ASC Engineered Solutions 310511001 – Frequently Asked Questions
1) What size and thread type are the ends on the ASC Engineered Solutions 1 inch black malleable iron 45 degree elbow?
Both ends are 1 inch female pipe thread (FPT), so it threads directly onto 1 inch male-threaded steel or iron pipe on each side. Threads are cut to ASME B1.20.1, the standard NPT taper thread spec, so it mates with any standard NPT nipple or threaded pipe end.
2) Is this 45 degree elbow UL listed and FM approved for fire sprinkler piping?
Yes, the 1 inch extra heavy black malleable iron 45 elbow carries UL/FM approval, which is what a sprinkler contractor needs for fittings in a fire protection system. Black malleable iron with NPT threads to ASME B1.20.1 is the usual make-up for threaded sprinkler branch lines.
3) What material spec do these ASC malleable iron fittings meet?
The castings are made to ASTM A-197, the specification for cupola malleable iron, and the fitting dimensions follow ASME B16.3. Those two callouts together are usually what a mechanical submittal or a government/institutional purchase spec is asking for on threaded malleable fittings.
4) When should I use a 45 degree elbow instead of a 90 on a pipe run?
A 45 gives you a gentler direction change and less flow resistance than a 90, and two of them let you offset a run around an obstruction while keeping the line parallel to where it started. Use a 90 when you need a square turn at a wall or riser. This ASC fitting is the 45 degree pattern in 1 inch, extra heavy, with FPT on both ends, so it drops into a threaded run wherever you would otherwise put a nipple and a bend.
5) Does this elbow reduce, or are both ends the same size?
Both openings are 1 inch, so it is a straight 45 with no size change. If the run has to step down through the turn, you need a reducing fitting or a separate bushing or reducer at one end.
6) What is the part number and weight on the ASC 1 inch XH black 45 elbow for my purchase order?
Order it as ASC Engineered Solutions part 310511001. Each fitting weighs about 1 lb, which is worth knowing if you are pricing freight on a full bundle of them for a job.
