Investigation of damage to organic materials in chemical apparatus engineering . There are many different possible causes for the failure of structural elements or of linings and coatings made of organic materials under such load conditions as those found in chemical plant. Despite the general suitability of the engineering plastics used, design and manufacturing defects are often the cause of premature failure. Installation faults are also found on occasion. Other sources of damage include the chemical and physical effects of media on organic materials. These are due in part to the unsuitability of the material used, the effect of corrosive components in the media involved often being either not recognized or underestimated; on the other hand, the damage may also be caused by inherent stresses in the structural elements in conjunction with the physical or chemical effects of the media, resulting in stress cracking or stress corrosion cracking. Damage cases of this type are described on the basis of numerous examples, the causes ascertained through intensive investigation of the damage and suitable remedies described.
