Whoops, you are right. I should look in the code before shooting from the hip. "Corrosion Resistant" (3.8.1.2) versus "Corrosion Retardant"(3.8.1.3). With the ABF coating obviously being the latter. So... technically galvanized pipe falls under the definition of "Corrosion Retardant"???... but it

I think applying ABF pipe to that allowance is a step too far. ABF is a microbial coating to address MIC. I haven't heard anyone identifying it as a basic corrosion inhibitor. Also it has a finite life span. Roland On Oct 31, 2011, at 8:49 AM, Justin Reid wrote: Matt, I believe a pro

Matt, I believe a product such as Allied's ABF coated pipe would meet the intent as corrosion resistant therefore being an alternative to galvanized. Since galvanized pipe is starting to fall out of favor, this will probably be used more often to satisfy that particular code section. Justin Reid

In the 2007/2010 edition of NFPA 13, section 8.3.4.3 allows k 4.2 sprinkler heads to be used on dry systems where the piping is corrosion resistant or internally galvanized. Are there any options that people are aware of for corrosion resistance besides internally galvanized? (Copper being too
