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
Pipe materials are chosen to contain a process fluid safely for the design life at the design pressure and temperature, while resisting corrosion, erosion and brittle fracture at the lowest cost. In process plants the main families are carbon steel, low-alloy (chrome-moly) steel, stainless steel, non-ferrous alloys and non-metallic materials. This page is the starting … Read more
