复合管的主要材料是各类金属和一些塑料复合材料，常见的有铝塑复合管、钢塑复合管，与一般塑料管相比同样具有重量轻易加工的特点，多种原料的加入会是它更具有拉伸性，内壁很光滑，阻力小不易结垢，稳定性好不易被腐蚀损坏，寿命长，不易损坏。可以采用多种方式组装：卡扣式电熔式都是可以的，方便快捷。但是像一些钢塑复合管会因为打孔原因失去稳定性，不耐压力，高压环境下可能会出现局部爆裂的情况。
The main materials of the composite pipe are all kinds of metal and some plastic composite materials. The common ones are aluminum-plastic composite pipe and steel plastic composite pipe. Compared with the general plastic pipe, they are also easy to process by weight. The addition of various raw materials will make it more tensile, with smooth inner wall, small resistance and not easy to scale, and the stability is not easy to be damaged by corrosion, long service life and not easy to damage. It can be assembled in a variety of ways: snap on type electric fusion type is available, convenient and quick. However, some steel plastic composite pipes will lose stability and pressure resistance due to drilling, and local burst may occur under high pressure environment.
