宿迁PVC排水管-PVC排水管加盟-Gafloon卡弗龙

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，PVC排水管咨询，影响PPR管价格的长期性能；对于PPR管的电熔连接，宿迁PVC排水管，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， and the process is random. In the process of hot melt push welding， 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.

PPR管参数

装修中，常听工人说4分管、6分管，自己却不知道是什么意思？其实这指的是管子的外径，4分管外径20mm，6分管外径25mm。选择哪种管，要看水管的外径来决定。管4分管，只能使用4分管。管是6分管，使用6分管、4分管都可以。另外，水管上也会标注20*2.8、25*4.2，前面的20、25就是指管子外径，而后面的2.8、4.2则指水管的壁厚。一般管壁越厚，PVC排水管电话，水管就越耐用。

Parameters of PPR tube

Decoration，PVC排水管加盟， often listen to workers say 4 in charge， 6 in charge， but do not know what it means? In fact， this refers to the outer diameter of the pipe. The outer diameter of 4 branch pipes is 20 mm， and that of 6 branch pipes is 25 mm. Which kind of pipe to choose depends on the outer diameter of the pipe. Only four branches can be used. The management is divided into 6 branches. It is OK to use 6 branches or 4 branches. In addition， 20 * 2.8 and 25 * 4.2 will also be marked on the water pipe. The front 20 and 25 refer to the outer diameter of the pipe， while the back 2.8 and 4.2 refer to the wall thickness of the water pipe. Generally， the thicker the pipe wall is， the more durable the water pipe is.

PPR管虽然熔焊简捷，但是在加热后，准确快速地把持管件的方向不容易掌握。因为管子和管件加热软化后，连接时间很短，***采暖常采用小管径的管子，只留有约3 - 4秒的时间，要想在这样短的时间里将管件（例如三通、弯头）矫正不容易。

Although the fusion welding of PPR pipe is simple， it is not easy to grasp the direction of pipe fitting accurately and quickly after heating. Because the connection time of pipes and fittings is very short after they are heated and softened， ***all diameter pipes are often used for independent heating， which only takes about 3-4 seconds. It is not easy to correct the fittings (such as tee and elbow) in such a short time.
