Systems and methods for forming and deploying a pipe liner in a pipe main having a service lateral. The line is formed from three pieces of material. The piece of material forming the front top and of the main liner and the front of the lateral line has a cutout at the joint to reduce bunching, which can result in non-uniform liner thickness and may form obstructions at the joint.

A system and method for efficiently and safely installing a pipe liner is provided, as well as methods of using the same. The system and method for efficiently and safely installing, a pipe liner may provide an inverter configured to invert the pipe liner by introducing pressure into the pipe liner; provide a top roller; provide an assist system located between the inverter and the top roller, the assist system comprising: a main housing having a main housing top and a main housing bottom, and each of the main housing top and the main housing bottom having an opening; a first interior roller; a second interior roller; and a first motor; and feed the pipe liner onto the tarp roller, wherein the assist system feeds the pipe liner from the top roller to the inverter in an efficient and controller manner.

A liner tube is provided for repairing a main pipe line having a lateral pipe line connected thereto. The liner tube assembly includes a liner tube impregnated with a liquid material capable of curing and hardening. The liner tube includes a gasket or junction band positioned about the juncture of the pipe lines. The gasket or bands form a tight seal between the liner tube and the pipe line. Hydrophilic containment bands are positioned over a portion of the gasket or junction band and around the main liner on either side of the juncture of the pipe lines.

A liner tube for lining a pipe and pipe lining method. Liner material that includes a strength layer and felt backing layer forms the liner tube. The strength layer includes chopped strands of fiber oriented generally parallel to one another and distributed along the strength layer. The felt backing layer can be needle punched to the strength layer. Joining structure can connect opposite longitudinal edge margins of the liner material to form a tube shape. The liner tube is impregnated with a curable polymer, positioned in the pipe, and cured to form the liner. The liner stretches radially when it is positioned in the pipe. As the liner stretches, the strength layer remains fixed to the felt backing and the width of the overlapping edge margins does not decrease.

A CIPP liner feed roller for manipulating and feeding CIPP liner by pulling CIPP liner from a liner source and feeding it to where it is needed. The CIPP liner feed roller generally includes a main roller attached to a frame, a clamping roller attached to the frame and configured to be in parallel with the main roller, wherein the distance between the clamping roller and the main roller can be adjusted using one or more actuators, a drive unit comprising a motor configured to control the rotation of the main roller within the frame, a controller coupled to the drive unit and the one or more actuators, wherein the controller is configured to control the rotation of the main roller and the distance between the clamping roller and the main roller, and a support beam attached the frame and configured to be in parallel with the main roller.

A device for preparing a liner to be installed in a pipe. the device comprising a top part having rollers extending between top sides and having a top belt arranged on rollers. The device further comprises a bottom part having rollers extending between bottom sides and having a bottom belt arranged on the bottom rollers. One of the bottom rollers is a pulley roller driving the bottom belt when rotated. At least one roller of the top rollers is movably attached to the top sides, and at least one roller of the bottom rollers is movably attached to the bottom sides.

A system and method for efficiently and safely installing a pipe liner is provided, as well as methods of using the same. The system and method for efficiently and safely installing a pipe liner may provide an inverter configured to invert the pipe liner by introducing pressure into the pipe liner; provide a top roller; provide an assist system located between the inverter and the top roller, the assist system comprising: a main housing having a main housing top and a main housing bottom, and each of the main housing top and the main housing bottom having an opening; a first interior roller; a second interior roller; and a first motor; and feed the pipe liner onto the top roller, wherein the assist system feeds the pipe liner from the top roller to the inverter in an efficient and controller manner.

A liner for insertion into a pipe is described, said liner comprising a continuous tubular construction which is capable of eversion, the liner further comprising a deformation portion, a detachable connection between components of the liner and at least one load transfer member. A method of installing a liner in a pipe to be lined is also described.

Systems and methods for pipe lining systems and methods of use are described. Systems and methods may include a CIPP lateral liner that is inserted into a bladder forming a CIPP liner assembly that can be inserted into a pipe line for a pipe repair. CIPP liner assembly can include a membrane that produces superior results compared to the prior art. A backing ring may be used with these systems and methods.
