Deflected laser optics and an axicon cure resin liners from outside the pipe, cutting complexity, cost, and intensity loss.

Spring-actuated balls or rollers on a wedge cone grip pipe IDs securely, resist sand buildup, and retract easily for testing and maintenance.

An inflatable, light-permeable bladder centers the light train to deliver even UV curing of resin liners during pipeline repair.

A reduced-modulus sleeve expands first at bends, letting trapped air escape so the pipe liner fully contacts the wall without flow restriction.

Low-frequency pig tracking signals are converted into audible sound, making pipeline pig location more accurate and easier to detect.

Split repair sleeves use induction heating and retained backing strips to weld a fluid-tight pipe seal without cutting out damaged sections.

Preformed ribs and undercuts improve adhesive bonding on pipe connections, reducing site preparation, leakage, and renovation time.

Using the pipe itself as the filter housing cuts casing weight, cost, and installation complexity while maintaining pressure-resistant filtration.

An embedded hard core guides seal deformation so a gate valve seals orthogonal pipe walls with less insertion force and less leakage.

Moisture-activated foam encapsulates asbestos concrete pipe in place, allowing HDPE relining without excavation, dewatering, or hazardous disposal.
