铝合金衬塑复合管材由于是外层铝合金,内衬PPR塑料,因此是一种轻质刚性材。其外层铝合金在保障管道支撑作用不变的前提下,铝合金的应用和内衬食品级 PPR塑料可以最大程度降低管道本身重量带来的压力,因此可以保障管道既有金属管道的刚性支撑,又可以应用弹性管件的抗性。也就是说铝合金衬塑复合管材相比较传统金属管道更轻,同时因为摒弃了传统金属管道卡扣式的连接方式,因此管道可以保障在微动条件下的稳性。 Aluminum alloy lined plastic composite pipe is a kind of light rigid material because of its outer aluminum alloy and inner PPR plastic. The application of aluminium alloy and food-grade PPR plastics can reduce the pressure brought by the weight of pipeline to the greatest extent, so it can guarantee the rigid support of both metal pipeline and the resistance of elastic pipe fittings. That is to say, the aluminium alloy lined plastic composite pipe is lighter than the traditional metal pipe. At the same time, because the traditional metal pipe clamping connection mode is abandoned, the pipeline can guarantee the stability under fretting conditions. 金属管道本身由于自身过重,因此施工成本高,而传统的卡扣式连接由于也是刚性连接,因此如果遇到轻微地震等问题,极其容易出现安全隐患,造成管道破裂。最后由于传统金属管道是金属本身与水接触,水中存在大量离子,因此长时间使用容易腐蚀金属管道。不仅会造成管道承压能力等质量和寿命下降的问题,同时也会给饮用水的卫生级别造成安全患。 The construction cost of metal pipeline is high because of its own overweight, while the traditional snap-on connection is also rigid connection, so if there are some problems such as slight earthquake, it is extremely easy to appear hidden safety hazards and cause pipeline rupture. Finally, because the traditional metal pipeline is metal itself in contact with water, there are a large number of ions in the water, so it is easy to corrode the metal pipeline for a long time. Not only will the quality and life of pipelines decrease, but also the sanitary level of drinking water will cause safety hazards. |
