How to choose specific Abyssalite to insulate walls or pipes?

Question

To insulate pipes, I would like to use a specific Abyssalite with the correct temperature. It seems, that the temperature will be "remembered" from the place of origin. You can see that in the temperature overlay.

How can I choose a "cold" Abyssalite to cool down a pipe and prevent the use of "hot" Abyssalite for this purpose?

Answer 1

You can't choose the temperature of the materials you are using to build.

What you can do is:

• Mine the desired Abyssalite and store it in a designated Compactor (use sweep only, choose only Abyssalite to be stored and isolate the place with a mechanized airlock and proper access control)
• Move the Abyssalite to the place you want to use it with the same techniques as above
• Build your pipes, again with proper control : lock up the area to ensure that no Abyssalite goes in except the one you choose.

but if you only want insulate pipes, why not using some insulated pipes ?

Answer 2

It doesn't matter. Abyssalite is so poor at conducting heat that you can build scorching hot pipes out of it in a cold biome and it will never do anything.

Insulated pipes (like insulated tiles) use twice the material and allow for 20% of the heat transfer through it. With Abyssalite this is completely brokenly overpowered for heat transfer.
