External Upset Tubing

Upsetting is a forging process that makes for a thicker wall on the tube ends.

Upset Tubing (EUE) is a long tubing with a joint installed in a wellbore to facilitate the extraction of oil and gas. The tubing joints are designed to suit a certain well type, based on the underground conditions and fluids.

It acts as a conduit, through which the produced fluids or gas get transmitted from the bottom to the surface.

The tubing joint is relatively a single length pipe that can vary in length anywhere from 25 to 30 ft.

This ideal length allows easy production as the tubing joint is fitted with threads on both sides and can run down through a well of any depth.

Types of Integral Connections:

1. The upsetting process has enhanced the connection strength of the joints.

2. With the help of the tread compound, the external upset tubing can be sealed. There is a space of 0.076mm between the rest and root of the thread.

When the thread is screwed up, this space will be filled with thread compound. When the tread compound is solidified, it will jam the space to realize the sealing effect.

3. Coupling of external upset tubing has a lightweight (Its minimum weight is 1.55kg and the maximum weight is 6.02kg). Customers can feel convenient to install and use it.

4. Our product has undergone manual thread inspection, the nondestructive coupling test, the surface paint spraying and other processes. Therefore, the reliable quality of the product and stability of the oil tube connection is ensured.
