Carbon Steel Piping Materials & ASTM Grades

Carbon steel is the fundamental material for industrial process piping due to its high tensile strength and versatility. Its performance depends heavily on the deoxidization manufacturing process—specifically, using fully “killed” steel to prevent porosity—and selecting the correct ASTM grade. While ASTM A106 (seamless) is mandated for high-temperature, high-pressure environments, ASTM A53 (welded or seamless) is … Read more

Pipe Material Types and Selection Guide

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
