铝塑复合管在国内外供暖行业发展迅速,室内采暖分户热计量系统型式的发展需要性能优异的铝塑复合管。虽然铝塑复合管的基本结构大致相同,但材质和加工工艺的不同使得铝塑复合管种类较多,各类型管材性能及适用环境有较大差异,正确选择和使用铝塑管应考虑其性能、使用条件、连接方式及防腐等。耐高温聚乙烯(PERT)对接焊铝塑复合管及其双热熔连接方式目前是太阳能系统和集中式分户计量供暖下供下回式系统的优选管材类型及连接方式。
Aluminum-plastic composite pipes have developed rapidly in the heating industry at home and abroad, and the development of indoor heating individual heat metering systems requires aluminum-plastic composite pipes with excellent performance. Although the basic structure of aluminum-plastic composite pipes is roughly the same, the different materials and processing technologies make the types of aluminum-plastic composite pipes more diverse. The performance and applicable environment of various types of pipe materials are quite different. Correct selection and use of aluminum-plastic pipes should consider its performance. , conditions of use, connection methods and anti-corrosion. High-temperature polyethylene (PELT) butt-welded aluminum-plastic composite pipe and its double hot-melt connection are currently the optimal pipe types and connection methods for solar energy systems and centralized metered heating under the next-feedback system.
