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.

In sulfuric acid processing, equipment reliability and material durability are essential to maintaining consistent plant operation. One of the most frequent causes of unplanned downtime is corrosion failure in heat exchangers, where traditional materials like stainless steel and copper alloys often degrade rapidly under harsh acidic conditions. Titanium heat exchanger tubes, particularly those manufactured to ASTM B338 standards, have proven to be a highly effective solution for extending operational life and reducing maintenance interruptions.   Titanium Grade 2 and Grade 12 are commonly used in sulfuric acid applications due to their outstanding resistance to corrosion, even at elevated temperatures and concentrations. Unlike steel, titanium forms a stable, protective oxide film on its surface, which significantly reduces the risk of uniform corrosion, pitting, and stress corrosion cracking. This property makes titanium tubing ideal for heat exchangers in acid plants where performance reliability is critical.   Jiangsu Hongbao Group produces a wide range of titanium heat exchanger tubes with outer diameters from 6mm to 60mm, wall thickness from 0.5mm to 2.5mm, and lengths up to 18 meters.
