Equipment. Provide on all equipment when temperatures are below 16 degrees C
[60 degrees F], above 40 degrees C [104 degrees F] or where condensation can occur.
Insulation shall be suitable for the temperature encountered. Insulation shall be formed or
fabricated to fit the equipment. Removable insulation sections shall be provided to cover parts
of equipment which must be opened periodically for maintenance including vessel covers,
fasteners, flanges and accessories. Supply the insulation with manufacturer's recommended
factory applied jacket.
