Tubing D1 05” To 4 1 2” With Nu - China

price: 917.00 Dollar US$

Petroleum Tubing: Specifications 1.05”-4-1/2” with End Processing Forms NU (Non-Upset) and EU (Upset) Petroleum tubing is one of the essential devices in the process of oil extraction and transportation.

Its main function is to transport oil and natural gas from underground to the surface.

At present, the common specifications of petroleum tubing on the market range from 1.05 inches to 4-1/2 inches, which can meet the extraction requirements of different oil wells.

There are mainly two types of end processing forms for tubing: NU (Non-Upset) and EU (Upset).

The NU end processing form refers to no additional thickening treatment at the end of the tubing.

The advantage of this processing form is the lower cost, which is suitable for some wells with lower strength requirements.

The EU end processing form, on the other hand, involves thickening the end of the tubing, which can greatly increase the tensile and torsional strength of the tubing, enabling it to better adapt to high-pressure and complex downhole environments.
