Product Overview

The PE100-RC Trenchless Rehabilitation Pipe is a high-performance polyethylene pipeline designed for non-excavation repair projects (Trenchless Technology).
It utilizes HDPE folding insertion (U-shaped or C-shaped liner) technology—where the folded PE pipe is pulled into the existing pipeline and then expanded using heat and pressure to form a tight-fit “pipe-in-pipe” lining structure.
This innovative solution restores the full functionality of aging pipelines while minimizing excavation, disruption, and environmental impact.

Key Material – PE100-RC

Manufactured from PE100-RC (Resistant to Crack) grade polyethylene, this pipe offers exceptional resistance to slow crack growth (SCG) and point load stress, ensuring superior long-term performance.
Compared with standard PE100 materials, PE100-RC delivers enhanced durability against scratches, indentation, and stress cracking, making it ideal for trenchless rehabilitation and complex underground conditions.

Technical Advantages

✅ No-Dig Installation (Trenchless Technology) – Significantly reduces surface disruption, construction time, and cost.
✅ High Crack Resistance – PE100-RC material resists slow crack growth under point loads and scratches.
✅ Restores Pipeline Integrity – Creates a new pressure-bearing “pipe within a pipe,” extending service life.
✅ Environmental Friendly – Minimal excavation, low waste generation, and reduced carbon footprint.
✅ Excellent Pressure Performance – Same pressure class as standard PE100, ensuring high reliability.
✅ Long Service Life – Enhanced mechanical strength and chemical resistance for over 50 years of use.
