ASC Engineered Solutions 310501002 – Frequently Asked Questions
1) What thread and size is the ASC Engineered Solutions 1 inch black malleable iron 90 degree elbow?
Both ends are 1 inch FPT, meaning female NPT taper threads cut to ASME B1.20.1. It mates directly with 1 inch threaded black steel pipe nipples, no bushing or adapter needed, and it turns the run 90 degrees with the same size in and out.
2) What does XH mean on a malleable iron elbow, and is it different from a standard 150 fitting?
XH is extra heavy, the 300 class of malleable iron fitting. It uses thicker walls than a standard Class 150 fitting and carries a higher pressure rating under ASME B16.3, which is the same standard that governs its dimensions. If a drawing or a spec calls for Class 300 malleable iron, this is the fitting; a standard 150 black elbow will not meet it.
3) Is this 1 inch extra heavy black elbow UL listed and FM approved for a sprinkler system?
Yes, it carries UL/FM recognition, so it can go into fire protection piping where the authority having jurisdiction requires listed and approved fittings. It is a black finish malleable iron fitting made to ASTM A-197, the standard grade for cupola malleable iron fittings.
4) Can I use a black malleable iron 90 elbow on a potable water line?
No. Black malleable iron is for gas, fire sprinkler, compressed air, and non-potable service. For domestic water you want galvanized or a copper/brass or CPVC system instead, since black iron corrodes in potable water. The black finish here is the plain, uncoated version of the fitting.
5) Do I need thread sealant with this fitting, or does it seal on its own?
The threads are NPT taper per ASME B1.20.1, which seals on the thread flanks but still needs pipe dope or PTFE tape rated for the service. On gas work use a sealant approved for fuel gas. The joint is metal to metal, there is no gasket or O-ring in the fitting.
6) How much does the ASC 1 inch XH black malleable 90 elbow weigh?
1.15 lbs each. Worth knowing when you are hanging a long overhead run of extra heavy fittings, since the added wall thickness over Class 150 adds up across a hundred-fitting job for support spacing and freight.
7) What part number do I order for the ASC 1 inch extra heavy black 90 elbow?
The manufacturer part number is 310501002 from ASC Engineered Solutions. Give that number when matching an existing submittal so you get the extra heavy black version rather than a standard weight or galvanized elbow.
