1. Coverings Systems Range Arma-Chek

2. Covering Systems 2 Main target: provide UV protection and increase the insulation life expectancy reduce risk of CUI protect insulation against mechanical impact protect from salt water, extreme weather conditions

3. Arma Chek provide exceptionally high resistance against UV, oil, chemical and extreme weather. 3

4. Arma Chek helps to reduce the risk of CUI 4  Offshore applications  Marine and ship building  Petrochemical industries  Energy plants & storage facilities

5. CUI = Corrosion under Insulation / The Challenge  CUI is often difficult to identify because it is hidden beneath insulation and jacketing until it becomes a more serious problem…  how does CUI occur? - insulation covering is breached - water ingress into the insulation - water and oxygen reach the metal surface 5

6. Corrosion – mechanism 6 wet corrosion presence of moisture (water, humidity) containing oxygen galvanic corrosion contact (also through wet insulation) of two metals with different electrode potentials; metal cladding can be affected by this type of corrosion Stress Corrosion Cracking (SCC) occurs in austenitic stainless steel if exposed simultaneously to the three trigger factors: - stresses within the metal - moisture - halogen ions (chloride, bromide, etc.) rust product: Fe(OH) 2 and Fe(OH) 3 Corrosion Under Insulation (CUI) is accelerated by: - availability of oxygen - high temperature - concentration of dissolved ions.

7. Additional consequences of CUI Insulation often requires replacement within several years at a cost of up to € 600 per linear meter. As well as CUI, water ingress can lead to weight gain and a significant reduction in both thermal and acoustic performance: 7

8. CUI – what cost? 8 The highest incidence of leaks in the refining and chemical industries are due to CUI and not process corrosion. Between 40% and 60% of piping maintenance costs are CUI related. The problems caused by CUI caused the oil & gas industry to consider moving away from mineral wool insulation.

9. CUI / Corrosion Under Insulation 9 Material with open cell structure Elastomeric material with closed cell structure External vapor barrier = concentrated diffusion resistance Ambient air Partial pressure of water vapor Closed cells = distributed diffusion resistance Fibrous and Open Cell Risk Risk of Fluid/Pressure Loss Wicking Galvanic Corrosion Water Spray / Moisture 100% protection from external vapour barrier and metal cladding Resistance to Water Vapour Diffusion No 1 risk to industry is CUI

10. CUI / Corrosion Under Insulation 10 Elastomeric, Closed-Cell Foam (FEF)  minimise the risk of CUI Material with open cell structure Elastomeric material with closed cell structure Partial pressure of water vapor Closed cells = distributed diffusion resistance Water Spray / Moisture 100% protection from Nitrile Rubber External vapor barrier = concentrated diffusion resistance Resistance to Water Vapour Diffusion Ambient air
