Product Description--OCTG Casing Pup Joint Pipe
Pup joints are non-standard lengths of piping used to adjust the height of full length tubing, drill pipe, line pipe, or casing strings. Strings of pipe are assembled with standard length tubular goods that are typically 31 feet in length. As the drill string, production tubing, or casing is lowered into the well bore a pup joint is added to the pipe string in order to adjust the length of the string to its exact requirements.

Product advantage
1.Pup Joints are a mandatory part of equipment in almost any well.Compensate for standard range length tolerance of casing/tubing .
2.Due to their shorter length, they are typically easier to handle and to use.
3.At the same time, they provide the same performance as the tubing/casing/drill pipe that they are attached to.
4.Optimize handling of the down-hole equipment at the rig site.
5.Galvanic surfaces/ coatings possible.
