api 5ct l80 13cr oil TUBING

As one of the greatest inventions of the last century, from the 1960s to the 1970s, the coiled tubing could not be successfully applied in deep wells because the material strength and straight weld strength of the coiled tubing at that time could not meet the requirements of repeated circulation and high axial load required for deep well operations. Combined with various comprehensive factors such as weld failure of coiled tubing, equipment failure and increasing downhole accidents at that time, this technology was not very promising by the oil and gas industry. Later, in the development of more than 40 years, with the improvement of the strength and performance of coiled tubing itself and the continuous improvement of the technology, the advent of coiled tubing operation TUBING COUPLING equipment and the development and matching of downhole operation tools, the application field of this technology continues to expand, and people gradually show its real charm Api Line Couplings.

Tubing is pipe used for the transportation of crude oil and natural gas from an oil or gas layer to the surface after drilling is complete.

It is made to withstand the pressure generated from the extraction process.
