ASC Engineered Solutions 311016604 – Frequently Asked Questions
1) Is this elbow acceptable for a fire sprinkler system?
It is UL/FM listed, so it can be used where the fire protection spec calls for a listed fitting. It is a standard pattern malleable iron fitting to ASME B16.3, galvanized per ASTM A-153, which is what most wet and dry sprinkler branch work specifies. Always confirm the size and pressure class against the sprinkler drawing.
2) Is this a standard class or extra heavy 150 pound malleable fitting?
Standard class. The strength rating is STD, and the pressure rating follows ASME B16.3, which is the class system for malleable iron threaded fittings. If your spec calls for extra heavy (Class 300) malleable, this standard fitting is not a substitute.
3) Will a galvanized malleable iron elbow hold up outdoors or in a damp mechanical room?
The hot dip galvanized coating is applied to ASTM A-153, the standard for zinc coating on iron hardware, which gives it far better corrosion resistance than a black malleable fitting in wet, humid, or exterior locations. The body is malleable iron to ASTM A-197. For potable water lines, check your local code, since many jurisdictions no longer allow galvanized steel piping on new domestic water.
4) Should I use a street elbow or a regular 90 with a nipple?
Use the street ell when you need to turn a corner right at a valve, pump, meter, or another fitting and there is no room for a close nipple. Its male end screws directly into the female port. A standard 90 with both ends female needs a nipple on each side, which adds two joints and more length. If you are joining two plain pipe ends in open space, the regular female by female 90 is the simpler choice.
