ASC Engineered Solutions 311010003 – Frequently Asked Questions
1) Is the ASC Engineered Solutions 1-1/2 x 3/4 galvanized 90 degree elbow female threaded on both ends?
Both openings are FPT (female pipe thread), so it takes male threaded pipe or nipples on each side. The larger end is 1-1/2 inch and the smaller end is 3/4 inch, making it a reducing 90. Threads are cut to ASME B1.20.1, the standard NPT thread spec, so it mates with standard threaded steel pipe.
2) Can I use this galvanized malleable iron reducing elbow on a fire sprinkler line?
It carries a UL/FM listing, which is what an inspector looks for on sprinkler piping. It is standard (STD) pressure class malleable iron built to ASME B16.3 for both dimensions and pressure rating. Confirm the class called out on your drawing matches STD before installing.
3) Do I still need a bushing if I'm going from 1-1/2 inch pipe down to 3/4 inch?
No. This is a reducing 90, so the size change happens inside the fitting, 1-1/2 inch on one end and 3/4 inch on the other. That saves you a reducing bushing and one extra joint to seal, and it keeps the takeoff tighter than an elbow plus bushing stack.
4) Is this elbow suitable for outdoor or damp locations, or should I use black iron?
The galvanized finish is applied to ASTM A-153, the hot dip spec for threaded hardware, which is why galvanized malleable iron is the usual pick for wet, outdoor, or corrosive runs. Black malleable iron is the choice for interior dry gas and dry sprinkler service; for water lines and exposed piping, this galvanized version is the right one.
5) What material spec does this ASC malleable iron fitting meet, and will it pass a job spec calling for ASTM A197?
The casting is malleable iron to ASTM A-197, with dimensions and pressure rating to ASME B16.3 and NPT threads to ASME B1.20.1. That is the standard set most mechanical and plumbing specs cite for threaded malleable iron fittings, so a submittal calling for A197 is satisfied.
6) What is the part number and weight on the ASC 1-1/2 x 3/4 galvanized 90 reducing ell for my takeoff sheet?
Manufacturer part number 311010003, ASC Engineered Solutions. Each fitting weighs 0.85 lbs, which is what you want for figuring hanger spacing and freight on a bulk order.
