settlement and lateral movement.
In order to establish and maintain the
necessary pipe alignment, adjustable roller and
fixed supports provided vertical and horizontal

established level of each support. Expansion and
contraction of the pipes and the manifold in
the mirror house, due to temperature and pressure changes, were compensated for by using
all metal expansion joints.
