Application instruction – Circumferential pipe wrapping on

®
top of Stopaq Wrappingband
General Outerwrap HTPE should be applied with tension
by pulling the roll of material gently.
Wrapping direction Horizontal pipelines should be wrapped
circumferentially from left-to-right or from right-
to-left. Pipelines positioned with an angle
deviating from horizontal should be wrapped
from bottom to top (e.g. with risers).
Spiral wrapping Start wrapping Outerwrap HTPE with one full
circumferential wrap perpendicular to the pipe,
leaving 3 mm of the previously applied Stopaq®
Wrappingband visible at the boundary.

After the first circumferential wrap, consecutive

wraps should have an overlap of ≥ 50%, which
can be created by slanted and spiral application ®
