Overview
Clock Spring Snap Wrap (SW) is an economical repair alternative for
pipelines operating at less than 500 psi (3.45 MPa). It can be used to
permanently repair external blunt defects with a depth of less than 90% of the
nominal wall thickness.
Clock Spring® Snap Wrap (SW) consists of a high
strength corrosion resistant fiberglass composite sleeve, a high performance
adhesive, and a filler material. The composite split sleeves are uniquely shaped
and sized to wrap around pipe diameters of 3/4” and larger. The individual
layers are bonded together and to the pipe surface to fully restore
serviceability.
Clock Spring® repairs are fast, economical and
easy. Since no cutting or welding is required, there are no risks to the
environment, release of greenhouse gases or waste disposal problems.
It’s simply the smartest pipeline repair decision
you can make!
