| 主权项 | 1. A method of lining an inner surface of a tubular with a polymer, comprising: positioning a polymer injecting head within the tubular; forming an annular space between the injecting head and an inner surface of the tubular; injecting polymer through the injecting head into the annular space; moving the polymer injecting head longitudinally relative to the tubular while injecting polymer; and forming a helical shaped channel on an inner surface of the polymer. | ||
