同种规格的PPR热水管壁厚要比冷水管的厚，简单举例：D25×2.3 D25×2.8 D25×3.5 D25×4.2 这里列举的是外径为25MM的PPR管所对应的四种不同规格，前面两种为冷水管，后面两种为热水管，因此可以非常明显的看出，ppr 管，冷水管的壁厚要小于热水管。
The wall thickness of PPR hot water pipe of the same specification is thicker than that of cold water pipe. Simple example: D25 × 2.3 D25 × 2.8 D25 × 3.5 D25 × 4.2 here are four different norms of PPR pipe with outer diameter of 25 mm. The first two are cold water pipes and the latter two are hot water pipes. Therefore， it is very clear that the wall thickness of cold water pipe is ***aller than that of hot water pipe.
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，ppr管件，使用6分管、4分管都可以。另外，昌平区ppr管，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， 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.
