Pipetite Grommet Achieves UL IP64 Rating

Pipetite Grommet Achieves UL IP64 Rating

Jun 13, 2013

When dust and moisture get in the wrong places they can cause production downtime and safety concerns. To lower these risks, Pipetite Grommet brings a higher level of protection to penetrations where air and electrical lines enter a cabinet or control panel. These small, yet effective, flexible silicone escutcheons now boast an IP64 rating, also known as a UL Rating. This means that the Pipetite Grommet is dust proof and splash proof from all directions. Its dust proof characteristics can greatly help...

Passivation vs. Electropolishing – Part 2

Jan 7, 2012

Is electropolishing actually necessary given that a 1.0 or greater Cr/Fe ratio can be achieved by passivation alone? The real question is, “Are we trying to only passivate the surface or are we trying to produce a corrosion resistant cleanable surface?” Chemical passivation will attain a chrome to iron ratio above 1.0 (Cr/Fe), without producing any measureable change in the finish characteristics of the surface. Electropolishing is designed to remove surface damage from mechanical polishing and produce a more cleanable, featureless, smooth surface finish. The need to electropolish a surface is dependent upon...

Is electropolishing actually necessary given that a 1.0 or greater Cr/Fe ratio can be achieved by passivation alone? The short answer? If a 1.0 Cr/Fe ratio is all you are trying to achieve, no it is not. Now for the long answer. First, the 1.0 or greater Cr/Fe ratio indicated in the ASME BPE standard is a minimal requirement. The best passive and corrosion-resistant surfaces will have a Cr/Fe ratio in excess of 1.5/1, again achievable by passivation alone. The pharmaceutical industry, in most cases, requires a 15-25Ra value typically achieved through a mechanical polishing procedure. It is this procedure that, in my opinion, causes many of the problems experienced today with the formation of the “gray residue” and Class 1 rouge that has plagued end users for years.

Whether for a gasket, valve seat, or O-ring, the choice of elastomer might seem like a minor decision, but it can have a major impact. If a seal material is a poor fit for the application, you could run into any number of problems, from swelling, to peeling or cracking. Needless to say, these could be a big deal in a sanitary process. But how do you decide what elastomer to use?
