Hangers and Supports
Provide pipe hangers and supports conforming to MSS SP-58, MSS SP-69, and
ASME B31.1, except as specified or indicated otherwise. Hangers for high
pressure air lines shall be rigid or braced and sufficiently strong to
prevent "whipping" of a pipe if a break occurs while the line is under
pressure. Furnish zinc plated pipe hangers and supports except for copper
plated inserts for copper piping. Provide tubing supports of U-shaped
steel bolts and nuts firmly secured to adequately support structures such
as walls, columns, floors, or brackets. Clips shall fit closely around
piping but shall have sufficient clearance to permit longitudinal movement
of piping during normal expansion and contraction. Provide supports at
valves, fittings, branch lines, outlets, changes in direction, equipment,
and accessories.
