Corrosion Under Insulation (CUI)
Protect against corrosion and reduce waste, HSE risk while prolonging lifetime of equipment
Water and air will find its way through various layers of coating due to movements, hardening of sealants and damages to shielding.
The re-establishment of a paint system under insulation is a high-cost operation; removal of insulation, surface preparation, sandblasting and paint x 4 layers. Extending the interval length of when this process is needed, is key. As is the reduction in time spent for the surface preparation operation.
The STOPAQ system can be put under insulation, on pipes, welds, and on structure. It eliminates water and oxygen intrusion and hence avoids contact with the steel surface, wherever the water and air come from.
By applying STOPAQ wrapping on your new-build asset or as a maintenance system, STOPAQ will most likely surpass as protection system beyond the lifetime of the asset. The design lifetime is over 30 years.
|Correction Protection System||Surface Treatment Requirements||Lifetime 20 year +||Safety and Environmental Impact||Chemical Exposure / VOC|
|Epoxy/Liquid Coating||SA 2 (ISO8501)|
|Metallization||SA 2 (ISO8501)|
|STOPAQ Wrappingband||ST 2 (ISO8501)||30 year +||99 % less waste / 91% less CO2|
Surface prep ST2 (mechanical hand tool, wire brush acc. ISO 8501) vs. SA2 (garnet blasting) makes a huge impact in time savings, waste and safety. No dust, VOC or noise.
Application of the STOPAQ System is manual, hence no garnet blasting, primer or pre-heating is required. STOPAQ can be applied on all metal alloys, cured liquid coating, TSA, PP, PE, nylons and various rubber types.
STOPAQ can easily be applied at in-service pipelines, up to 1200C, with no risk of under creep, osmosis, cracking or bridging. No need to shut down operations; a huge cost saving potential.
The STOPAQ series portfolio includes solutions for above ground, below ground, under water applied, condensing lines and complex structure geometry. With STOPAQ as the preferred corrosion protection system, your operator will work without additional HSE risk and the reduction of waste compared to blast and paint is nearly 99%.The CO2 emission reduction is estimated to 91%, compared to blast and paint solutions.
