[0002] With the booming development of the floor radiant heating industry in my country, floor heating products are flourishing, and pipes, the core material of the entire floor heating system, are particularly attracting attention. PE-RT pipes can be used in temperatures exceeding 80°C, allowing polyethylene pipes to be used in high-temperature applications without the need for cross-linking and capable of fusion connection. As a new type of medium-density polyethylene, PE-RT (heat-resistant polyethylene) is gaining increasing attention for its application in floor heating. However, during actual installation on site, pipes are easily affected by external forces or substandard raw materials, resulting in bending and damage.

[0003] At present, the bending test of PE-RT floor heating pipes has the following shortcomings: 1. The raw materials of PE-RT floor heating pipes are uneven or violently constructed, resulting in bending of the pipes during the construction bending process; 2. The bending performance of the pipes is usually determined by manually bending the pipes to confirm whether the pipes are qualified. However, since the manual bending force, bending angle and bending radius cannot be quantified, the bending performance test of the pipes does not meet the standards. Utility Model Content
