Zu den Hauptschadensursachen an Rohrleitungen zählen Korrosion, Druckstöße und Kavitationsschläge, Zeitstandbeanspruchung, struktur- und fluidmechanische Schwingungen, Fremdberührungen, elektrische Fremdbeeinflussung und geologische Besonderheiten im Bereich des Rohrleitungsverlaufes.

The aim of this work was to study the interaction between high density polyethylene (HDPE) with permeation barriers in form of polyamide (PA) and fluorination, and biofuels such as E85 (fuel with 85 % ethanol), biodiesel and B10 (heating oil with 10 % biodiesel). 10 l jerrycans made of polyethylene with permeation barrier of PA were filled with E85 and biodiesel and exposed to temperatures of 20 °C and 40 °C for 5 years. Half of the 20 l jerrycans of HDPE for filling with B10 were fluorinated at the inner layer to prevent permeation before the exposure. Tensile properties were determined once a year, and FTIR-spectroscopy was used to evaluate possible changes. The tensile properties tensile strength and breaking elongation of HDPE jerrycan cuttings with permeation barrier decreased, but not significantly, after immersion in E85, biodiesel and B10. The elasticity modulus of the polyethylene grades was especially reduced during exposure to E85. The FTIR spectra of HDPE jerrycan cuttings with permeation barrier showed that immersion tests for five years with the test fuels at 20 °C and 40 °C did not lead to a decomposition of the permeation barriers.

For the material properties of tanks in the “BAM-List – Requirements for Tanks for the Transport of Dangerous Goods” specifications for the sub-stance prototype approval for tank materials are listed. Further compati-bility evaluations of selected metallic material groups as well as of poly-meric gasket and lining materials under the influence of dangerous goods are published in the List. There are a large number of highly corrosive dangerous goods listed, in which conventional steels are not resistant. Chemical companies, transportation providers and tank producers need tanks made of corrosion-resistant materials (corrosion retardant materi-als) in order to protect the tank shell. The application of high-alloyed stainless steels and nickel alloys as there are alloy 926 (1.4529; X1NiCrMoCuN25-20-7), alloy 31 (1.4562;X1NiCrMoCu31-27-7) and Nickel-Chromium-Molybdenum Alloy 59 (2.4605; NiCr23Mo16Al) is an al-ternative solution compared with the lining of the tanks with a polymeric material. Due to the limited number of corrosion test results with welded test sam-ples of these high-alloyed materials under the influence of corrosive dan-gerous goods BAM, Institute for Corrosion Protection (IKS) Dresden and ThyssenKrupp VDM have been performing a comprehensive test program since 2002. The program comprised corrosion resistance evaluations of the three high-alloyed materials exposed to substances representing cor-rosive dangerous goods such as inorganic halogenides, organic acidic halogenides, sulfonic acids and nitrating acids.
