Stainless steel is one of the most important material families used in process piping because its chromium-rich passive surface can provide strong resistance to many aqueous, chemical, atmospheric, and high-temperature environments. But “stainless steel” is not a single material. Austenitic, ferritic, martensitic, precipitation-hardening, duplex, and super duplex grades can have very different corrosion resistance, strength, … Read more
Pipe material selection for various components depends on the types of materials they transport. Various liquids that can be flammable, corrosive, explosive, volatile, reactive, and sometimes hazardous to human health are transported through pipelines, which is why selecting the proper pipe material is critical for safe industrial operations. Process Conditions for Pipe Material Selection Piping … Read more
