管材管道在使用过程中热胀冷缩现象也是不可避免的。选自耐水性材料的PPR管道刚性增强，水平布管时不易下垂，增加了管线的美观，管道的弯曲回弹性得到提高，在高温下时仍保持外形的稳定。
The phenomenon of heat expansion and cold contraction is inevitable in the use of pipe. The PPR pipe selected from water-resistant material has stronger rigidity， and it is not easy to sag during horizontal pipe laying，ppr管件批发， which increases the appearance of the pipeline， improves the bending resilience of the pipeline， and maintains the stability of the shape at high temperature.
ppr管与铜丝件接头连接
PPR管材，与内丝三通、内丝弯头、外丝直接、铜活接等同铜丝件接头的PPR一端，进行热熔连接。
铜丝件的外丝、内丝一端，再与内丝、外丝部件进行机械连接。
Connection between PPR tube and copper wire connector
PPR pipe is hot-melt connected with the PPR end of copper wire joint，ppr管材管件， such as inner wire tee， inner wire elbow， outer wire direct and copper Union.
One end of the outer wire and the inner wire of the copper wire parts is mechanically connected with the inner wire and the outer wire parts.
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，ppr管件，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，水管就越耐用。
Parameters of PPR tube
Decoration， often listen to workers say 4 in charge， 6 in charge，ppr管件名称， 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.
