INSTALLATION

9

Size, apply and install supports and anchors in compliance with manufacturers recommendations.

10


11

Install supports to provide for free
expansion of the piping system. Support all piping from the structure
12

using concrete inserts, beam clamps, ceiling plates, wall brackets, or floor stands. Fasten ceiling plates and
13

wall brackets securely to the structure and test to demonstrate the adequ
acy of the fastening.

14


15

Coordinate hanger and support installation to properly group piping of all trades.

16


17

Where piping can be conveniently grouped to allow the use of trapeze type supports, use standard structural
18

shapes or continuous insert channels for
the supporting steel. Where continuous insert channels are used,
19

pipe supporting devices made specifically for use with the channels may be substituted for the specified
20

supporting devices provided that similar types are used and all data is submitted for

prior approval.

21


22

Perform welding in accordance with standards of the American Welding Society.

HANGER AND SUPPORT SPACING

25


26

Use hangers with minimum vertical adjustment.

27


28

Where several pipes can be installed in parallel and at the same elevation, provide

multiple or trapeze
29

hangers.

30


31

Support riser piping independently of connected horizontal piping.
