer sidewall of the mating end of the first tubular and the depending leg portion substantially filling a gap between the inner sidewall of the unitary nut and the outer sidewall on the mating end of the first tubular.
a unitary nut having a top wall, an outer sidewall, an inner sidewall and a depending skirt defining a box thread that engages a pin thread on a male end of the second tubular, the top wall extending past the inner sidewall to define a top flange that extends to and closely surrounds an outer sidewall of the first tubular; and at least two P-shaped nut retainer segments for supporting the top flange of the unitary nut, the P-shaped nut retainer segments having a head portion and a depending leg portion, the head portion being closely received in an annular segment retainer groove in an outer sidewall of the mating end of the first tubular and the depending leg portion substantially filling a gap between the inner sidewall of the unitary nut and the outer sidewall on the mating end of the first tubular.
2. The threaded union as claimed in claim 1 further comprising an annular relief groove at a top of the inner sidewall of the unitary nut to inhibit the unitary nut from binding on the P-shaped nut retainer segments.
3. The threaded union as claimed in claims 1 or 2 further comprising at least one travel-limit block attached to the top wall of the unitary nut, the at least one travel-limit block ensuring that the unitary nut cannot slide far enough over the first tubular to permit the P-shaped nut retainer segment to fall out of the annular segment retainer groove.
4. The threaded union as claimed in claims 1 or 2 further comprising at least one O-ring received in at least one O-ring groove in an outer sidewall of the P-shaped nut retainer segments to hold the P-shaped nut retainer segments in the annular segment retainer groove.
5. The threaded union as claimed in claims 1 or 2 further comprising a pin slidably received in a smooth bore in a top wall of respective ones of the at least two P-shaped nut retainer segments and a set screw received in a threaded bore in an outer sidewall of respective ones of the at least two P-shaped nut retainer segments, the threaded bore communicating with the smooth bore so that the set screw can be tightened against a bottom end of the pin to force the pin into contact with a top surface of the annular segment retainer groove to retain the respective P-shaped nut retainer segments in the annular segment retainer groove.
6. The threaded union as claimed in claim 5 wherein the pin further comprises a smooth shaft and a head that is larger than the smooth shaft.
7. The threaded union as claimed in claims 5 or 6 further comprising a box thread in a top end of the smooth bore for receiving a collar having a pin threaded outer wall, the collar surrounding the shaft of the pin and permitting the shaft to reciprocate freely there through, but preventing the head of the pin from passing so that the pin cannot fall out of the smooth bore.
8. The threaded union as claimed in claims 1 or 2 further comprising a U-shaped spring clip received in a spring clip groove in the head portion of respective ones of the at least two P-shaped nut retainer segments, the spring clips having spring clip ends that engage respective top and bottom surfaces of the annular segment retainer groove when the respective P-shaped nut retainer segments are inserted into the annular segment retainer groove.
9. The threaded union as claimed in claim 8 wherein the spring clip further comprises inward bends near the spring clip ends, the inward bends engaging locking notches in the spring clip grooves to lock the respective spring clips in the respective spring clip grooves.
10. The threaded union as claimed in any one of claims 1-9 wherein the unitary nut comprises a wing nut.
11. A threaded union for first and second tubulars having mating ends, comprising:
a unitary nut having a depending skirt defining a box thread that engages a pin thread on a male end of the second tubular, and a top flange that extends to and closely surrounds an outer sidewall of the first tubular; and at least two P-shaped nut retainer segments for supporting the top flange of the unitary nut, the P-shaped nut retainer segments having a head portion and a depending leg portion with an outer sidewall that extends in a straight line from a top surface of the head portion to a bottom surface of the depending leg portion, the head portion being closely received in an annular segment retainer groove in an outer sidewall on the mating end of the first tubular while the depending leg portion substantially fills a gap between the inner sidewall of the unitary nut and the outer sidewall on the mating end of the first tubular.
a unitary nut having a depending skirt defining a box thread that engages a pin thread on a male end of the second tubular, and a top flange that extends to and closely surrounds an outer sidewall of the first tubular; and at least two P-shaped nut retainer segments for supporting the top flange of the unitary nut, the P-shaped nut retainer segments having a head portion and a depending leg portion with an outer sidewall that extends in a straight line from a top surface of the head portion to a bottom surface of the depending leg portion, the head portion being closely received in an annular segment retainer groove in an outer sidewall on the mating end of the first tubular while the depending leg portion substantially fills a gap between the inner sidewall of the unitary nut and the outer sidewall on the mating end of the first tubular.
12. The threaded union as claimed in claim 11 further comprising a nut retainer segment holder to hold the P-shaped nut retainer segments in the annular segment retainer groove.
13. The threaded union as claimed in claim 12 wherein the nut retainer segment holder comprises the unitary nut and the threaded union further comprises a nut travel limiter to ensure that the unitary nut holds the P-shaped nut retainer segments in the annular segment retainer groove.
14. The threaded union as claimed in claim 13 wherein the nut travel limiter comprises one of:
at least one travel-limit bolt received in a threaded bore in a sidewall of the first tubular above the annular segment retainer groove; and at least one travel-limit block secured to a top surface of the unitary nut.
at least one travel-limit bolt received in a threaded bore in a sidewall of the first tubular above the annular segment retainer groove; and at least one travel-limit block secured to a top surface of the unitary nut.
