1. Long-term compressive performance, only in terms of design plan, the compressive performance of standard stamping elbows. However, because of the elements at all levels, the specific wall thickness of the floor heating pipe is generally 2mm. Under this thickness, all kinds of pipes can be considered for floor heating regulations, and the compressive advantages of standard stamped elbow pipes cannot be reflected;

2. Heat transfer: The pipes used for floor heating have good heat transfer.
3. Ultra-low temperature and high temperature resistance: PE-RT and PEX have better cold and impact resistance. During winter construction measures, the pipes are not easily damaged and cracked, which improves the coordination ability of project construction allocation.
4. Thermal insulation: PE-RT can be used comprehensively without environmental pollution. And PEX cannot be purchased, which will cause secondary pollution;
5. Reliability of production and processing performance: PEX has problems such as manipulation of chemical cross-linking degree and chemical cross-linking precision. The production and processing are complicated and the production and processing immediately harm the performance of the pipe.
