API 5CT Pup Joint

API 5CT Pup Joint

Introduction A pup joint is a pipe without standard length. API SPEC 5CT pup joints are used to adjust the height of full length tubing or casing strings to exact requirement. They are also applied to adjust the depth of downhole tools. In order to cater to the needs of customers, JST is offering a broad range of API SPEC 5CT OCTG pup joints.


1. API SPEC 5CT pup joints are tubing with short length, and are used for spacing out downhole assemblies, as well as handling tubing accessories.
2. With our sophisticated manufacturing facility, we produce these joints by using high grade raw materials (which are sourced from vendors of high repute) and cutting edge technology to ensure their sturdy design and longer functionality.
3. API SPEC 5CT pup joints can be ordered individually or in set.
4. Checking these OCTG pup joints with the assistance of quality controllers guarantees their resistance against abrasion and longer service life.
5. Locating on site gives the operator the flexibility of adjusting location depths of downhole assemblies, such as spacing out tubing hanger when sealing.
