TY - CONF A1 - Bäßler, Ralph A1 - Weltschev, Margit T1 - UNS S44400 - A low cost and corrosion-resistant alternative to the austenite containing nickel for tank applications N2 - In Germany the “BAM-List - Requirements for Tanks for the Transport of Dangerous Goods” is the basis for substance-related prototype approvals for tank Containers undertaken by the BAM1 - Federal Institute for Materials Research and Testing. Compatibility evaluations of selected metallic materials as well as of polymeric gasket and lining materials under the influence of approximately 7200 dangerous goods have been published in the BAM-List since 1989. The ferritic Steel UNS S44400 (X2CrMoTil8-10, 1.4521) was originally developed as alternative for the austenitic grade AISI316L (X2CrNiMo 17-12-2, 1.4404). Due to its characteristic profile this Steel was qualified for applications requiring high strength values at concomitant adequate corrosion resistance. Because of the lack of Nickel this Steel is a cost-efficient alternative to the Ni-containing austenites. No corrosion test results of UNS S44400 under the influence of dangerous goods were published in the BAM-List so far. Only data on the behavior of AISI 316L are listed. Therefore test specimens of this Steel were exposed to selected corrosive substances in order to compare both steels. Due to the reduced alloy content a reduced corrosion resistance of the Steel UNS S44400 in acidic substances, such as formic acid, acetic acid and sulfuric acid, in comparison to the austenitic CrNiMosteels was expected but not observed. Tests in an alkaline medium showed sufficient resistance.

T1 - Compatibility of high density polyethylene grades with bioethanol-gasoline blends and biodiesel N2 - Biofuels including ethanol and biodiesel (fatty acid methyl ester) represent an important renewable fuel alternative to petroleum-derived transport fuels. Increasing biofuels use would have some benefits, such as a reduction in oil demand and greenhouse gas emissions, and an improvement in air quality. Materials compatibility is a major concern whenever the fuel composition is changed in a fuel System. The aim of this work is to study the interaction between high density polyethylene (HDPE) grades and biofuels such as E85 (fuel with 85 % ethanol) and biodiesel. 10 I jerricans made of two different polyethylene grades were filled with E85 and biodiesel and exposed to temperatures of 20°C and 40°C for one year. Tensile properties (tensile strength, breaking elongation and elasticity modulus) were determined in accordance with EN ISO 527-2 at 23±2 °C once a month, and Fourier Transform Infrared Spectroscopy (FTIR) was used to evaluate possible changes. The tensile properties of HDPE jerrican cuttings decreased, but not significantly, after immersion in E85 and biodiesel. In particular, the elasticity modulus of the polyethylene grades was reduced after exposure to biodiesel. Pin impression tests according to EN ISO 16101 were performed with test specimens of a HDPE grade in White Spirit, E85 and biodiesel. Measurements of the remaining tensile strength showed that biofuels had a stronger effect than White Spirit. The FTIR spectra of HDPE jerrican cuttings showed that immersion tests for one year with E85 at 20°C and 40°C only caused an increase in the peak of 1585 cm'1 (C=C Stretching vibrations) in the Chemical structure of HDPE. The FTIR spectra of HDPE jerrican cuttings showed that immersion tests for one year with biodiesel at 20°C and 40°C led to a broadening of the C=O peak of 1740 cm'1 and the appearance of the hydroxyl group at 3500 cm'1. Both results are explained by secondary degradation products of the polyethylene decomposition process caused by the temperature and unsaturated fatty acid content in the biodiesel since biodiesel decomposes quickly at elevated temperatures. The broadening of the C=O peak to 1740 cm'1 can be attributed to aldehyde carbonyl and ester Carbonyl groups mutually overlapping. Measurements of the melt flow rate (MFR) showed an increase in the MFR with immersion time in biodiesel due to the unsaturated fatty acid formed in the biodiesel. Diffusions of oxygen and rapeseed methyl ester increase the Chemical impact on polyethylene grades.

Zu den Hauptschadensursachen zählt die Korrosion, wobei die gleichmäßige und ungleichmäßige Flächenkorrosion die Korrosionsart ist, die beim Chemikalientransport in Tanks am häufigsten auftritt. Viele Schäden durch Lochkorrosion entstehen beim Transport von chloridhaltigen Medien bei Anwesenheit von Feuchtigkeit. Mechanische Schäden sind meist auf eine langfristige Überlastung zurückzuführen und treten erst nach längerer Betriebszeit auf. Betriebsbedingte Fehler entstehen durch Unachtsamkeit des Personals beim Be- und Entladen der Tanks an den Armaturen. Durch Verkehrsunfälle wird der Tankkörper oder der Rahmen beschädigt.
