South-to-North Water Transfer Project
Completed in 2010, this key water conservancy project adopts professional heavy-duty anti-corrosion coating for PCCP pipeline external protection, ensuring long-term stable water transmission operation.
Project Overview
Project Site: China
Construction Year: 2010
Applied Coating: Industrial Heavy-Duty Anti-Corrosion Coating System
Construction Scope: Professional anti-corrosion protection for PCCP pipelines of the South-to-North Water Transfer Project
Industry Challenges
The South-to-North Water Transfer Project belongs to a large-scale national water conservancy infrastructure, with massive PCCP pipelines laid underground for a long time. Buried pipelines are constantly eroded by soil moisture, groundwater, microbial corrosion and soil chemical substances. Traditional ordinary coatings are prone to blistering, peeling and corrosion failure under long-term buried conditions. Pipeline corrosion damage will affect the stability of water transmission, cause pipeline leakage, and bring huge hidden dangers to the long-term operation of key water conservancy projects.
Customized Anti-Corrosion Solution
Aiming at the harsh buried environment and long-service-life operation requirements of water conservancy pipelines, we applied a professional heavy-duty anti-corrosion coating system for full external protection of PCCP pipelines. The coating possesses excellent soil corrosion resistance, waterproof permeability and ultra-high substrate adhesion. It forms a dense and stable protective barrier on the outer wall of PCCP pipelines, effectively isolating groundwater, humid soil and corrosive impurities, and solving the common corrosion problems of long-term buried water conservancy pipelines.
Project Operation Results
After the completion of anti-corrosion construction, the PCCP pipelines of the South-to-North Water Transfer Project maintain stable protective performance for a long time. The heavy-duty coating effectively resists underground complex corrosion, avoids pipeline leakage and structural damage caused by corrosion, reduces long-term operation and maintenance costs, and provides solid and reliable anti-corrosion guarantee for the safe and continuous operation of national key water conservancy transmission projects.
