The ability of repair specialist, Hydratight, to repair a chemical tank at speed with the

Loctite Composite Repair System, saved its customer from serious consequences.

on a chemical tank during a routing
inspection of the operator’s
Wprocessing facility, it needed to be
resolved quickly, not only to restore compliance with
stringent environmental legislation but also to
prevent production losses.
As the large holes and pitting marks that
Hydratight discovered were in the roof of the
chemical tank, some 14 metres off the ground, the
first task was to construct scaffolding to provide
access. As a welded repair was unsuitable for this
area, Hydratight proposed the Loctite Composite
Repair System. This is a proven solution with a
great track record that Hydratight uses to restore
vessel integrity and safeguard health and safety,
especially when time is of the essence.
Central to Henkel’s Loctite Repair System is a
resin-based composite material reinforced with
fibres. When used for steel pipelines and structures,
the material reinforces and seals the damaged from 1 – 3. When used to repair steel pipes, it can
