摘要： A process for producing a tube having a strength imparting tubular body and a tubular lining member covering and bonded to the inner surface of the tubular body comprises the steps of forming mandrel contact portions on a synthetic resin surface of a lining sheet in the form of a strip and noncontact portions in the surface distributedly among the contact portions, helically winding the lining sheet around a mandrel with the synthetic resin surface positioned inside and with the sheet lapping over itself, bonding the lap to the underlying portion of the wound sheet to form the lining member, and moving the tubular lining member axially of the mandrel in a direction to remove the member therefrom. The lining member formed around the mandrel is smoothly movable axially thereof by virtue of the presence of the contact and noncontact portions distributedly formed over the sheet resin surface.
