The Lightray LED UV System is a trenchless pipe rehabilitation technology used for cured-in-place pipe (CIPP) repairs. It uses ultraviolet (UV) light to cure a specially designed resin liner inside damaged pipes, restoring structural integrity without the need for full excavation. 

How It Works:

1. Liner Installation:
   A resin-impregnated liner is inserted into the damaged pipe (usually via access points like manholes or cleanouts).

2. Positioning the UV Light Train (Lightray):
   Once in place, the Lightray UV light train—a robotic system with high-powered LED UV lights—is pulled through the liner.

3. UV Curing:
   The LED lights activate the photo-initiated resin, curing the liner in place in a controlled, efficient manner. This solidifies the liner, creating a new, durable pipe within the old one.

4. Post-Cure Inspection:
   CCTV inspection is often used to confirm proper installation and curing.

Key Benefits:

• Fast Cure Time: UV curing can be completed in minutes rather than hours.

• No Hot Water or Steam: Unlike traditional CIPP, this method doesn’t need boilers or steam trucks.

• Low Energy Use: LED UV lights consume significantly less energy.

• Environmentally Friendly: Less odor, less mess, and fewer emissions.

• Long Lifespan: Cured liners typically last 50+ years.

Applications:

• Mainlines & Laterals (sewer, storm, and some water lines)

• Residential and Commercial Plumbing

• Municipal Infrastructure

• Pipe diameters typically range from 2 to 24 inches, depending on the specific system variant.
