Yandang CPVC System Selected for Jinhe Biotech's Critical Fermentation Process

High-temperature, low-leaching CPVC piping ensures purity and stability for a leading global fermentation producer.

In a recent key infrastructure upgrade, Jinhe Biotech—a publicly listed leader in the fermentation industry—selected the Yandang brand to solve chronic piping challenges in its high-temperature biochemical production lines. The project demanded absolute reliability to prevent contamination and ensure uninterrupted output.

The Challenge

Jinhe Biotech’s production process involves continuous fermentation under high temperatures and mildly corrosive conditions. Standard piping materials suffered from thermal degradation​ and ion leaching​ (the migration of chemicals into the product stream), risking batch contamination and compromising food-grade safety standards. The plant required a solution that guaranteed purity, structural integrity, and decades of service life.

Yandang Solution​

Yandang engineered a Premium CPVC High-Temperature & Corrosion-Resistant System​ tailored for hygienic fermentation applications:

• Food-Grade Purity​ — Ultra-low ion leaching ensures the final product (e.g., Citric Acid) remains uncontaminated.

• High-Temp Structural Rigidity​ — Withstanding continuous hot water and steam without softening or deformation.

• Smooth Inner Surface​ — Preventing microbial adhesion and biofilm formation, simplifying cleaning (CIP).

The system was implemented across critical zones including process hot water loops, fermentation feed lines, and clean utility water supply.

Results & Impact

Since commissioning, the Yandang CPVC system has delivered outstanding resistance to heat and corrosion, fully complying with Jinhe Biotech’s stringent GMP and food safety standards. This partnership reinforces Yandang’s leadership in providing piping solutions for the fermentation, pharmaceutical, and fine biochemical industries, proving our capability where quality cannot be compromised.
