Three key factors for flange selection in industrial piping systems
In industrial piping system design, flange selection directly impacts project safety and cost-effectiveness. As a core component of pipe connections, the material, pressure rating, and sealing performance of a flange are the three key factors in its selection. This article will provide an in-depth analysis of how to choose the most suitable flange solution based on operational requirements, helping engineers avoid common selection pitfalls. Steel pipe flanges used in industrial piping system installation I. Material Selection: The Core Factor Determining Flange's Corrosion Resistance and Service Life The material for industrial-grade flanges needs to be comprehensively evaluated based on the characteristics of the medium, temperature, and environment. Carbon steel flanges (such as ASTM A105) are suitable for conventional water, oil, and steam systems, offering excellent cost-effectiveness; while 304/316 stainless steel flanges are designed for acidic, alkaline, or high-salinity...
