Detection method of PE electrofusion pipe fittings:
The detection method of HDPE electrofusion pipe fittings includes the percentage of breaking elongation: the percentage of breaking elongation is one of the manifestations of good flexibility of the pipe.
Through the lateral determination of the pipe breaking elongation (percentage of breaking elongation), it is confirmed that the pipe retains the performance of the raw material, the convenience and economy of construction are ensured, the adaptability of the pipe to the uneven settlement of the foundation is ensured, and the needs of seismic performance are met.
After the pipe is exposed to the combined effects of natural climatic conditions such as sunlight, heat and cold, wind and rain, and oxygen, its strength, thermal stability and percentage of breaking elongation will be reduced.
Through the determination of the weather resistance of bamboo, it is confirmed that the pipe retains the performance of the raw material, and it is guaranteed that the pipe can still meet the requirements of use after receiving a certain performance praise.
Resistance to slow crack growth:
Through the measurement of the slow crack growth resistance of the HDPE pipe, it is confirmed that the pipe retains the slow crack growth resistance of the raw material to ensure the authentic load capacity and long-term service life of the pipe.
Heat quality qualitative:
Through the side determination of the thermal stability of the pipe, it is confirmed that the pipe retains the original performance of the raw material, and it is guaranteed that the part material can still meet the use requirements during construction, welding and 50a service period.
Melt Mass-Flow Rate:
By measuring the melt mass flow rate of the pipe and comparing it with the MFR of the raw material, it is required that the difference does not exceed 20%, and it is confirmed that the pipe basically retains the original performance of the raw material, so as to ensure the reprocessing process of the pipe and welding performance.
