Suggested Specification Guidelines:

Insulated Pipe Guides, Slides and Anchors

Mechanical Section 15
Anchors & Supports: 15040/15140

1.1 General

    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 supports, slides and anchors 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 Manufacturers Standardization Society (MSS) SP-58 and SP-89.

    Pre-insulated pipe supports, guides, slides and anchors shall be as manufactured by  Value Engineered Products, Inc. or equal.

1.2 Pre-Insulated Pipe Guides

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

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

    C. - Shall have a 360 insulation insert of Xonotlite calcium silicate having a minimum 450 PSI compressive strength, factory jacketed with a vapor barrier meeting ASTM E96-A, and having a perm rating no greater than 0.02. Inserts shall be encased in a G-90 galvanized or stainless steel protection shield.

    D. - Insulation inserts 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 proper model from table or chart and submit showing load ratings for pipe, type of 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.
