ASC Engineered Solutions 311081004 – Frequently Asked Questions
1) Is this coupling a straight 1-1/2 x 1-1/2, or is it a reducer?
Straight. Size 1 and Size 2 are both 1-1/2 inch, so it joins two 1-1/2 inch pipes. If you need to step down to a smaller pipe, you want a reducing coupling, not this one.
2) What material spec does this malleable iron coupling meet, and will it pass a plan review?
The casting is malleable iron to ASTM A-197, with dimensions and pressure class to ASME B16.3, threads to ASME B1.20.1 and galvanizing to ASTM A-153. That is the full set of specs a submittal for threaded malleable iron fittings normally calls out.
3) Is a threaded malleable iron coupling the right way to join 1-1/2 inch pipe, or should I use a grooved coupling?
A threaded coupling like this one is a permanent, non-removable joint: both pipe ends screw in, so you can only take it apart by cutting or unthreading a long run. It suits branch work, repairs into existing threaded pipe, and hanger or structural nipple assemblies. If you need to disassemble the joint later, use a union instead of a coupling; if the pipe is already roll-grooved, a grooved coupling is the mating part, not this.
4) Does STD strength mean this coupling is only good for low pressure?
STD here is the standard pattern malleable iron class, and its pressure rating follows ASME B16.3, which sets the rating by size and class rather than a single number for all fittings. For higher pressure threaded service you would step up to an extra-heavy (XH) malleable iron or a forged steel fitting instead.
