Choosing the Underground Lifeline – A Technical and Economic Comparison Guide for Different Concrete Pipes

From a decision-maker’s perspective, this article builds a clear selection logic. Using comparison tables, it visually presents the core differences among ordinary reinforced concrete pipes, CTP, PCCP, and various fiber-reinforced concrete pipes regarding pressure rating, crack resistance mechanism, corrosion resistance, lifecycle cost, and typical application scenarios. It proposes four key questions for selection: What is the project pressure? How corrosive is the environment? How to balance budget and lifecycle? Are there special construction conditions? The aim is to assist engineers and owners in making the most economical and safest technical decisions.
