ppr管-Gafloon-顺义区ppr管

现在，一些小的宾馆或一些建筑物的部分商业、办公区域也需要用到采暖和生活热水，他们的热负荷或生活热水用量要比家庭大许多（即并联安装若干台燃气壁挂炉）；因此热水管的管径比较大，在与集分水器、隔离罐、控制附件等连接时需要用到法兰连接。

Now， some ***all hotels or some commercial and office areas of some buildings also need heating and domestic hot water， and their heat load or domestic hot water cost is much larger than that of families (that is， several gas-fired wall mounted boilers are installed in parallel); Therefore， the diameter of the hot water pipe is relatively large， and flange connection is needed when connecting with the water distributor， isolation tank， control accessories，顺义区ppr管， etc.

PPR水管连接?

PPR水管连接的方式主要采用的是热熔。在进行热熔连接前，要将管道的的两端上的尘土及污渍清除掉。在用熔接机加热管材的及管材的配件，ppr 管，当管材的极其的管件的热熔深度及时间达到一定的要求后，可进行管材的热熔焊接。?

The main connection mode of PPR water pipe is hot melting. Before the hot-melt connection， the dust and stains on both ends of the pipe should be removed. When the welding machine is used to heat pipes and pipe fittings， when the hot-melt profundity and time of pipes and pipe fittings meet certain requirements， the hot-melt welding of pipes can be carried out.

什么是低温脆性？低温脆性是指材料的冲击吸收功随温度降低而降低，ppr管，当试验温度低于Tk(韧脆临界转变温度)时，冲击吸收功明显下降，ppr管件，材料由韧性状态变为脆性状态，这种现象称为低温脆性。

What is low temperature brittleness? Low temperature brittleness means that the impact absorbed energy of material decreases with the decrease of temperature. When the test temperature is lower than TK (critical transition temperature of toughness and brittleness)， the impact absorbed energy decreases clears， and the material changes from ductile state to brittle state. This phenomenon is called low temperature brittleness.
