Description
Grant Prideco pup joints are manufactured from the same material as our drill collars. Heat-treatment processes ensure a hardness range of 285-341 Brinell. Charpy V minimum impact strength of 40 ft-lb at 70° F are guaranteed one inch below the surface.
Grant Prideco integral drill pipe pups are heat treated to 120,000 psi minimum yield. Integral pups have the same tensile and torsional rating of S-135 drill pipe with the same pin ID. All connections are phosphate-coated to improve resistance to galling.
Standard lengths are 5 ft, 10 ft, 15 ft, and 20 ft. Additional sizes are available upon request.
Same-size pup joints 10 ft and longer can be produced as welded assemblies.
