Testing Method of PE Electro Fusion Pipe Fittings

Elongation at break: elongation at break is one of the performance of good flexibility of pipe. Through the lateral determination of the elongation at break of the pipe, it is confirmed that the pipe retains the properties of raw materials, ensures the convenience and economy of construction, ensures the adaptability of the pipe to the uneven settlement of the foundation, and meets the needs of seismic performance.

The Climate Resistance: the strength, thermal stability and elongation at break will be reduced after the pipe is exposed to the comprehensive factors under natural climatic conditions such as sunlight, hot and cold, wind and rain, and oxygen.

Resistance to Slow Crack Growth: by measuring the resistance to slow crack growth of the pipe, it is confirmed that the pipe retains the resistance to slow crack growth of the raw material, so as to ensure the load capacity and long-term service life of the pipe.

Thermal Quality:  Through the determination of the thermal stability of the pipe, it is confirmed that the pipe retains the original performance of the raw material, and that the 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, the difference should not exceed 20% to confirm that the pipe basically retains the original performance of the raw material, so as to ensure the reprocessing process and welding performance of the pipe.
