Norris pup joints are furnished in grades J-55.
They are available upset one or both ends and in combination right
or left hand threads. All pup joints are manufactured from new
full weight seamless tubing and are color coded. After upsetting
and threading, each pup joint is then hydrostatically tested to
meet the strict API-5CT specification. Each Norris pup joint carries
code numbers which permanently link it to file copy records documenting
every detail of raw material, testing, manufacturing processes
and quality control measures. Also available are full body normalized
and perforated pup joints.
