ASC Engineered Solutions 311011001 – Frequently Asked Questions
1) Is the ASC Engineered Solutions 2-1/2 x 2 galvanized malleable iron 90 elbow threaded or does it need welding or solvent cement?
It's a threaded fitting, female on both ends. Both openings are FPT (female pipe thread) cut to ASME B1.20.1, so it screws onto male-threaded steel or iron pipe with pipe dope or PTFE tape. No welding, grooving, or soldering involved.
2) Can I use this galvanized malleable iron elbow on a fire sprinkler line?
Yes, this 2-1/2 x 2 reducing 90 is UL/FM rated, which is what an AHJ or fire marshal looks for on sprinkler piping. It's standard weight malleable iron with threaded ends, built to ASME B16.3 for dimensions and pressure rating.
3) Is this a Class 150 standard fitting or an extra-heavy Class 300?
Standard weight, which on malleable iron under ASME B16.3 is the Class 150 line. If your spec calls for extra heavy (Class 300) on a higher pressure service, this isn't the fitting for it.
4) Is the galvanizing on this ASC elbow hot dip or electroplated?
The finish is galvanized to ASTM A-153, which is the hot dip standard for galvanized coatings on iron and steel hardware. That's the coating spec normally called out for outdoor, damp, or fire protection service rather than a thin electroplated zinc.
5) Will a galvanized malleable iron fitting work on black steel pipe, or do I need to match?
Threads are ASME B1.20.1 NPT, so it will physically thread onto black steel pipe of the same size. Most specs still ask you to keep galvanized with galvanized and black with black on a given system, mainly to avoid mixing coatings in one wet line, so check what the drawing calls for before mixing them.
6) What material and grade is this fitting, for a submittal?
Malleable iron to ASTM A-197, galvanized per ASTM A-153, with dimensions and pressure rating per ASME B16.3 and threads per ASME B1.20.1. Manufacturer part number 311011001. That's the full spec string most submittals want on a threaded malleable iron fitting.
