1.1.This guide covers recommended installation techniques for aluminum and stainless steel jacketing for thermal and acoustical pipe insulation operating at either above or below ambient temperatures and in both indoor and outdoor locations. This guide is applicable to materials manufactured in accordance with C1729 (aluminum jacketing) or C1767 (stainless steel jacketing) or other types of metal jacketing. It does not cover 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 guide is to optimize the performance and longevity of installed metal jacketing. This document is limited to installation procedures for metal jacketing over pipe insulation and does not encompass system design. This guide does not cover installation of metal jacketing on rectangular ducts. It excludes guidelines for spiral jacketing of cylindrical ducts but is applicable for metal jacketing on cylindrical duct installed similarly to pipe jacketing. Guide C1423 provides guidance in selecting jacketing materials and their safe use. 1.3.The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4.This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Leakage of water from rain and melting snow into pipe and equipment insulation, on systems located outdoors, is commonplace. This compromises the thermal performance of the insulation system, can lead to corrosion under insulation (CUI), and can lead to deterioration of the insulation materials. Use of correct installation techniques can result in the exclusion of water from the insulation, prevention of CUI, and a longer life for both the insulation system and the pipe or equipment being insulated.
