Abstract: Tubing everting apparatus, assemblies, and methods are disclosed herein. The tubing everting apparatus include a pressure chamber that defines an internal volume, a liner inlet port that is configured to receive a flexible tube liner into the internal volume, an inlet sealing structure that is configured to resist fluid flow therepast from the pressure chamber, and a liner outlet port that is configured to permit the flexible tube liner to extend from the internal volume. In some embodiments, the apparatus include a lubricator that is configured to apply a lubricant to the flexible tube liner. In some embodiments, the apparatus include a non-deflation valve that is configured to selectively transition between open and closed states. The assemblies include the apparatus and a cart that includes a lubricant reservoir. The methods include methods of operating the apparatus.

Abstract: Apparatus and a method for installing a tubular liner in a pipe, as in repair of underground sewer piping. A feeder is of flexible material, which may be similar to that of which the tubular liner is made, and is connected to an end of the tubular liner. The feeder includes a throat portion through which a quantity of inside-out tubular liner is drawn into the feeder by fluid pressure within the feeder and beyond the throat, and the tubular liner is thence urged by fluid pressure into the pipe where it is to be installed.

Abstract: A method and an apparatus for use in installing a liner in a conduit as part of a repair procedure, the apparatus including a sealing inlet port (106) for passage of the tubular liner (72) into an enclosed container (52) where an increased pressure is maintained to move the tubular liner into the conduit (179) and to evert it as it moves along the conduit. A clamp (80) holds one end of the liner to the outlet side of an everter box (50) supported on a frame (18) that may be mounted on a trailer hitch receptable. The sealing inlet port includes a pair of lips (112, 114) to press against the opposite sides of a flattened liner. Support members (148, 150) keep the lips from being forced back out toward the outside of the pressurized everter box and control friction between the lips and the liner. Inlet and outlet fittings are provided. The apparatus is portable on a trailer hitch receiver.

Abstract: An apparatus for use in installing a liner in a conduit as part of a repair procedure, including a sealing inlet port for passage of the tubular liner into an enclosed zone where an increased pressure is maintained to move the tubular liner into the conduit and to evert it as it moves along the conduit. A clamp holds one end of the liner to the outlet side of an everter box. The sealing inlet port includes a pair of lips to press against the opposite sides of a flattened liner. Support members may be used to keep the lips from being forced back out toward the outside of the pressurized everter box, and to control friction between the lips and the liner.

Abstract: A tubular member is arranged to be inserted in a hole drilled in adjacent monoliths astraddle a joint between the monoliths. The tubular member comprises an outer layer of material saturated with a resin capable of bonding to defining walls of the hole. An inner layer of fluid impermeable material is bonded to the outer layer of the tubular member. When installed in a drilled hole, the tube is placed with the resin saturated layer against and in bonding relation with the wall of the hole. A core portion may be placed in the tube to hold it in tight bonded engagement with the hole, such core portion comprising a flexible filler such as grout having an elasticity which when cured flexes with differential movements of adjacent monoliths. The tubular member has two or more barriers therein which prevent the saturating resin from washing away during installation.

Abstract: A tubular member is arranged to be inserted in a hole drilled in adjacent monoliths astraddle a joint between the monoliths. A tubular member comprises an outer layer of material saturated with a resin capable of bonding to defining walls of the hole. An inner layer of fluid impermeable material is bonded to the outer layer of tubular member. Prior to installation, the tubular member is non-inverted, having the resin saturated layer on the inside whereby upon being inverted into the hole by an inverting gas or fluid, the resin saturated layer turns outwardly for bonding to the walls of the hole. A core portion is placed in the tube to hold it in tight bonded engagement with the hole, such core portion comprising a grout having an elasticity which when cured flexes with differential movements of adjacent monoliths.
