End protector system for tubular goods

Abstract

An end protector system for tubular goods including, but not necessarily limited to, drilling riser pipe. The end protector system utilizes lightweight substantially rigid, UV-stabilized molded plastic members that can quickly and easily cover box and pin end connections of drilling riser pipe, as well as ancillary conduit holes, bolt holes and/or other openings. The end protector system of the present invention can be used on tubular goods having an end connection flange, as well as those without an end connection flange, to block access to internal surfaces of the drilling riser components. The end protector system of the present invention further includes a retention system to ensure that individual end protectors remain in place during transportation and/or prolonged storage of such tubular goods.

1 . An apparatus, for covering a drilling riser end connection flange having a diameter, comprising:
 a. a cap comprising a substantially planar end and interconnecting side walls extending from said end, said end and walls defining a cavity, wherein said cap has a diameter larger than the diameter of said flange; and   b. a plurality of clip members attached to said sidewalls, said clip members adapted to be partially received on said end connection flange and fasten said cap to said flange.   
     
     
         2 . The apparatus of  claim 1 , wherein said cap comprises ultra violet stabilized molded plastic. 
     
     
         3 . The apparatus of  claim 1 , said cap further comprising at least one projection for receiving an ancillary tube attached to said drilling riser.
