Storage Temperature for FRP lined vessel / PP Internals 2

[Soft2008]

We are purchasing a ASME Sec. VIII Div. 1 Washing drum for AXEN's CCR unit. Material is CS + 4 mm thick FRP lining for the corrosion protection and to avoid the direct fluid contact with the metal surface. Drum Internals are FRP /Poly Propylene material.
Design : 5.6 barg @ 80 deg C
Operating : 3.7 barg @ 45 deg C

But Client datasheet also have a note
"All pieces of internals shall be carefully handled and stored at temperature not exceeding 30°C."

Since site ambient condition is around 40 deg C, it is practically difficult to maintain the storage temp 30 degC during transportation. Does any other engineer have similar experience to sense the reason for the max. 30 deg C only requirement by AXENS? Please share your thoughts.

IMO, this's a good question to clarify with Client why the required temperature to store and handle the material as specified.
On the other hand, is it "difficult" or "impossible" to keep the material under 30 Deg-C during the transportation?
What's the "actual" handling cost to transport the material under the specified temperature?

I would think they don't want the steel to be heated from the outside (sunshine) therefore expanding at a faster rate than the lining and destroying the bond between them...
Just a guess though...
Shade the drums using white tarpaulins leaving some air gap over the vessel during transport might be some sort of a solution.
