由于那些普通的(未添加其他的材质的)PPR管的刚性并不是很好的,明装ppr水管道会发生变形的情况,造成不美观的现象,而且还不具有阻氧的能力,一些生产厂家在PPR水管的外面加了一层铝皮(称之为稳态管)。ppr水管在熔焊前,PPR水管,需要用的剥皮工具将管端插入到管件的那一段铝皮剥去,ppr水管品牌,其余的连接操作步骤和注意事项与普通PPR管一样。

PPR管为什么会有低温脆性的特点?它是由单体和少量乙烯单体在加热、加压和催化剂作用下无规共聚得到的。乙烯单体随机地分布到长链中,北京ppr水管,其中乙烯单体一般控制在3-5%之间。乙烯含量和乙烯与的聚合方式决定了其具有低温脆性的特点。
Why does PPR pipe h***e the characteristics of low temperature brittleness? It is obtained by random copolymerization of monomer and a ***all amount of ethylene monomer under heating, pressure and catalyst. Ethylene monomer is randomly distributed in long chain, and ethylene monomer is generally controlled between 3-5%. The content of ethylene and the polymerization of ethylene determine its low temperature brittleness.
目前,法兰连接中大的问题主要是法兰本身不合格和法兰连接不合格。
现在市场上销售的一些法兰存在的质量问题有:
①法兰的钢材不合格,耐压强度较低,在使用若干个月或若干个年后,出现渗水。
②法兰的螺栓孔外缘距法兰的边缘太小,小于5mm,在螺栓紧固时,易使法兰边缘。
At present, the major problems in flange connection are the unqualified flange itself and the flange connection is unqualified.
Some of the quality problems of the flange sold in the market are as follows:
① The flange steel is unqualified and the pressure resistance is low. After several months or years of use, water seepage occurs.
② The outer edge of bolt hole of flange is too ***all from the flange edge, less than 5mm. When the bolts are tightened, it is easy to make the flange edge.
