Why Do Sulfuric Acid Plants Prefer Titanium Heat Exchanger Tubes?

2025-07-08

In sulfuric acid production, heat exchangers are continuously exposed to high-temperature, high-concentration corrosive environments. Traditional materials like stainless steel and copper alloys often suffer rapid corrosion, leading to shortened service life and frequent maintenance shutdowns. In contrast, titanium—especially Grade 2 and Grade 12 tubes manufactured to ASTM B338 standard—has become the preferred material in many acid plants due to its exceptional corrosion resistance.

Titanium forms a dense and stable oxide film on its surface, which protects it against uniform corrosion, pitting, and stress corrosion cracking—even under harsh sulfuric acid conditions. These tubes can reliably operate for more than a decade, significantly reducing replacement frequency and maintenance costs, while enhancing overall operational stability and plant safety.

From the perspectives of long-term efficiency, maintenance reduction, and reliability, titanium heat exchanger tubes offer unparalleled advantages in the sulfuric acid processing industry.
