3.3.3 Paint all black steel hangers with black enamel. Galvanized steel and copper clad hangers do
not require paint.
3.3.4 Prevent electrolysis in support of copper tubing by use of hangers and supports which are
copper plated, or by other recognized industry methods.
3.3.5 Provision for Movement:
3.3.5.1 Install hangers and supports to allow controlled movement of piping systems and to permit
freedom of movement between pipe anchors, and to facilitate action of expansion joints,
expansion loops, expansion bends and similar units.
3.3.5.2 Load Distribution: Install hangers and supports so that piping live and dead loading and
stresses from movement will not be transmitted to connected equipment.
3.3.5.3 Pipe Slopes: Install hangers and supports to provide indicated pipe slopes, and so that
maximum pipe deflections allowed by ANSI B31 are not exceeded.
3.3.6 Insulated Piping: Comply with the following installation requirements.
3.3.6.1 Shields: Where low-compressive-strength insulation or vapor barriers are indicated, install
coated protective shields.
3.3.6.2 Clamps: Attach clamps, including spacers (if any), to piping with clamps projecting through
insulation; do not exceed pipe stresses allowed by ANSI B31.
3.4 Installation of Anchors:
3.4.1 Install anchors at proper locations to prevent stresses from exceeding those permitted by ANSI
B31, and to prevent transfer of loading and stresses to connected equipment.
3.4.2 Fabricate and install anchors by welding steel shapes, plates and bars to piping and to
structure. Comply with ANSI B31 and with AWS standards.
3.4.3 Anchor Spacings: Where not otherwise indicated, install anchors at ends of principal piperuns,
at intermediate points in pipe-runs between expansion loops and elbows. Make
provisions for preset of anchors as required to accommodate both expansion and contraction
of piping.
3.4.4 Where expansion compensators are indicated, install anchors in accordance with expansion
unit manufacturer's written instructions to limit movement of piping and forces to maximums
recommended by manufacturer for each unit.
