CORROSION UNDER INSULATION (CUI)

STOPAQ® system: Corrosion Under Insulation (CUI)

STOPAQ® protection systems offer high performance protection against CUI, a commonly occurring corrosion mechanism that mainly affects processing infrastructure, including pipelines in oil and gas industries, chemical processing and other offshore installations. This type of corrosion is recurrent in pipelines with thermal, acoustic and fireproofing insulation.

STOPAQ® system provides the impervious barrier to protect any metal substrates from condensing moisture and subsequent corrosion. Application of STOPAQ® systems do not require operation shutdowns, with products suitable for direct application on condensing and wet substrates.

STOPAQ® SYSTEM: CZH PASTE

CZH Paste

STOPAQ® Paste CZH is a mouldable corrosion preventing compound that is used for filling of voids and levelling of irregular surfaces prior to application of STOPAQ® coating materials. It adheres extremely well to steel and factory applied pipeline coatings like PE, PP and FBE. It is a non-toxic, cold-applied compound, based on non-crystalline, low-viscosity, non-crosslinked (fully amorphous), pure homopolymer Polyisobutene.

The compound does not cure and is unable to build up internal stress. STOPAQ® Paste CZH is fully resistant to water, salt spray and UV-radiation, and has a low gas- and water vapour permeability.

STOPAQ® Paste CZH requires application of additional flexible mechanical protective layers like STOPAQ® Outerwrap. This supports self-healing ability of small damages like dents and cuts in the complete STOPAQ® coating system, and improves impact and indentation resistance.

APPLICATION

Flanges: For protection against external corrosion and shaping of connection flanges, insulation flanges and blind flanges.

Valves: For protection against external corrosion and shaping of valves.

Irregular shaped parts: For protection against external corrosion and shaping of manhole covers, bolts & nuts, etc.

Cad-welds: For protection against external corrosion of welded CP-wire connections on underground pipelines (Pin-brazes) and underground steel structures protected by CP.

Pipe coating repairs: For protection against external corrosion and as filler for pipeline coating defects of e.g. 3LPE coated pipelines, prior to application of consecutive coating materials.
