Anybody got an MSDS for this pipe? What exactly are these "chemical components of the anti-microbial coating" and are they harmful to pipefitters?
BTW some of y'all might be interested in my new project. The new Fire Station #1 in Downtown Orlando. It's a big one! http://www.cityoforlando.net/fire/Firehouse1%20renderings.htm ----- Original Message ----- From: "Terri Leyton" <[email protected]> To: <[email protected]> Sent: Tuesday, May 12, 2009 5:10 PM Subject: Tyco Update on Allied ABFII - Steel Coated Pipe and CPVC > Tyco Update on Allied ABF(r) > Steel Coated Pipe and CPVC > > > > The following notice has been issued by Tyco Fire Suppression & Building > Products regarding CPVC compatibility. > > "Since its introduction in 2004, Allied Tube & Conduit's ABF(r) II > anti-microbial steel sprinkler pipe has been installed and successfully > maintained in millions of feet of steel-CPVC applications.

Unusually high amounts of mechanical stress create an > environment that makes CPVC pipe and fittings more susceptible to ESC. > For example, some approved hangers have been found to put an excessive > mechanical stress on the pipe.

As a conservative approach > while the investigation continues, Tyco recommends that ABF II coated > steel pipe not be used in new systems containing CPVC. For these > applications, Allied will continue to make uncoated steel pipe > available. ABF II coated steel pipe should still be used in all-steel > systems, where it provides industry-leading anti-microbial protection. > > The overwhelming majority of installations of ABF II coated steel pipe > with CPVC pipe and fittings have provided reliable service without > incident for many years.
