Description
- The present application is a continuation of U.S. Patent Application having U.S. Ser. No. 17/517,337, filed Nov. 2, 2021, which is a continuation of U.S. Patent Application having U.S. Ser. No. 17/360,641, filed Jun. 28, 2021, which is a conversion of U.S. Provisional Application having U.S. Ser. No. 63/045,317, filed Jun. 29, 2020, which claims the benefit under 35 U.S.C. 119(e). The disclosure of which are hereby expressly incorporated herein by reference.
- The present disclosure relates to a thread protector for a threaded end of a unit of casing or tubing that can be quickly attached to and removed from the unit of casing or tubing. The present disclosure also relates to a method of attaching or removing the thread protectors from the pin end of the units of casing or tubing.
- Casing and/or tubing have a pin end and a box end. The box end includes threads inside, which are naturally protected by being disposed inside the tubing or casing. The pin end has threads on the outside of the tubing or casing that are exposed and can be damaged. Currently, there are protective devices for the pin end threads of the tubing or casing but they take a considerable amount of time to put on the tubing or casing and remove from the tubing or casing. When you multiply the time it takes to put on or remove a typical protector device from the pin end threads of multiple units of tubing or casing, it results in a large amount of time. This large amount of time is taken directly from production time of an oil or gas well.
- Accordingly, there is a need for a thread protector for the threads of the pin end of the tubing or casing that can be more quickly placed on and/or removed from the pin end of the tubing or casing, but still protects all the threads of the pin end of the tubing or casing.
- The present disclosure is directed toward a thread protector that has an external sleeve to protect pin threads disposed on a pin end of a tubular member. The thread protector also has a flange disposed on a first end of the external sleeve to engage with the pin end of the tubular member. The thread protector further includes a securing apparatus extending from the flange to frictionally engage an inside portion of the tubular member to maintain position of the thread protector on the tubular member.
- The present disclosure is also directed toward a method of protecting pin threads of pin ends of tubular members. The method includes screwing the thread protector on pin threads of a pin end of a tubular member.

If a limited number of the threads on thetubular member 16 are engaged to secure thethread protector 10 thereto, then the reduction in time it would take to remove thethread protector 10 from thetubular member 16, and the time it would take to secure thethread protector 10 to thetubular member 16, when combined for numerous tubular members, would be significant. - In one embodiment, the number of
threads 12 on the inner side 28 of theexternal sleeve 26 of thethread protector 10 can be less than ten threads. In another embodiment, the number ofthreads 12 on the inner side 28 of theexternal sleeve 26 of thethread protector 10 can be less than eight threads. In a further embodiment, the number ofthreads 12 on the inner side 28 of theexternal sleeve 26 of thethread protector 10 can be less than six threads. In yet another embodiment, the number ofthreads 12 on the inner side 28 of theexternal sleeve 26 of thethread protector 10 can be less than four threads. In another embodiment, the number ofthreads 12 on the inner side 28 of theexternal sleeve 26 of thethread protector 10 can be less than three threads. In a further embodiment, the number ofthreads 12 on the inner side 28 of theexternal sleeve 26 of thethread protector 10 can be less than two threads. - The
threads 12 on thepin end 14 of thetubular member 16 can extend along a certain length of thetubular member 16. The engaged threads (threads extending from the end of the pin end of the tubular member that are engaged by the threads of the thread protector) extend a certain percentage of the length of all thethreads 12 on thepin end 14 of thetubular member 16. In one embodiment, the length of the engaged threads are less than about 40 percent of the total length of all thethreads 12 on thepin end 14 of thetubular member 16. In another embodiment, the length of the engaged threads are less than about 30 percent of the total length of all thethreads 12 on thepin end 14 of thetubular member 16. In a further embodiment, the length of the engaged threads are less than about 25 percent of the total length of all thethreads 12 on thepin end 14 of thetubular member 16. In yet another embodiment, the length of the engaged threads are less than about 20 percent of the total length of all thethreads 12 on thepin end 14 of thetubular member 16. In an even further embodiment, the length of the engaged threads are less than about 10 percent of the total length of all thethreads 12 on thepin end 14 of thetubular member 16. In another embodiment, the length of the engaged threads are less than about 5 percent of the total length of all thethreads 12 on thepin end 14 of thetubular member 16. - Referring now to
