An expandable anchor/seal is pushed up a ramp until making contact with the surrounding tubular as or after the anchor/seal contacts the same tubular. The setting sleeve is made from high yield steel that has a weakened leading end to reduce the force required to push the leading end and the anchor/seal and an outer surface treatment at a leading end that engages or penetrates the wall of the surrounding tubular. Preferably a plurality of fingers are formed with axially oriented slots starting from a leading end allowing fingers to flex as they ride up the ramp on the mandrel for setting the anchor/seal and locking that set with the setting sleeve exterior surface configuration that can abut or penetrate the surrounding tubular.

Travel stop for expansion tool to limit stress on a surrounding tubular

Self-locking expandable seal activator

Expandable seal with adjacent radial travel stop

An expandable seal has at least one travel stop designed to engage the surrounding tubular to limit expansion of the ring shape of the seal and in so doing limit the stress of circumferential ribs that extend from the ring base shape as they engage the surrounding tubular. The travel stop can be a solid ring or segments and can have a rounded outer surface designed to engage the surrounding tubular in a flush relationship. Alternatively the outer surface can also have hardened particles for a bite into the wall of the surrounding tubular before the blunt portions of the travel stop come into contact with the inside wall of the surrounding tubular.

Expansion limiter for expandable seal

A wiping device including a resilient body having a wiping surface. A support member is convertible between a first shape defined by a first center line of the support member and a second shape defined by a second center line of the support member. The support member is disposed relative to the resilient body to enable the resilient body to take a first set of dimensions when the support member is in the first shape and a second set of dimensions when the support member is in the second shape. A method of using a wiping device is also included.
