目前，国际上普遍认为最适宜作为辐射采暖的管材，是PE-RT和PE-X管，尤其是PE-RT管，不仅承压和耐温适中，便于安装，能热熔连接，而且废料能回收利用，不会形成“白色污染”，符合环保要求。
希望我的回答能够帮助到您。

我是牵绊 07-02 05:42

用于地暖系统的管材主要有PE-X管、PE-RT管、PPR管、PE管四大类，由于原材料以及生产工艺不同，这四类地暖管材的的质量、特性也不尽相同。
1.PE-X管：低温韧性好，耐高温，抗应力开裂性好，没有热塑性能，不能用热熔焊接的方法连接和修复，只能采用金属管件机械连接，长期使用易发生漏水。
2.PE-RT管：保留了PEX管的优点，管材可以通过热熔连接，接头可靠，不易发生渗漏，柔韧性和耐低温性能很好，并且材料价格适中，性价比较高，是目前地暖采用中的通用管材。
3.PB管：具有耐压性能高，耐高温和低温性能好的特性，抗冲击性能好，容易弯曲而不反弹，是几种地暖管材中最柔软的。原料价格最高，是其它品种的一倍以上，当前在国内应用较少。
4.PP-R管：耐高温性能好、力学性能好和连接性能优越，无毒、卫生，是生活热水与散热器系统用管的理想管材，但由于其耐低温冲击性能差，使得在地暖用管方面应用较少。
希望我的回答对您有所帮助。

目前在新型供暖方式上应用较为广泛的是低温热水地板辐射供暖系统(以下简称地暖系统)。地暖系统是以不高于70℃的热水做热媒，将加热管埋设在地板中的低温辐射供暖，其使用舒适、头爽脚暖，而且热效率高，节约能源。
地暖系统属于隐蔽工程，管材的选择尤为重要。地暖水管应具有耐老化、连接方便可靠、卫生环保等特性，使您在冬日能够安心地享受地暖技术带来的春天般的温暖。随着塑料管材的成功应用，使地暖系统普及开来。塑料管材有十几种，能用于地暖系统的并不多。主要交联聚乙烯PE-X管、耐高温聚乙烯PE-RT管等几种。
PE-X管应用于地暖系统时，仍具有一些弊端。一是卫生性能差，长期使用会产生异味，不利于人们的身体健康；二是管件连接的可靠性差，长期使用中可能会存在渗漏的隐患。这些局限性使在地暖市场中管的占有率逐年萎缩，取代它的是一种具有耐老化性更佳且健康环保、安全可靠的新型地暖管材——PE-RT管。中文名为耐高温聚乙烯管
