相對(duì)于其他pp管材,pp-r管材的-優(yōu)點(diǎn)是既-了pp-h的低溫脆性,普陀區(qū)ppr水管件,又在較高溫度下(60℃)具有-的耐長期水壓能力,-是用于熱水管使 用時(shí),長期強(qiáng)度均較pp-h和pp-b好。
compared with other pp pipes, the outstanding advantage of pp-r pipe is that it not only improves the low temperature brittleness of pp-h,ppr水管管件, but also has good long-term water pressure resistance at higher temperature (60 ℃). espe-lly when it is used for hot water pipe,ppr水管件廠家, the long-term strength is better than pp-h&pp-b.
鋁塑管的連接,需要使用卡套式管件,時(shí)間久了,卡套管件,受其本身材質(zhì)與工作方式的影響,連接不夠緊密,容易出現(xiàn)漏水的情況。ppr管材之間一般采用熱熔焊接,當(dāng)需要與其它材質(zhì)的管道連接時(shí)如鋼制水管、銅制水管、熱水器等,采用具有內(nèi)、外絲口的銅制ppr管件連接。ppr管材與管材、管材與管件之間均采用熱熔焊接,焊接接口位置強(qiáng)度與管材一致,密封性優(yōu)良。
