GB/T 43117-2023 for fiberglass reinforced thermoset plastic (GRP) pipe, specifies the wet state or dry state under the ring creeping performance measurement method. The standard specifies the test equipment, such as loading device, environment control box and other technical parameters. Detailed description of GRP tube sample preparation, including sample interception, size measurement. Standardize the test process, covering loading method, loading time, environment temperature Humidity control and data recording and analysis. This can accurately determine the GRP pipe ring creeping performance, providing key mechanical properties for its design and application in water supply and drainage, chemical industry and other fields, to ensure the long-term use of pipelines safety.
