Product Description

API Tubing and Casing Pup Joint
Tubing and Casing Pup Joints are machined according to the latest version of API Spec 5CT. It's used to connect two pipes of same diameter with the same types of thread on the two ends.
The Steel Grade includes J55,K55,N80-1, N80Q, L80-1, P110 etc.
There are two types of thread widely used in Tubing pup joint:Non-upset Thread(NUE) and External-upset Thread(EUE)
There are three types of thread widely used in Casing pup joint: Long-Round Thread(LTC), Short-Round Thread(STC),Buttress Thread(BTC)
There are two types of End thread: Pin*Pin, Pin*Box(Pin*Pin with coupling)

API Crossover
Crossover is also kind of pup joint, used to connect two pipes of different diameter with the same or different types of thread on the two ends.
The OD, Length and thread type etc. are customized.
API tubing and casing pup joints are short sections of tubing or casing that are used to connect two longer sections together. They are typically used in oil and gas drilling operations to extend the length of the tubing or casing string.

The term "pup joint" refers to the fact that these sections are shorter than the standard lengths of tubing or casing. They are typically available in lengths of 2, 4, 6, 8, 10, or 12 feet, although custom lengths can also be manufactured.

API tubing and casing pup joints are manufactured to meet the specifications of the American Petroleum Institute (API). This ensures that they are made from high-quality materials and have undergone rigorous testing to ensure their strength and durability.

These pup joints are threaded on both ends, allowing them to be easily connected to other sections of tubing or casing using coupling connections. They are available in various sizes and grades to accommodate different drilling conditions and operating pressures.

API tubing and casing pup joints are essential components in the oil and gas industry, as they provide a flexible and convenient way to connect and extend tubing or casing strings. They are used in a variety of applications, including drilling, completion, and production operations.
