ASC Engineered Solutions 310522404 – Frequently Asked Questions
1) What are the three port sizes on the ASC Engineered Solutions 310522404 black malleable iron tee?
It's a reducing tee with 1 inch on the run (both ends) and a 1/2 inch branch. All three openings are female pipe thread, so pipe or nipples thread into the fitting rather than over it. Handy when you need to pull a 1/2 inch takeoff off a 1 inch line without cutting in a bushing.
2) Is this tee approved for fire sprinkler piping?
It carries UL/FM approval, so it can be used on fire protection piping where the authority having jurisdiction requires listed fittings. It's black malleable iron, extra heavy class, with all-female NPT ports at 1 x 1/2 x 1.
3) Can I use a black malleable iron tee on a domestic water line?
No. Black malleable iron fittings are for gas, fire protection, steam, and non-potable service. The black finish has no corrosion protection against potable water, so use galvanized, brass, or copper on domestic water instead.
4) What does XH mean on a malleable iron tee, and when do I need it instead of standard weight?
XH is extra heavy, meaning thicker walls and a higher pressure rating than a standard (150) malleable fitting of the same size. Use it where the system pressure or mechanical loading exceeds what a standard-class fitting is rated for. The pressure class on this tee follows ASME B16.3, the same standard that sets its face-to-face dimensions, so it interchanges dimensionally with other B16.3 fittings of the same class.
5) What iron grade is this tee cast from?
The casting conforms to ASTM A-197, the specification for cupola malleable iron used in pressure-rated pipe fittings. That's the grade spec you cite on a submittal alongside the ASME B16.3 pressure and dimension requirements.
6) How much does the 1 x 1/2 x 1 extra heavy tee weigh for takeoff and freight?
1.36 lbs each. Worth counting if you're ordering a case quantity for a riser package, since extra heavy fittings run noticeably heavier than standard weight in the same size.
