Dimensions are in pounds.

Notes: (a)- Hub flanges are to be used on pipe that has an OD equal to the nominal pipe size in the first column. (b)- *Pressure Ratings are from AWWA Table 3 Class D. (c)- Pressure rating at atmospheric temperature: sizes 4-12 in. inclusive, 175 psi; sizes larger than 12 in., 150 psi. (d)- These flanges have the same diameter and drilling as ANSI/ASME B16.1 class 125 cast-iron flanges. (e)- In sizes 24in. and smaller they also match up to ANSI/ASME B16.5 150-psi standard for steel flanges.

What Is Flange?

A flange is an external or internal ridge, or rim (lip), for strength, as the flange of an iron beam such as an I-beam or a T-beam; or for attachment to another object, as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera; or for a flange of a rail car or tram wheel. Thus flanged wheels are wheels with a flange on one side to keep the wheels from running off the rails. The term "flange" is also used for a kind of tool used to form flanges. Pipes with flanges can be assembled and disassembled easily. read more
