Dual-Component Polyurethane Spray Technology for Repairing Concrete Pipes: A Case Study
Publication: Journal of Pipeline Systems Engineering and Practice
Volume 15, Issue 4
Abstract
This study examines the feasibility and effectiveness of the sprayed-in-place pipe (SIPP) technology for concrete pipe repair, with a focus on a dual-component, high-strength spray lining material enhanced with an epoxy resin sealing layer. The research was conducted using a simulated experiment rig, tailored to specific environmental characteristics and the specifications of BONNA pipe, a type of precast reinforced concrete pressure pipe. This setup allowed for a detailed feasibility study of an automated spray process under simulated working conditions. The experimental process involved applying the lining material to concrete substrates, achieving a smooth, pinhole-free surface, with quality control managed using a high-voltage spark tester. The lining demonstrated exceptional impermeability, showing no penetration under 3 MPa water pressure, and maintained strong adhesive strength with the substrate, exceeding 6 MPa as indicated by substrate concrete failure during testing. Furthermore, the technique’s applicability in complex scenarios was tested, including automatic spraying inside 90° elbows, with lining thickness variations staying within acceptable limits. These findings suggest that the process is highly suitable for on-site pipeline conditions, offering a robust and reliable solution for enhancing the durability and integrity of pipeline infrastructures. This study provides practical engineering references for the SIPP repair method, demonstrating its potential as a significant advancement in pipeline repair and maintenance.
