Description
L = length of main pipe
Reduction pieces are pre-insulated in the factory
in the same way as the plastic casing pipe, and
they conform to EN448. They are manufactured
with a concentric reduction piece to EN 10253 and
a welded-on pipe cylinder. For static reasons, pre-
insulated reduction pieces are designed to reduce
the dimension by a maximum of two steps.
