Corrosive environmental media may lead to a significant degradation of the mechanical properties of the materials. Individual experimental investigation and analysis concepts are available at the Institute of General and Analytical Chemistry for the evaluation of different materials under pressurized hydrogen. Hydrogen technologies will enable decarbonization.

As part of the Horizon 2020 project HyStories, the possibility of hydrogen storage in old, depleted gas reservoirs and natural gas storage facilities is being investigated throughout Europe. Within the scope of this project, the work package “materials and corrosion” has the objective of testing the applicability of selected pipe materials with respect to hydrogen embrittlement. For this purpose, a welded carbon steel grade J55 with a ferritic-pearlitic microstructure was investigated by using high pressure high temperature autoclave tests, permeation tests and analysis of uptaken hydrogen. For the autoclave tests, tensile samples have been examined that were loaded by a spring at 90% of yield strength, and samples were also examined to determine the hydrogen uptake. After completion of the tests, the hydrogen uptake was analyzed by thermal desorption spectroscopy. Four main gas compositions were used for the autoclave tests: 120 bar H2, 120 bar H2 + 15 bar CO2, 120 bar H2 + 1 bar H2S, and 120 bar H2 + 15 bar CO2 + 1 bar H2S whereby the tests were carried out with and without the addition of electrolytes with a concentration of 1 and 200 g/l sodium chloride. Moreover, the experiments were conducted at room temperature and 120°C. Test duration was 720 hours. Prior to autoclave testing effective diffusion coefficient was determined to characterize diffusion behavior of hydrogen through the weld material. Results show a low hydrogen uptake even at most severe conditions. Additionally no specimens failed during autoclave constant load testing. Welded J55 is recommended as a suitable tube material for subsurface hydrogen storage.

At the time of a recent maintenance shutdown, cracking was discovered in the repads and parent material in the vicinity of several nozzles along the bottom of two in-situ production treater vessels. Some of the cracks were reported to be through-wall. The vessels were commissioned in 2009 and had been in service for about 13 years before the cracks manifested as through-wall.

Atomic hydrogen can enter metallic microstructures from deposition processes like Cr plating or phosphatizing, chemical and electrochemical pickling treatments, during welding operations if the humidity of consumables is too high, by cathodic processes resulting from corrosion phenomena or contact with high pressure gaseous hydrogen. According to different chemical-physical mechanisms, atomic hydrogen can enter the metallic structure resulting in damages of various forms, such as HIC (hydrogen induced cracking), SOHIC (stress oriented HIC), delayed fracture and hydrogen embrittlement (HE).

Once polymers are used reliably in a specific service, they become the material of choice due to their cost effectiveness. However, to choose and apply polymers dependably, one must consider their unique properties – they are different from the metals we use industrially. Through various examples of damaged and failed parts, this paper illustrates fundamental information about choosing, using, and keeping polymers in service. Polymers are subject to permeation, oxidation, aging, fatigue, installation damage, and other damage.
