The Importance of MIC Shield for Protecting Fire Sprinkler Pipe

Fire protection systems are the most critical systems of any building. From a protection standpoint, fire sprinkler pipe helps ensure that when the need arises, water will flow and spray from the system properly.

However, if the pipe is compromised in any way it’s not always possible for this to happen. And while there are several regulations that fire protection systems must meet or exceed to stay up to code, it doesn’t mean that the pipe isn’t susceptible to elements that can compromise its performance and increase corrosion. One element that has the ability to significantly cause corrosion of fire sprinkler pipe, and thus decreasing its effectiveness, is MIC.

Throughout this blog post, we’re going to review what MIC is, how it affects fire sprinkler pipe and how you can help prevent it from forming.

Let’s get started!

What is MIC?

MIC is the acronym used for microbiologically influenced corrosion, a problem for the long-term health of fire sprinkler and standard pipes. MIC is caused when unseen biological organisms called microbes gather to accelerate corrosion on the surface of alloys including copper, ductile iron, steel, and stainless steel.

CPVC Sprinkler Pipe: 31 Flavors of Risk

I’m sure there are some applications where installing CPVC sprinkler pipe makes sense.

Like, for instance, when the installer contractors won’t be eating lunch that day.

And when you’re certain no one will ever be painting, soldering or wiring anywhere near it. Or caulking. Or spraying for pests. Or using any number of oils, greases, solvents or foams in the CPVC’s vicinity — for years after you finish the job.

I’m sure applications like that exist…. I just can’t think of any.

In all seriousness (because this is a very serious topic), there’s a good chance that you may not be fully aware of just how many materials are incompatible with CPVC sprinkler pipe. Common products that contractors could possibly encounter— like caulk residue or oil on French Fries — could potentially come in contact with the CPVC and may cause the system to drip, crack or fail completely. Then you find yourself potentially at risk for potential property damage or even loss of life — and if, something like that happens, you and your company may be held liable.
