ABSTRACT:
A self propelled vehicle (14) has rollers (20, 22) supporting the vehicle for movement. A ring (44) is mounted for rotation and has rolls (54) of wrapping material (55) thereon for wrapping the pipeline (10). A plurality of discharge nozzles (82) spaced about the pipeline (10) forwardly of the rolls (54) of wrapping material (55) spray a liquid coating material in streams (86) impacting adjacent wrapped and unwrapped portions of the pipeline 10 as shown in FIG. 9. The wrapping material (55) is porous and the coating material permeates and saturates the wrapping material from both the inner and outer surfaces of the wrapping material (55). Fabric-type wipers (81) rearwardly of the rolls (54) of wrapping material (55) smooth and even the outer surface of the wrapping material and upon curing of the coating material, such as an epoxy resin, a hard outer protective liner or covering is formed including the wrapping material.
A separate embodiment in FIGS. 10-16 shows a stationary wrapping and coating machine (14A) for wrapping and coating separate pipe sections (10A) removably connected in end to end relation by a separate connector (13A) for moving through the machine (14A). An inner non-porous wrapping material (23A) is wrapped about the joint between the pipe sections (10A) before application of the wrapping and coating materials and is removed from the pipe sections (10A) after application of the wrapping and coating materials.
