Cathodic protection (CP) is an electrochemical corrosion prevention technique, which is implemented by circulating a direct current between an electrode (anode) placed in the environment and the structure to be protected (the cathode): this current causes a lowering of the potential of the metal and reduces its corrosion rate, until it stops.

Sour Service Qualification of Carbon Steels (SMYS 450 MPa) and Their Welds Considering Field H2S Fugacity / Dissolved H2S Concentration - Qualification at Design and Atmospheric Pressure

A Sulfide Stress Cracking (SSC) qualification program was conducted for carbon steel components (piping, flanges, and fittings with SMYS 450 MPa) and its welds for an offshore facility piping system that may carry off-spec gas in the event of a temporary malfunction of the dehydration and H2S removal units. The off-spec sour gas may contain 22% mol CO2 (pCO2 73 bara) and 6,700 ppm H2S (pH2S 2.22 bara) at a total pressure of 332 bara and temperature of 24 °C with condensed water pH of 3.2. The SSC qualification program included two parts. Part I involved testing at 332 bara using batch-loaded high-pressure autoclaves based on H2S fugacity (fH2S) as permitted by NACE MR175/ISO 15156-2. Part II involved testing at atmospheric pressure by matching the predicted dissolved H2S concentration of the aqueous phase (cH2S) and by matching the predicted fH2S of the gas. Part I and Part II tests were conducted using the same set-up (NACE TM0177 Method A tensile) and stress (75% AYS). Hardness readings taken at the base material (BM), heat affected zone (HAZ) and weld metal (WM) were below 250 HV10 near the root and mid-section of the rings (with couple of single reading exceptions along the HAZ for the rings involving flanges and fittings). Hence, most of the tested carbon steel rings could have been considered suitable for sour service through compliance with NACE MR0175 /ISO 15156-2. Nevertheless, post-examination of test specimens revealed susceptibility to SSC in both Part I and Part II tests. These lab results suggest that NACE MR0175 /ISO 15156-2 guidance on carbon steel SSC resistance, which is based on hardness, is not always conservative.

This is a print-on-demand (POD) book that will be produced just for you, and should arrive to your door about from six to eight days after your order; allow two to three weeks for international orders.

To stay competitive in the corrosion industry, companies must continually be looking for more efficient, safe, and cost-effective ways to inspect and maintain assets. There are many opportunities for the increased use of robotic solutions in all aspects of the corrosion industry, but the primary reasons focus on limiting human intervention for both safety and accuracy.

This book presents the reader with multiple examples of the use of robotic unmanned and remote-controlled systems, be they underground, on the ground, or in the air.

It is a well-admitted fact that oxygen contamination shall be avoided during standard H2S cracking tests. Until 2016 NACE technical methods related to H2S cracking resistance evaluation (e.g. NACE TM0284 and NACE TM0177) only gave general suggestions about O2 pollution. For instance it was recommended that ‘tests vessels shall be capable of being purged to remove O2’ and also that ‘O2 contamination is evident by a cloudy appearance’. In the 2016 revisions of NACE TM0177 and NACE TM0284 documents quantitative limits of O2 contamination were included:- Test method must ensure that the test solution contains less than 50 mass. ppb dissolved O2 before the introduction of H2S.- A more stringent limit of 10 ppb max. is imposed when testing Corrosion Resistant Alloys (CRA) or high strength low alloy steels (> 80 ksi).However the scientific basis of these values have not been well-established yet and there is still a lack of available experimental data to illustrate the potential impacts of small dissolved oxygen contents on the cracking resistance of different materials. In addition while the revised test methods explicitly address initial contamination of the test solution before H2S introduction they do not consider a continuous oxygen supply during testing. This possible continuous O2 contamination is extremely difficult to eliminate and control for example in case of poor laboratory practices oxygen ingress may arise by permeation through polymer tubings used for the tests or in case of a lack of tightness of gaskets.In order to better understand the impact of O2 contamination on H2S cracking a 3-years Joint Industrial Project (JIP) was launched at the end of 2015. The objectives were to evaluate if continuous O2 contamination can affect H2S cracking test results. A range of steel grades covering different types of O&G applications such as line pipe OCTG and flexible wires were used. Sulfide Stress Cracking (SSC uniaxial tensile as well as 4 point-bend tests) and Hydrogen Induced Cracking (HIC) tests were conducted with well-controlled and continuous O2 contamination. Three levels of O2 partial pressures in the gas feed corresponding to 300 ppb 50 ppb and less than 10 ppb dissolved O2 were used. These levels were selected to simulate poor deaeration and the current limits specified in the last standard revisions respectively.In parallel to the standard qualification tests hydrogen permeation and weight-loss corrosion experiments were performed with the same test matrix covering all regions of the SSC severity diagram. This paper aims at sharing the main results of this JIP.
