MECS® ZeCor®-Z Alloy Piping Systems for Sulfuric Acid Plants

MECS® ZeCor®-Z Alloy Piping Systems

Our ZeCor®-Z alloys have transformed the economics, safety and reliability of sulfuric acid piping systems. Our lightweight, smaller pipes deliver unprecedented corrosion resistance, in fully-welded standard and custom fabrications, boosting performance and lowering costs.

Piping systems rate as one of the top vulnerabilities of sulfuric acid plants. Traditional systems, made of iron, plastic-lined, or merchant-grade stainless steels, often require numerous flange connections. These connections introduce potential leakage points, creating serious safety and environmental risks, not to mention ongoing maintenance costs.

MECS® has revolutionized sulfuric acid piping systems with the introduction of ZeCor®-Z, our extremely corrosion-resistant engineered alloy. Exclusively from MECS®, ZeCor®-Z pipes deliver 10 times the corrosion resistance of cast iron piping systems. Typically, the corrosion rate for ZeCor®-Z is less than 1 mpy (0.025mm/yr) in drying and absorbing tower circuits, depending on concentrations and temperatures. What’s more, the lighter weight and fully welded design of ZeCor®-Z piping systems makes them easier and more cost-effective to install, field-modify, and maintain. The pipe can be pre-spooled and shipped directly to your facility, reducing installation time and costs.

High-Performance, Corrosion-Resistant MECS® ZeCor® Alloys

ZeCor®-Z piping systems require far fewer flange connections, which dramatically reduces acid leaks and greatly diminishes safety and environmental risks. ZeCor®-Z's high ductility also minimizes the risk of brittle failure. There is less erosion from velocity with ZeCor®-Z, compared to iron piping, so smaller piping diameters — available from stock or custom-sized to your project — can be used throughout your facility. Your system footprint shrinks, even as operations become more efficient, with cleaner acid thanks to a dramatic reduction in iron sulfates. The ultra-low corrosion rate and long life of ZeCor®-Z piping can improve your plant performance with maximum on-stream time, and reduce maintenance costs. What’s more, ZeCor®-Z can usually be installed for less than the cost of Teflon®-lined or Alloy 20 piping. Altogether, our ZeCor®-Z piping systems combine the best in process knowledge, materials technology, quality systems, and fabrication techniques to enhance the safety, reliability and value of your sulfuric acid plant.
