DragX is a novel surface treatment system for pipeline integrity, which utilizes nanocomposite technology to create a durable, low-friction internal surface that provides flow assurance, and prevents corrosion, deposition & adhesion. DragX can lower operations costs, maintenance costs and pipeline down-time.
DragX is an omniphobic, nanocomposite surface treatment that eliminates the need for costly inhibitors and injection of chemicals to assist in flow assurance. The nanotechnology create a smooth internal surface that actively prevents deposition & adhesion of materials like paraffin & black powder build-up.
DragX surface treatment is suitable for a wide range of pipe systems, including varying sizes, geometries, materials, transported fluids, etc.
DragX application minimizes down times and maximizes cost savings for all flow regimes and products. Benefits include increased efficiency & throughput, reduced pressure drop & power usage, mitigation of corrosion on internal pipe surfaces, reduction in adhesion of debris & paraffin, and reduced need for inspections, cleaning & maintenance. On heavily corroded lines, DragX could reduce the pressure drop losses by a factor of 2.

DragX uses advanced pigging solutions for applying the surface treatment uniformly on long, pipeline segments - utilizing a 72-hour pot-life combined with cure times between coats of just 30-90 minutes and full cure times in 12-24 hours.
In field trials, DragXTM could reduce pressure drop within a treated line by up to 25% when applied to a relatively clean, lightly corroded line. In comparison, traditional mechanical pigging and cleaning can only achieve improvement of 10% and this effect is only temporary.
The underlying surface-modification nanotechnology developed for DragX was created with support from the U.S. Department of Energy (DOE), U.S. National Energy Technology Laboratory (NETL), and the U.S. Environmental Protection Agency (EPA). DragX exhibits a pot-life of more than 70 hours, is effective at thicknesses of only 2mil, and cures in less than one hour. These attributes in the nanocomposite surface treatment make DragX an ideal solution for in-service pipelines, reducing costs and minimizing pipeline down time.
DragX has undergone successful testing by Test America, Inc. with support of the EPA for application to potable water lines and delivered successful, well-below containminant results for EPA Method 524.2: Volatile Organic Compounds (VOCs), EPA Method 525.2: Semi-Volatile Organic Compounds (SVOCs), and EPA Method 200.8: Lead/Copper.
Tests at Colorado School of Mines, in conjunction with the RPSEA program with the NETL, showed excellent asphaltene repellency and anti-hydrate plugging performance. Results on asphaltene repellency showed that DragX was 6x better than raw pipe and 5x better than an omniphobic alternative.
