A compression apparatus (10) for compressing a tubular structure (12) to be formed into a hollow structure (20) such as a pipe comprises contact elements (60) arranged in two sets, (61, 62). The contact elements (60) are adapted to move along a compression section (41) in a coordinated sequence, whereby a portion (12a) of the tubular structure (12) within the compression section (41) is compressed between pairs (63) of opposed contact elements. The apparatus (10) includes registration means (110) for causing respective pairs (63) of opposed contact elements (60) to be maintained in registration with each other while moving along the compression section (41).

A resin composition and method for installing a pipe liner that allows the liner to be fully wet out with a resin and activator and stored for a period of up to six months prior to installation and curing. A method of lining a pipe with a delayed curing resin composition is also provided that includes fully wetting out a liner with a blended two part epoxy composition such that the liner can be transported in a wet out fashion, placed in a pipe to be lined and repositioned as needed without concern for the resin composition to begin curing.

A steam generator for use with a liner assembly for pipeline repair or reinforcement, includes: a water heater configured to heat water to generate steam; a water feed conduit configured to convey water to the water heater; an air heater configured to generate heated air; an air supply conduit configured to convey pressurized air to the air heater; a heated air supply conduit configured to convey heated air from the air heater to the water heater to yield a steam-air mixture; and an output conduit configured to convey the steam-air mixture from the water heater. An automated steam generator system including the steam generator is also described.

A method of installing a liner assembly for pipeline repair or reinforcement includes: pulling a prepared liner assembly into position in the pipeline, the liner assembly including a tubular liner wetted with a curable compound; introducing fluid into the inflatable bladder to bring the tubular liner into firm contact with an interior surface of the pipeline; flowing the fluid continuously through the bladder and discharging the fluid into the pipeline, while maintaining the liner assembly in an inflated condition; measuring a flow rate and a temperature of the fluid entering the bladder; calculating a time period sufficient for the tubular liner to cure based on: an amount of heat required for curing, based on dimensional information of the liner, and the measured flow rate and temperature of the fluid; and maintaining the liner assembly in an inflated condition for the time period sufficient for the tubular liner to cure.

Embodiments provide a lamination machine and lamination process for laminating a membrane to a three-dimensional (3D) target surface of an article, such as a footwear article, glove, clothing article, backpack, or other article. The lamination machine may include an inflatable former that is permeable to air. The inflatable former may have a shape that generally corresponds to a shape of the target surface. The membrane and target surface may be arranged on the former, with a heat-activated adhesive disposed between the membrane and the target surface. The lamination machine may further include a pump to pump heated compressed air into the former. The heated compressed air may inflate the former to press the membrane against the target surface and to activate the adhesive to bond the membrane to the target surface.

A method of installing a liner assembly for pipeline repair or reinforcement includes: pulling a prepared liner assembly into position in the pipeline, the liner assembly including an outer tubular liner and an inner inflatable bladder positioned longitudinally within the tubular liner, the tubular liner being wetted with a curable compound; introducing fluid into the inflatable bladder so that the inflatable bladder expands to bring the tubular liner into firm contact with an interior surface of the pipeline; flowing the fluid continuously through the bladder and discharging the fluid into the pipeline, while maintaining the liner assembly in an inflated condition for a time period sufficient for the tubular liner to cure; and deflating the inflatable bladder and retrieving at least a portion of the liner assembly from the pipeline.
