High-Performance Polymers: The Gap Between Need and Science
In many engineering sectors, application environments for polymer-based materials are expanding into ever higher temperatures, differential pressures and increased corrosive chemical attack.
#materials
Do I need to be concerned about galvanic corrosion when selecting valve materials?
A: This is a good question, and the answer should begin with discussing exactly what is meant by galvanic corrosion.

The Expanding Reach of Plastic Valves
Although plastic valves are sometimes seen as a specialty product – a top choice of those who make or design plastic piping products for industrial systems or who must have ultra-clean equipment in place – assuming these valves don’t have many general uses is short-sighted.
