Coiled Tubing
Coiled Tubing
Coiled tubing is a jointless tubing formed by welding several sections of flexible tubing with a length of more than 100 meters through butt welding or inclined welding. The length of coiled tubing is generally up to several hundred meters to several kilometers. It can be wound on a reel and used for specific downhole operations such as workover, drilling, perforation, stimulation, well completion, and logging. For applications in acidic environments, our company has developed high-chromium corrosion-resistant alloy coiled tubing and titanium alloy coiled tubing.
