ppr水管在連接時，嘉興pvc管業(yè),，無旋轉(zhuǎn)地把管端導(dǎo)入加熱套管內(nèi)，插入到所標(biāo)志的---,，同時無旋轉(zhuǎn)地把管件推到加熱管上,，達到規(guī)定標(biāo)志處。一般地可用心中默讀數(shù)字法掌握加熱時間,，pvc管業(yè)廠家,，或觀察管件、管材的加熱程度,，當(dāng)模頭上出現(xiàn)一圈ppr熱熔凸緣時,，即可將管材、管件從模頭上取下進行下道工序,。
when the ppr water pipe is connected,， the pipe end is led into the heating sleeve without rotation&inserted to the marked depth. at the same time,， the pipe fitting is pushed onto the heating pipe without rotation to reach the specified mark. generally， the heating time can be mastered by reading numbers in heart,，/the heating degree of pipe fittings&pipes can be observed. when a circle of ppr hot-melt flange appears on the die head,， the pipe&pipe fittings can be removed from the die head for the next process.
鋁塑管就是由鋁和塑料結(jié)合而成的，它的內(nèi)外兩層都是塑料,，中間部分是鋁,，所以說鋁塑管同時具備了金屬和塑料兩種屬性。但由于是兩種不同的材質(zhì),，它們的膨脹系數(shù)不同,，所以鋁塑管會出現(xiàn)熱脹冷縮的現(xiàn)象，從而導(dǎo)致水管,。而ppr管為單一材質(zhì),，雖然具有低溫脆性，但是相比鋁塑管,，對溫度的變化更不敏感,，更不易老化破損、更---,。ppr管的管內(nèi)很光滑,，不容易出現(xiàn)水垢，影響水質(zhì)的純凈,。
ppr管的耐水性：
耐水管件的連接和防滲漏性能也是應(yīng)該注意的,。由于ppr管生產(chǎn)線經(jīng)過對該管材特點的分析，設(shè)---產(chǎn)了的剝鋁工具,，將鋁層及ppr外層剝離掉,，pvc管業(yè)電話，同樣可以采用熱熔承插的方法進行連接,，pvc管業(yè)加盟,，消除了普通ppr管用銅管件連接容易滲漏的引患，---的是管道實現(xiàn)其耐水性能,。
water resistance of ppr pipe:the connection&leakage resistance of water resistant pipe fittings should also be paid attention to. because of the ---ysis of the characteristics of the pipe,， the production of the stripping tool is designed&produced. the aluminum layer&the outer layer of ppr can be separated. the hot melt socket can be used to connect the pipe. the common copper pipe used in ppr pipe is easy to leak，&the better is to realize the water resistance of the pipe.
