Yandang CPVC Piping System Approved for Major Nuclear Power Plant (Conventional Island)

A newly constructed large-scale nuclear power plant selected the Yandang brand​ to supply critical water supply and drainage piping for its Conventional Island (CI)​ infrastructure. Nuclear projects demand the highest standards for material safety, fire resistance, and long-term durability, making the selection process exceptionally rigorous.

The Challenge​

Within a nuclear power plant's Conventional Island, the water supply and circulating systems operate under high temperatures and require absolute reliability. Standard materials often fail under thermal stress or pose fire hazards. The project demanded a solution with superior high-temperature resistance, inherent flame retardancy, and ultra-low ion leaching​ to ensure environmental compliance and operational safety.

Yandang Solution​

Yandang was approved to supply its Premium CPVC (Chlorinated Polyvinyl Chloride) Industrial Pipes, which passed rigorous nuclear-grade qualification tests:

• High-Temp Structural Integrity​ — Withstanding continuous hot water and steam conditions without softening.

• Nuclear Fire Safety​ — Inherently flame-retardant material, critical for power plant safety protocols.

• Ultra-Low Ion Leaching​ — Ensuring water purity and compliance with strict environmental discharge standards.

The system was installed in key non-safety-related auxiliary systems, including circulating water intake and plant process drainage.

Results & Impact

Since commissioning, the Yandang CPVC system has fully met the nuclear project’s core requirements for high safety, reliability, and longevity. This successful application demonstrates Yandang’s capability to serve the most demanding nuclear power infrastructure​ and heavy industry​ sectors, reinforcing our commitment to quality control at the highest level.
