What escutcheon size for 1 3/4" OD pipe? IPS confusion abounds
Help clear my confusion on the size of steam riser pipe escutcheon I need to order for risers measuring 1 3/4" OD. I'm not clear on the difference between IPS and nominal sizing. For instance, an amazon listing shows the following:
Floor and Ceiling Plate Split Flange, Fits 1-1/2 Inch IPS Galvanized Pipe or 2 Inch Copper Pipe.
What do I look for in product descriptions that will confirm that the flange escutcheon will be a nice, very close fit to the 1 3/4" OD of my steam risers?

for 1 1/4", 1 1/2" and 2" the OD is "about" a 1/4" larger than the nominal size. The nominal size is "about" the inside diameter. There are plenty of charts you can download
Order 1-1/4 and 1-1/2 from amazon and return the one(s) you don't use. Also, check out Supplyhouse.com They have a liberal return policy. (not a Democratic Liberal... Just Liberal the way we used to mean it)
