(Practice)Standard Practice for Installation of Aluminum and Stainless Steel Jacketing over Thermal Insulation on Pipe and Rigid Tubing
Standard Practice for Installation of Aluminum and Stainless Steel Jacketing over Thermal Insulation on Pipe and Rigid Tubing
SIGNIFICANCE AND USE
5.1 This practice applies to materials manufactured in accordance with Specification C1729 (aluminum jacketing) or Specification C1767 (stainless steel jacketing). This standard is intended to provide a basic practice for installing these types of materials. Refer to Specifications C1729 and C1767 for information on the differences between aluminum and stainless steel jacketing and where each is considered for use.
5.2 This practice is not intended to cover all aspects associated with installation for all applications, including factory and field fabricated pipe fitting covers.
Note 1: Consult the National Commercial & Industrial Insulation Standards (MICA), Guide C1696, the product manufacturer, and/or project specifications for additional recommendations.
5.3 Metal jacketing is typically used on insulated piping located outdoors, including, but not limited to, process areas and rooftops. Metal jacketing is used indoors where greater resistance to physical damage is required, for appearance, for improved fire performance, or as otherwise preferred. Metal jacketing used outdoors serves the same functions as indoors and also protects the insulation system from weather.
5.4 Metal jacketing is used over all types of pipe insulation materials.
SCOPE
1.1 This practice covers recommended installation techniques for aluminum and stainless steel jacketing for thermal and acoustic pipe insulation operating at either above or below ambient temperatures and in both indoor and outdoor locations. This practice applies to materials manufactured in accordance with Specification C1729 (aluminum jacketing) or Specification C1767 (stainless steel jacketing). It does not address insulation jacketing made from other materials such as mastics, fiber-reinforced plastic, laminate jacketing, PVC, or rubberized or modified asphalt jacketing, nor does it cover the details of thermal or acoustical insulation systems.
1.2 The purpose of this practice is to optimize the performance and longevity of installed metal jacketing and to minimize water intrusion through the metal jacketing system. This document is limited to installation procedures for metal jacketing over pipe insulation up to a pipe size of 48 in. NPS and does not encompass system design. This practice does not cover the installation of metal jacketing on rectangular ducts or around valves and gauges. It excludes the installation of spiral jacketing on cylindrical insulated ducts but is applicable to metal jacketing on cylindrical insulated ducts installed similarly to pipe insulation jacketing. Guide C1423 provides guidance in selecting jacketing materials and their safe use.
1.3 The intrusion of water or water vapor into an insulation system will, in some cases, cause undesirable results such as corrosion under insulation, loss of insulating ability, and physical damage to the insulation system. Minimizing the movement of water through the metal jacketing system is only one of the important factors in helping maintain good long-term performance of the total insulation system. There are many other important factors including proper performance and installation of the insulation, vapor retarder, and insulation joint sealant. Optimum long-term insulation system performance is only achieved by carefully considering all aspects of insulation system design and how these relate to the intended application (hot, cold, cryogenic, severe environment, etc.). This practice only addresses installation of metal jacketing so total insulation system design is outside of its scope.
