FIGURE 2.41 Typical pipe hanger types. (a) Pipe clamp; (b) adjustable saddle; (c) trapeze hanger;
(d) adjustable clevis hanger.

Vertical piping shall be supported as follows:

1. Cast iron pipe with caulked joints, each floor or 20-ft O.C.
2. Cast iron pipe with no-hub joints, each floor or 10-ft O.C.
3. Copper and SS tubing, 10-ft O.C.
4. Glass pipe 2 in and smaller, alternate floors or 20-ft O.C.
5. Glass pipe 2 1/2 in and larger, each floor or 10-ft O.C.
6. All other piping, alternate floors or 25-ft O.C.
7. A base support or hanger support at the offset of all piping from vertical to horizontal

Calculating Weight of Pipe and Contents

For systems with limited complexity that comply with conventional spacing, the hanger
assembly shall be selected to support the total weight of the piping. The procedure used to
calculate the total weight is as follows:
