API 5CT OCTG Tubing Data Sheet


Refers to the chemical composition, mechanical strength of YS (Yield Strength), TS (Tensile Strength), Elongation and hardness.

The API external-upset-end (EUE) tubing pipe is broadly used due to the fact that is a good, serviceable interconnection in the majority of wells.


Without the need of modifying the actual thread shape, the joint dimension will increase because of upsetting procedure. The EUE joint features a designed joint strength in tension and pressure strength much higher than that of the pipe overall body and, as a result, is considered a 100% joint effective connection.


To enhance seal efficiency of API EUE tubing in high-pressure system, a grooved coupling, which accepts nonmetallic seal rings, is quite often applied in the coupling. API EUE joints come in OD sizes of 1.050 to 4.500 inch.
