Dear Sirs.

Good day.

 we (Jordan Petroleum Refinery Co.) intend to install an automatic fire fighting system ,according to NFPA 11; on two gasoline tanks  by contractor who offered us to use (UL listed) grooved pipe fittings (made from ductile iron to ASTM A536 Grade 65-45-12) in order to reduce the installation time and to avoid welding works at the project site.

Since we have not dealt with similar fittings before, we kindly asked whether these fittings are suitable to be used in construction of the fire fighting network for the mentioned tanks , noting that the fire fighting network will be outdoor, above ground and will pass across the tanks dike.

your prompt response is highly appreciated.
