Polymer Degradation In Industrial Services

Available for download

Once polymers are used reliably in a specific service, they become the material of choice due to their cost effectiveness. However, to choose and apply polymers dependably, one must consider their unique properties – they are different from the metals we use industrially. Through various examples of damaged and failed parts, this paper illustrates fundamental information about choosing, using, and keeping polymers in service. Polymers are subject to permeation, oxidation, aging, fatigue, installation damage, and other damage.

To use polymers industrially, one must be cognisant of how their properties differ from those of metals. For many industrial applications, the minimal degradation and long and dependable service of non-metallics make them essential. However, non-metallics have properties that fundamentally differ from those considered when selecting and using metals. This paper presents polymer characteristics that significantly impact their use at industrial sites. The information covers hoses, lined pipe, fiber-reinforced plastic (FRP) piping and tanks, o-rings, and pipelines with liners. The paper discusses characteristics such as permeation, oxidation, and viscoelasticity, along with examples of how these properties determined the service of failed parts.
