ppr水管在连接时，嘉兴pvc管业，无旋转地把管端导入加热套管内，插入到所标志的---，同时无旋转地把管件推到加热管上，达到规定标志处。一般地可用心中默读数字法掌握加热时间，pvc管业厂家，或观察管件、管材的加热程度，当模头上出现一圈ppr热熔凸缘时，即可将管材、管件从模头上取下进行下道工序。
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.
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---。ppr管的管内很光滑，不容易出现水垢，影响水质的纯净。
ppr管的耐水性：
耐水管件的连接和防渗漏性能也是应该注意的。由于ppr管生产线经过对该管材特点的分析，设---产了的剥铝工具，将铝层及ppr外层剥离掉，pvc管业电话，同样可以采用热熔承插的方法进行连接，pvc管业加盟，消除了普通ppr管用铜管件连接容易渗漏的引患，---的是管道实现其耐水性能。
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.
