Suggested Specification Guidelines:

Insulated Pipe Guides, Slides and Anchors (Continued)

1.3 Pre-Insulated Pipe Slides

A. - Shall allow a minimum axial movement of +/- 2 inches.

B. - Shall allow a system design maximum lateral movement of +/- 2 inches.

C. - Shall have a 360 insulation insert of Xonotlite calcium silicate with a minimum 450 PSI compressive strength, factory jacketed with a vapor barrier meeting ASTM E96-A and having a perm rating of 0.02, encased in a G-90 galvanized steel protection shield.

D. - Insulation insert and integral vapor barrier jacket shall extend a minimum of 1” beyond each end of the protection shield for all systems designed to operate below ambient air temperature.

E. - Select appropriate model from table or chart and submit specification/data sheet showing load ratings for pipe, type of service, and spacing for each application.

1.4 Pre-Insulated Pipe Anchors

A. - Shall be provided ready to be bolted or welded to a structural building component.

B. - Shall prevent vertical, lateral and axial movement of the pipe.

C. - Shall have 360 insulation inserts of Xonotlite calcium silicate having a minimum 900 PSI compressive strength for all pipe sizes. Anchors shall be of a length recommended by the manufacturer to meet the required design loads.

D. - Select proper model and submit table or chart showing load ratings for pipe, type of service, and spacing for each application or system.

E. - Insulated pipe anchors shall be used for vertical as well as horizontal pipe and on all piping systems where expansion, contraction and/or pipe movement is anticipated.

F. - All anchors must have anchor lugs field welded to the pipe. 'Friction anchors' are not permitted.

G. - All anchors must be installed in conjunction with manufactured expansion joints, bellows or loops and meet or exceed the expansion units' design loads.
