A pup joint is a pipe of non-standard length used to adjust the length of tubular strings to its exact
requirement. There are 2 kinds of pup joints according to API 5CT standard: one
is for casing pipe, the other is for tubing. All the pup joints are
made from new prime API raw materials and are identifiable
throughout the manufacturing process via mill certifications and
other trace-ability measures.
