What this floor flange does

The Anvil 0310106000 is a 2-inch malleable iron floor flange rated Class 150. It connects flanged piping to a female NPT thread using four bolt holes and a 5 1/2-inch outside diameter. Plumbers and maintenance teams use it for drain and trap assemblies where pressure service is not required.

Behaviour under continuous service

The fitting is marked not for pressure service, so it is intended for gravity drainage or low-head applications rather than pressurised lines. Malleable iron provides mechanical strength for structural support and resistance to cracking under thermal cycling or vibration in permanent installations.

What it replaces and when to specify it

This flange replaces a worn or corroded drain-component flange in existing Class 150 piping systems. The jump is worth it when the installation demands a flanged-to-FNPT transition with four-bolt mounting and the system operates without internal pressure.

Questions about this item

Does the Class 150 malleable iron flange generate heat or noise during continuous drainage use?

The flange is a passive fitting with no moving parts, so it produces no noise or heat while in service.

What piping and fasteners must I already have to install this 2-inch floor flange?

You need a 2-inch FNPT pipe end and four bolts to match the flange bolt-hole pattern.

Will this Class 150 flange mate with older iron or steel pipe threads I am keeping?

Yes, the FNPT threads follow the standard taper so they engage existing iron or steel pipe of the same nominal size.
