Coiled tubing presents various advantages that revolutionize the conventional approach to oil pipe installation. Traditionally, the labor-intensive process of welding long rods of oil pipe end-to-end or to fittings proved slow and costly. Coiled tubing, however, offers a more efficient and cost-effective alternative, minimizing both time and labor expenses while ensuring a safer and maintenance-free installation.
The benefits of coiled tubing are as follows:
Improved corrosion resistance: Coiled tubing stands out for its superior corrosion resistance, thanks to the properties of stainless steel, duplex, and nickel alloys.
Increased reliability: Utilizing fewer mechanical fittings or welding in the coiled tubing process diminishes the likelihood of defects, such as leaks and other potential long-term failures, thereby enhancing overall reliability.
Reduced installation labor costs: Installing continuous lengths of pipe with coiled tubing proves more time-efficient and reliable compared to connecting multiple shorter lengths of pipe. This not only streamlines the installation process but also contributes to cost savings in labor.
