PUP JOINTS
Pup Joints for Easy Surface Handling & Drilling Practices
Pup Joints are commonly used to adjust the length of the drill string to the elevation of rotary table for easy surface handling and drilling practices. They undergo the same stresses as drill pipe and their performance depends primarily on their superior mechanical properties.
Pup Joints are short drill pipe used to adjust the length of the drill string and are ordered to match all drill pipe dimensions.

Product Performance
Pup Joints are manufactured from AISI 4145H or 4140H-modified alloy, heat-treated to a Brinell Hardness range of 285-341 with a Charpy “V” notch minimum impact strength of 40 ft/lb at 70° F and one inch below the surface. Pup Joints are heat-treated to 110,000 PSI minimum yield. All connections are phosphate coated to impede galling during initial make-up.
They are available in standard lengths of 5’, 10’, 15’ and 20’ with other configurations upon request.
Integral Pup Joints dedicated to Sour Service applications are available. PJ -110 PUP S are Sour Service Pup Joint using ASCOWELL C material providing improved resistance to Sulfide Stress Cracking with high yield strength.
Operational Benefits
COMMAND-SMFI offers a wide range drill string products and accessories with standard API or proprietary highperformance
connections to meet the most demanding drilling requirements.
