Overview

Factory made pre-insulated pipe guides, slides, anchors and supports shall be used on all insulated piping systems to protect and maintain the integrity of the insulated pipe system.

Pre-insulated pipe guides designed to support and control pipe expansion, contraction and lateral movement shall be used to protect expansion joints and vital equipment from shearing and lateral offset forces. Pre-insulated pipe guides shall be installed where indicated by the design engineer. The use of pre-insulated guides with expansion joints shall be controlled by the recommendation of the expansion joint manufacturer. At a minimum, three (3) guides on each side of the expansion joint shall be required.

Pre-insulated pipe slides; anchors and supports shall be used as required by the design engineer for all other pipe support points.

Pipe guide and slide plates must have one powder-coated or stainless steel surface opposing a heat-bonded PTFE pad to provide a low coefficient of friction over a broad range of temperatures. All components shall be manufactured in compliance with the Manufacturer's Standardization Society (MSS) SP-58 and SP-89.

Pre-insulated pipe guides, slides, anchors and supports shall be as manufactured by TRI-STATE INDUSTRIES, INC. or equal.

Pre-Insulated Pipe Guides

A. - Shall allow a minimum axial movement of 4 inches ( +/- 2).

B. - Shall allow a maximum vertical and lateral movement of +/- 1/8 inch.

C. - Shall have a 360° insulation insert of 450 PSI Xonotlite calcium silicate, factory jacketed with a vapor barrier meeting ASTM E96-A, perm rating of 0.02 and 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 temperatures.

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

F. - Insulated pipe guides may be selected for use in lieu of pipe rollers and Type 39 saddles.
