2.5 General Desian
.~
.1 Insulation shall have a design life of 40 years.
.2 The insulation shall form a system comprised of prefabricated units engineered as integrated assemblies to fit the surfaces to be insulated with due allowance for thermal expansion, contraction, equipment deflection, and other contingencies.
3
.3 Insulation, where required, shall be easily removed for equipment inspection and replaced with no damage to the insulation.
Removable sections shall be small enough to be handled by one man.
.4
'Each removable section shall have a permanent, easy to read, identification name and/or number on its surface.
This
~
information shall be approved by ENGINEER.
