6 - STANDARD SIZES OF INTERSOL ® PEX-b
Standard pipe dimensions depend on the field of application and typical standards of each nation.
Above all, distinction can be made between two sectors, namely:
-Floor heating and connection of radiators
-Plumbing systems
6.1 - Floor heating and connection of radiators
Two types of pipe can be used, namely:
a) with oxygen diffusion barrier, consisting of a film of coextruded ethylene vinyl alcohol (EVOH)
