Threaded tubular end protector

Abstract

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 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. A method of protecting the pin threads of the pin ends of the tubular members. The method includes screwing the thread protector on the pin threads of the pin end of the tubular member.

What is claimed is: 
     
         1 . A thread protector, the thread protector comprising:
 an external sleeve to protect pin threads disposed on a pin end of a tubular member;   a flange disposed on a first end of the external sleeve to engage with the pin end of the tubular member; and   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.   
     
     
         2 . The thread protector of  claim 1  further comprising a plate that extends within the flange. 
     
     
         3 . The thread protector of  claim 2  wherein the securing apparatus includes a first spoke member supported by the flange or the plate, the first spoke member has spoke ends that can frictionally engage the inside of the tubular member. 
     
     
         4 . The thread protector of  claim 3  wherein the securing apparatus further includes a rod member extending from the first spoke member to a second spoke member. 
     
     
         5 . The thread protector of  claim 4  wherein the second spoke member has a second set of spoke ends that can frictionally engage with the inside of the tubular member. 
     
     
         6 . The thread protector of  claim 5  wherein outer edges, radially and axially, of the second set of spoke ends are tapered to ease insertion of the securing apparatus of the thread protector into the tubular member. 
     
     
         7 . A method of protecting pin threads of pin ends of tubular members, the method comprising:
 screwing a thread protector on pin threads of a pin end of a tubular member, the thread protector comprising:
 an external sleeve to protect pin threads disposed on a pin end of a tubular member; 
 a flange disposed on a first end of the external sleeve to engage with the pin end of the tubular member; and 
 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. 
   
     
     
         8 . The method of  claim 7  further comprising a plate that extends within the flange. 
     
     
         9 . The method of  claim 8  wherein the securing apparatus includes a first spoke member supported by the flange or the plate, the first spoke member has spoke ends that can frictionally engage the inside of the tubular member. 
     
     
         10 . The method of  claim 9  wherein the securing apparatus further includes a rod member extending from the first spoke member to a second spoke member. 
     
     
         11 . The method of  claim 10  wherein the second spoke member has a second set of spoke ends that can frictionally engage with the inside of the tubular member. 
     
     
         12 . The method of  claim 11  wherein outer edges, radially and axially, of the second set of spoke ends are tapered to ease insertion of the securing apparatus of the thread protector into the tubular member.
