AS 4426-1997 Thermal insulation of pipework, ductwork and equipment - Selection, installation and finish
Standards Australia
Reconfirmed by: AS 4426-1997 REC:2018 Thermal insulation of pipework, ductwork and equipment - Selection, installation and finish
The objective of this Standard is to provide good practice procedures relating to the installation of insulation to mechanical services for use by designers , specifiers, regulators and inspectors of these systems. The Standard outlines requirements and guidelines for the process of selecting and installing thermal insulating systems for mechanical plant and services operating in the range of −75°C to +800°C.
The term ‘informative’ has been used in this Standard to define the application of the appendix to which it applies. An ‘informative’ appendix is only for information and guidance.
During the development of this Standard cognizance was taken of the technical requirements and contents of BS 5970, Code of practice for thermal insulation of pipework and equipment (in the temperature range −100°C to +870°C).
This Standard deals with the selection, installation and finish of thermal insulation for pipework, ductwork, tanks, vessels and equipment in the temperature range −75°C to +800°C but excludes manufactured pre-insulated equipment,structural insulation of buildings and cold stores, fire proofing structures, refractory linings of plant, airborne installations and all external underground mains.
NOTES :
1 The Standard may be found to be generally applicable to the insulation of road and rail transport vehicles and of some assistance in marine insulation.
2 Appendices to the Standard provide guidance on inspection, testing and maintenance (Appendix A), protection against condensation (Appendix B), protection against corrosion (Appendix C) and relevant Australian Standards on insulation materials (Appendix D)
