A Diamond-Like Carbon Pipe Lining Resistant to High Temperature and Pressure Carbon Dioxide/Hydrogen Sulfide Environments

摘要

A method has been developed for creating diamond-like carbon (DLC) coatings on the interior surfaces of pipes. Newer formulations of DLC coatings have shown resistance to chemical attack in high temperature, high pressure autoclaves tests simulating sour production environments even when the coatings are deliberately mechanically damaged prior to testing. These coating have also been shown to be highly abrasion resistant in standard dry and wet abrasion tests. Thus, DLC coatings may significantly extend component life in abrasive hot sour applications in the oil and gas industry.
