05021 A Critical Review of Current Performance Tests for Offshore Anti-Corrosive Coatings

Product Number: 51300-05021-SG

ISBN: 05021 2005 CP

Author: David Claydon, International Paints UK; Michael J. Mitchell and Darren Ward, International Protectiv

Publication Date: 2005

This paper will critically review the current philosophies described in ISO and NACE anti-corrosive performance test standards, taking into consideration correlation with natural exposure, track record, validity of "acceptance" or "pre-qualification criteria", dry film thickness and suggested areas for improvement.

The environmentally-assisted cracking (EAC) of three wrought corrosion-resistant alloys (CRAs) with a minimum yield strength of 110ksi (760MPa) was investigated between 70°F (21°C) and 450°F (232°C) through weekly thermal cycles totalizing 42 days. The thermal cycling was introduced to approximate service equipment conditions and gain additional confidence on the EAC-free limits of all three CRAs. Alloys 17-4PH, K-500, and 925 were selected and exposed to a 180,000-ppm NaCl brine (pH=2.75) in equilibrium with 1000 psi (68.95 bar) H2S, 1000 psi (68.95 bar) CO2, and 2500 psi (172.37 bar) CH4. All three CRAs were (a) acquired as per the NACE MR0175/ISO 1516 requirements (1), (b) tested as per NACE TM0177 Method C at 30-to-90% of the CRA minimum specified minimum yield strength (SMYS), and (c) also compared for their weight-loss corrosion and localized corrosion. The results show: (a) Alloy 17-4PH remains resistant to EAC below 45% of its SMYS, (b) Alloy K-500 resists cracking at an estimated 80% of its SMYS, but uniformly corrodes by sulfide conversion under film at a rate of 64 mpy (1.63 mm/yr.), and (c) Alloy 925 continues to be immune to EAC at 90% of its SMYS. Alloy 17-4PH also corroded at a rate of 22.8 mpy (0.58 mm/yr.) in comparison to only 0.6 mpy (15.2 mm/yr.) for Alloy 925, with no CRA showing experiencing crevice corrosion.

Corrosion under thermal insulations namely CUI (Corrosion under insulation) is a key degradation process in hydrocarbon facilities which poses asset integrity risks. 1 CUI is reported as the reason behind 40-60% of failures of the process piping in a typical oil refining facility. Speaking smaller-sized process piping (i.e., NPS < 4”), up to 81% of reported failures are known to result from CUI. 2 Monetary spending to inspect and fix CUI-related failures cost 10% of overall maintenance budget in a typical medium-sized oil refinery. 2 CUI risk is influenced by numerous operational and environmental factors which impedes its management in a typical AIM (Asset integrity management) program.

The drive towards renewable energy, requirement for reduction in fossil fuel consumption and emission of carbon dioxide has received substantial attention from governments and researchers worldwide during the last few decades [1]. The exploration of renewable sources of energy has been grouped into wind, geothermal, tidal and solar energy. Solar energy has shown great promise due to the abundant amount of energy reaching the Earth [2, 3]. Electricity generation from solar irradiation can be achieved by photovoltaic (PV) and photothermal conversion [4].

Thermal & Moisture Cycling Impacts on the Corrosion Behavior of Carbon Steel Under Contacting and Contact-Free Insulation

Corrosion under thermal insulations namely CUI (Corrosion under insulation) is among the key degradations posing integrity risks to the hydrocarbon processing, chemical, and petrochemical facilities. CUI is reportedly known as the reason behind 40-60% of failures in the piping for the oil refineries. Whereas the small-bore piping (i.e., NPS< 4”) is more prone to this damage mechanism where reportedly where up to 81% of failure result from CUI.
