Pipe-in-Pipe Liner (ASOE™)
Trenchless Rehabilitation for Pressure and Gravity Pipelines
PiPE-IN-PIPE LINER
The Capabilities
Kraft Energy & Engineering (KEEN) offers ASOE’s Pipe-in Liner™—an innovative, trenchless solution designed to rehabilitate aging or damaged pressure and gravity pipelines without the need for excavation. This method utilizes Fabric Reinforced Flexible Plastic Pipes (FRFPP) to restore pipeline integrity efficiently and cost-effectively.
PiPE-IN-PIPE LINER
Key Features
Trenchless Installation: Eliminates the need for digging, preserving existing infrastructure and reducing environmental impact.
Flexible Design: Capable of navigating 45° and 90° bends with a 5D radius, accommodating complex pipeline layouts.
High Pressure Resistance: Suitable for pipelines operating up to 4.2 MPa (600 psi), ensuring durability under demanding conditions.
Long Continuous Lengths: Allows for installation lengths up to 4,000 meters in a single pull, minimizing joints and potential leak points.
Minimal Surface Preparation: Requires only coarse cleaning before installation, streamlining the rehabilitation process.
Non-Structural Solution: The liner operates independently within the host pipe, maintaining its shape without relying on the existing pipe’s structural integrity
