Patent ID: 7861743

Claim:
A method of lining a lumen of a conduit with a sacrificial lining system, comprising: providing a liner system having a liner portion including a perimeter wall continuous about a circumference of the liner portion, and a flange portion being positioned at and being continuously united to a proximal end of the liner portion, the distal end of the liner portion being free of any flange structure, the liner portion having an outer surface with a uniform diameter from the proximal end to the distal end of the liner portion, the liner portion having an inner surface with a uniform diameter from the proximal end to the distal end; inserting a distal end of the liner portion into the lumen of the conduit; detecting a degree of wear on an inner surface of the liner portion; changing an orientation of the liner portion in the conduit to present a changed wear surface; and adjusting a length of the liner portion to a length of the conduit while the liner portion is positioned in the lumen of the conduit; wherein changing the orientation includes rotating the liner portion about a longitudinal axis; wherein rotating the liner portion includes causing the rotation of the liner portion while the liner portion is positioned in the lumen of the conduit; wherein rotating the liner portion includes rotating the liner portion such that flow of a particulate material contacts a different area of an inner surface of the liner portion; wherein inserting the liner portion includes passing the distal end of the liner portion through a second end opening of a second end of the conduit so that the liner portion extends past the second end of the conduit; wherein adjusting the length includes shortening the length of the liner portion; and wherein adjusting the length includes severing a distal end section of the liner portion which protrudes out of a distal end of conduit from a proximal end section of the liner portion positioned in the lumen of the conduit.
