The pup joint is a commonly used fitting in industrial pipe connection. According to different connections, it can be usually divided into thread and flange types. The threaded type can be further classified into two head external thread, single head external thread, and flat head external thread types. In addition, the product falls into tubing and casing types based on different uses.
This accessory for tubing is actually a short section of tubing. Compared with the tubing, it is just different in length. The product is manufactured in line with the API Specification 5CT, 5B and other related standards, and marked with the API logo. We can produce a variety of flat end and external upset tubing pup joints with J, N, L, and other steel grades and different specifications.
Technical performance
1. The pipe body enjoys large mechanical strength and good overall
performance.
2. The thread is processed by dedicated CNC machine tools, which
ensure high precision, reliable use, and long life.
3. The coupling adopts phosphating or copper plating, which
guarantees good wear resistance.
