ASC Engineered Solutions 310025200 – Frequently Asked Questions
1) Does the ASC 4 inch black malleable iron 45 degree elbow have female threads on both ends?
Both ends are 4 inch FPT, so it threads onto male-threaded pipe nipples or male adapters on each side. Threads cut to ASME B1.20.1 (NPT), which is what standard black steel pipe is threaded to, so it mates with ordinary 4 inch black pipe without an adapter.
2) Is this 4 inch malleable iron 45 elbow UL listed and FM approved for a fire sprinkler main?
Yes, it carries UL/FM recognition, which is what an AHJ looks for on threaded fittings in a wet or dry sprinkler system. It is a standard class black malleable iron fitting made to ASTM A-197 with dimensions and pressure rating per ASME B16.3.
3) Can I use a black malleable iron 45 degree elbow on a potable water line?
No. Black malleable iron fittings are for gas, fire protection, steam, air, and non-potable service. The black finish here is an uncoated mill finish that will rust in potable water service, so for domestic water use a galvanized, copper, or CPVC system instead.
4) Is this a Class 150 standard fitting or an extra heavy 45 elbow?
It is the standard (STD) class, not extra heavy. Standard malleable iron threaded fittings are the Class 150 line under ASME B16.3. If your drawing calls for Class 300 extra heavy, this is not that fitting.
