ASC Engineered Solutions 310054002 – Frequently Asked Questions
1) How do I read the 2-1/2 x 1-1/2 x 2 size on this ASC black malleable iron tee?
The three ports are different sizes: the two run ends are 2-1/2 inch and 2 inch, and the branch outlet is 1-1/2 inch. All three are female pipe thread (FPT), so you thread male-end pipe nipples into each. It's a reducing tee, so confirm which leg of your run takes the 2-1/2 and which takes the 2 before you make up the joints.
2) Is this ASC tee approved for a fire sprinkler system?
It carries UL/FM approval, which is what an AHJ looks for on fire protection piping. It is a Class 150 standard pattern malleable iron threaded fitting built to ASME B16.3, the usual choice for threaded sprinkler branch lines and risers.
3) Black malleable iron versus galvanized tee: which one do I need?
This one is the black finish. Black malleable iron is the standard for dry gas piping, fire sprinkler systems, and closed-loop hydronic heating. Use galvanized instead on wet services exposed to moisture or on potable water systems where code calls for it. Same ASME B16.3 dimensions either way, so the two are physically interchangeable.
4) Is this the standard pattern or extra heavy tee?
Standard pattern, which is Class 150 malleable iron under ASME B16.3. If your spec drawing calls for extra heavy (Class 300) at that size, this is not the fitting, since the Class 300 body is thicker and the pressure rating is higher.
5) Does this reducing tee meet ASTM A197 for a submittal package?
Yes. The casting is ASTM A-197 cupola malleable iron, with dimensions and pressure class to ASME B16.3 and threads to ASME B1.20.1. Those three specs plus the UL/FM approval are typically what a mechanical submittal on threaded black iron piping asks for.
6) How much does the 2-1/2 x 1-1/2 x 2 black iron tee weigh for hanger spacing?
The fitting weighs 3.43 lbs dry. Add that to the filled pipe weight when you size the hanger nearest the branch, since a reducing tee of this size usually wants support close by rather than relying on the run.
7) Can I use this tee on a compressed air or natural gas line?
Threaded black malleable iron of this type is commonly run on natural gas and shop compressed air. It's a Class 150 standard pattern body to ASME B16.3 with NPT threads, so joints are made up with a sealant rated for the service, gas-rated dope on fuel gas. Check the local gas code for your jurisdiction on threaded fitting use.
8) What is the manufacturer part number for this ASC tee?
ASC Engineered Solutions part number 310054002, the 2-1/2 x 1-1/2 x 2 black malleable iron reducing tee. That's the number to quote when matching it against other fittings on the same order.
