Application And Usage
ZeCor-Z alloy has changed the economy, safety, and reliability of sulfuric acid pipeline systems. The unique corrosion resistance of ZeCor alloy ensures that our lightweight and smaller pipelines not only provide unprecedented corrosion resistance in fully welded standards and customized manufacturing, but also improve performance and reduce costs. They can be installed quickly and cost-effectively to upgrade or repair existing sulfuric acid pipeline systems.
Based on specific concentrations and temperatures, the corrosion rate of ZeCor-Z is less than 1 mpy (0.025mm/yr) in typical drying and absorption tower circuits. The corrosion resistant ZeCor-Z alloy pipeline system has many advantages in maintenance, reliability, safety, ease of installation, and the ability to provide inventory or custom size pipeline sizes based on your project. The ZeCor-Z alloy pipeline system integrates process knowledge, material technology, quality system, and manufacturing technology. These practical advantages translate into the actual economic benefits of acid plant owners and operators.
