# 2021 Amsterdam

Unplasticized polyamide 12 (PA-U12) is increasingly being used in pipe applications, especially in the gas sector. However, the material behavior in the usual quality tests for pipe welds has not yet been thoroughly investigated. For this reason, two research institutes, worked in cooperation with a manufacturer of PA-U12 to examine the established quality tests for pipe welds in PA-U12 pipes. Among the test methods were destructive test methods as well as ultrasonic inspection methods for non-destructive testing of pipe welds. The results provide an insight into the assessment of the quality characteristics of PA-U12 pipe welds and will be used for the training of personnel as well as for the extension of international technical standards.
