3 These spacings do not prevail over calculated spacings and do not apply where there are concentrated loads between supports, such as flanges and valves.4 These spacings are based on a fixed-beam support with a bending stress not exceeding 16 MPa and insulated pipe with the appropiate contents, and the pitch of the line being such that sag of 2.5 mm between supports is incorporated in the design.

NOTES:1 Guides should be kept about 40 pipe diameters clear of corners or loops.2 Use of pipe guides on hot lines must be investigated to assure that no higher forces or stresses are transmitted to the piping system due to the location of the guide.3 For calculation of wind loads on pipes refer to AS/NZS 1170.2.
