铝塑管就是由铝和塑料结合而成的,它的内外两层都是塑料,中间部分是铝,所以说铝塑管同时具备了金属和塑料两种属性。但由于是两种不同的材质,它们的膨胀系数不同,所以铝塑管会出现热胀冷缩的现象,从而导致水管。而PPR管为单一材质,虽然具有低温脆性,但是相比铝塑管,对温度的变化更不敏感,更不易老化破损、更耐用。PPR管的管内很光滑,不容易出现水垢,影响水质的纯净。
PPR 管材与 PPR 塑件连接,是常见的连接方式,通常大家听到的,ppr 管材热熔连接,就是说的这种方式,我们经常见到的,直接连接,大多采用 PPR 管和直接塑件进行热熔连接,ppr 管材,与 PPR 嵌件伸缩节,可直接进行热熔承插连接。
PPR pipe and PPR plastic parts connection, is a common way of connection, usually you hear, PPR pipe hot-melt connection, that is to say, this way, we often see,宜昌PVC管业, direct connection, mostly using PPR pipe and direct plastic parts for hot-melt connection, PPR pipe,PVC管业电话, and PPR insert expansion joint, can be directly hot-melt socket connection.
PPR管施工后须经试压验收后方能封管和使用。PPR管安装主要采用热熔管件,熔接时间和压力不好掌握,工艺随机性较大,在热熔推接过程中易产生堆料从而减小通径,并使熔接处成为不规则的缺陷区,产生应力集中,影响PPR管价格的长期性能;对于PPR管的电熔连接,由于电熔丝主要采用促进PPR降解的铜,会加速PPR管的老化。
PPR pipe can be sealed and used only after pressure test and acceptance.The PPR pipe is mainly installed with hot-melt pipe fittings. The welding time and pressure are not well mastered,PVC管业厂家, and the process is random. In the process of hot melt push welding,PVC管业咨询, it is easy to generate stacking materials to reduce the diameter, and make the fusion joint become an irregular defect area, which produces stress concentration, which affects the long-term energy of price of PPR pipe; For the electric melting connection of PPR pipe, the aging of PPR pipe will be accelerated because copper is mainly used to promote the degradation of PPR.
