ASC Engineered Solutions 310081203 – Frequently Asked Questions
1) Will a 2 inch black malleable iron coupling thread onto standard 2 inch black steel pipe?
Yes. The ASC Engineered Solutions 2 inch black malleable iron coupling has female pipe thread (FPT) on both ends, cut to ASME B1.20.1, which is the standard NPT thread used on schedule 40 black steel pipe. Both ends are 2 inch, so it joins two male-threaded 2 inch pipe ends in line.
2) Is this ASC 2 inch coupling acceptable for a fire sprinkler line?
It carries UL/FM approval, so it is acceptable where the sprinkler contractor's spec calls for UL Listed and FM Approved threaded fittings. It is standard (STD) class malleable iron to ASME B16.3, with pressure rating also per ASME B16.3.
3) Can I use a black malleable iron coupling on a domestic water line?
No. Black malleable iron is for non-potable service, typically natural gas, fire protection, compressed air, and low pressure steam lines. The black finish has no corrosion protection against water. For potable water use galvanized fittings or copper/PEX instead.
4) What is the difference between a standard and an extra heavy malleable iron coupling?
Class is the difference. This ASC coupling is standard (STD) class, which is the 150 class malleable iron fitting used on most gas, air, and fire protection piping. Extra heavy (300 class) fittings have thicker walls and a higher pressure rating for high pressure or steam service. If the drawing calls out 300 class, a standard coupling will not meet it.
5) What grade of malleable iron is this ASC coupling made from?
The casting is made to ASTM A-197, the standard for cupola malleable iron used in threaded pipe fittings. Dimensions and pressure rating both follow ASME B16.3, so it will match other B16.3 malleable fittings on the same run.
6) What is the ASC part number and weight for the 2 inch black coupling?
Model 310081203, weighing 1.45 lbs each. Handy when you are figuring freight or pipe hanger loading on a long threaded run.
