Abstract
An pneumatic plug for sealing a pipeline. The pneumatic plug includes a tubular member that extends in an axial direction from a first end to a second end. The tubular member includes a rubber layer and a fiber layer. The rubber layer extends from the first end to the second end of the tubular member. The fiber layer is disposed on a top surface of the rubber layer. The fiber layer includes a plurality of fibers that extend from the first end to the second end of the tubular member. Each of the plurality of fibers extend at an angle that is offset from the axial direction.
Claims22
A pneumatic plug for sealing a pipeline, the pneumatic plug comprising:
- a tubular member extending in an axial direction from a first end to a second end, the tubular member comprising:
- a rubber layer extending from the first end to the second end of the tubular member, and
- a fiber layer disposed on a top surface of the rubber layer, the fiber layer including a plurality of fibers extending from the first end to the second end of the tubular member, wherein each of the plurality of fibers extend at an angle that is offset from the axial direction.
A method for manufacturing a pneumatic plug, the method comprising:
- disposing a rubber layer about an outer surface of a mandrel, the rubber layer extending in an axial direction from a first end to a second end forming a tubular member;
- and
- disposing a fiber layer on a top surface of the rubber layer, the fiber layer including a plurality of fibers extending from the first end to the second end of the tubular member, wherein each of the plurality of fibers is disposed at an angle that is offset from the axial direction.
A system for manufacturing a pneumatic plug, the system comprising:
- a mandrel having an outer surface that extends from a first end to a second end spaced from the first end along a central axis, wherein each of the first end and the second end define a first curve and a second curve, respectively, wherein in cross section of the mandrel through the central axis the first curve and the second curve each define a parametric curve about a first transverse axis and a second transverse axis, respectively, each of the first and second transverse axes being substantially perpendicular to the central axis.
