The Edmeston SX® system comprises equipment for the absorption stage of a sulfuric acid plant, manufactured using Edmeston SX® our proprietary acid-resistant stainless steel with excellent corrosion resistance over a wide concentration range at high temperatures. It has significant advantages over other alloys and traditional materials like cast iron, including superior equipment lifetime, low maintenance requirements, and ease of fabrication.
Excellent corrosion resistance over a wide concentration range
Superior equipment lifespan and minimal maintenance
Clean acid-free from corrosion products
Lightweight speeds up installation and reduces the need for foundation work
Edmeston SX® sulfuric acid steel is fully austenitic stainless steel material and particularly suitable for use in the following applications:
When exposed to sulfuric acid, the material forms a very strong passive surface layer of silicon oxide that protects it against corrosion. Under the normal plant operating conditions, the steel has excellent corrosion resistance in both static and dynamic conditions (See iso-corrosion diagram, Figure 1).Through its 30-year history, it has also proven capable of handling periods of upset conditions.
