3.1

band (loop) hanger

type of pipe hanger where the distance from the structure to the pipe is adjustable and usually utilizes a metallic strip looped around the pipe for support of a load

Note 1 to entry: See Figure 1 j).

3.1.1

adjustable swivel band (loop) hanger

type of pipe hanger that is intended to accommodate support of piping at various directions in the same plane

Note 1 to entry: See Figure 1 e).

3.2

bracket

cantilever-type pipe hanger that is attached directly to a vertical surface of the building structure

Note 1 to entry: See Figure 1 l).

3.3

building attachment component

support fixing

pipe hanger component set into the wall, such as driven fastener, expansion anchor, undercut anchor, or cast-in insert, intended to support the pipe hanger

3.4

cast-in insert

type of building attachment component cast into the concrete at the time of pouring

Note 1 to entry: See Figure 1 m).

Note 2 to entry: Cast-in inserts can be channels, which take special threaded bolts, or internally threaded sockets, which accept conventional bolts or rods.

3.5

ceiling flange

type of building attachment component pipe hanger that is attached directly to an overhead surface of a building structure

Note 1 to entry: See Figure 1 k).

3.6

beam clamp

type of building attachment that is rigidly attached to both edges of the bottom flange of a structural member

Note 1 to entry: See Figure 1 a).

3.7

C-clamp

building attachment component that grips a flange by means of a jaw and setscrew combination

Note 1 to entry: See Figure 1 q).

3.8

riser clamp

pipe attachment component intended to support vertical piping (risers) at various levels

Note 1 to entry: See Figure 1 b).

3.9

top/bottom clamp

building attachment intended to rigidly grip one edge of a top or bottom flange of a steel structural member

Note 1 to entry: See Figure 1 d).

3.10

clevis hanger

type of split-ring pipe-attachment component

Note 1 to entry: See Figure 1 i).

3.11

clip

pipe-attachment component, usually a one piece and nonadjustable"U" shaped device that partially embraces a pipe intended to be attached directly to a building structure

Note 1 to entry: See Figure 1 c).

3.12

coupler

threaded rod coupling

threaded element used to connect the building attachment component (support fixing) to the rod

Note 1 to entry: See Figure 1 p).

Note 2 to entry: Couplers can have male or female threads (usually female) and can be the same thread throughout or two different thread diameters to link fixings and rods of different sizes (increaser coupler).

3.13

driven fastener

type of building attachment component driven into solid concrete or structural steelwork by means of a special tool, usually powder actuated, and can have female or, usually, male thread linked to the rod by means of a coupler

3.14

expansion anchor

type of building attachment component set into the concrete ceiling or wall of the building structure in self-drilled or pre-drilled cylindrical holes

Note 1 to entry: See Figure 1 n) and Figure 1 o).

Note 2 to entry: Ceiling fixings are usually “deformation-controlled” internally threaded socket anchors, which are expanded by driving an expander plug to the base of the shell or by driving the shell over the expander plug.

Note 3 to entry: Fixings for walls can be socket anchors or can be “torque-controlled” anchors, either through-bolts (where an expander clip is expanded by the tightening of the bolt) or sleeve anchors (where the sleeve is expanded by the tightening of the bolt).

3.15

pipe hanger

assembly of components used singly or in combination with other assemblies for supporting gravity loads of a piping system

Note 1 to entry: A pipe hanger can comprise a building attachment component (support fixing), coupler, rod or equivalent and pipe attachment component as shown in Figure 2, or a simple bracket and building attachment component (support fixing) as indicated in Figure 3.

3.16

non-heat sensitive material

material whose measured tensile strength at (540 ± 10) °C is at least 90 % of the value measured at (20 ± 5) °C

3.17

pipe attachment component

pipe hanger component that is attached directly to the pipe

Note 1 to entry: See Figures 2 and 3.

3.18

retaining strap

building attachment component, usually made from steel strip, intended for use in combination with a beam clamp, C-clamp or a top/bottom clamp to hold the clamp in place on the beam

Note 1 to entry: See Figure 1 q).

3.19

solid ring

pipe hanger that completely encircles a pipe without a positive gripping action that has to be slipped onto the end of the pipe and cannot be opened in any way for attachment to the pipe after the piping is fabricated

Note 1 to entry: See Figure 1 f).

3.19.1

split ring

pipe hanger that completely encircles a pipe without a positive gripping action that can be opened in some way to allow it to be installed on the pipe after the pipeline is fabricated

Note 1 to entry: See Figure 1 g).

3.19.2

swivel ring

solid or split ring pipe hanger, equipped with a top swivel allowing the pipe hanger to be connected to a rod after it has been installed onto the pipe

Note 1 to entry: See Figure 1 f).

3.20

undercut anchor

type of building attachment component installed in a concrete ceiling or wall of the building structure in self-drilled or pre‑drilled undercut holes

Note 1 to entry: The setting of the anchor, usually by hammering a sleeve over an outwardly tapered element, forces the sleeve out into the undercut shape forming a mechanical interlock with the base material. These anchors are intended for tension zones of concrete, i.e. cracked concrete.

3.21

welded studs

type of building attachment, usually fabricated from threaded material equal to the rod size that is intended to be welded to the steel building structure
