ASTM A213 Nickel Alloy 625/UNS N06625 Welded Coiled Tubing for Oil Industry


MTSCO has been supplying coiled tubing for the international geothermal, heat exchanger, shipbuilding, oil and gas industries for more than 10 years. In recent years, we have made breakthroughs in the fields of coiled tubing, downhole control lines and chemical injection control lines. We mainly produces welded/seamless coiled tubing, single/multi-core control line, capillary tube and other coiled tubing. The main materials are stainless steel, duplex steel and nickel alloy. The length can be more than 33000 fts/coil. The size, length, pressure and packaging method can be customized to ensure equipment quality and reduce maintenance costs.

The benefits of coiled tubing are as follows:

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.
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.
