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,PVC管业加工,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,淮安PVC管业,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 small from the flange edge, less than 5mm. When the bolts are tightened,PVC管业咨询, it is easy to make the flange edge.
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,PVC管业品牌,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 have the characteristics of low temperature brittleness? It is obtained by random copolymerization of monomer and a small 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.![]()
ppr 管材与钢管法兰连接
大口径的 ppr 管材,比如DN 110以上,可以通过法兰与钢管进行机械连接,只需要将法兰上的螺丝拧紧即可。
Flange connection of PPR pipe and steel pipeLarge diameter PPR pipes, such as DN 110 or above, can be mechanically connected with the steel pipe through the flange, and only need to tighten the screws on the flange.
