Surface Finish: An Important Characteristic in Fluid System Components 


Maximize service life and reduce maintenance costs with the right surface finish

The surface finish of process vessels, piping, and related components significantly impacts performance, maintenance costs and service life. A poorly finished surface can increase friction, promote bacterial growth, and accelerate corrosion, leading to inefficiencies and higher operational costs. As industries like pharmaceuticals and biotechnology enforce stricter surface finish requirements, understanding and meeting these standards is critical.

The white paper, Surface Finish: An Important Characteristic in Fluid System Components, explores:

  • How surface finish affects fluid system performance, from pressure drops to contamination risks
  • The role of surface roughness in system efficiency and maintenance
  • Key industry standards, including ASME BPE-2009 and ISO 4287 that dictate compliance
  • Surface measurement techniques and finishing processes such as mechanical polishing and electropolishing.

Process and quality engineers will learn:

  • How to evaluate and quantify surface roughness for regulatory compliance
  • Best practices for achieving superior finishes to improve system longevity
  • Strategies to minimize contamination, improve cleanability, and enhance corrosion resistance.
