铜vs 聚氯乙烯 vs镀锌-哪种管子效果最好？
有些人拔出头发来决定购买哪些管道来进行室内水暖工程。为了使您更轻松，您需要知道内部管道的材料。以下列出了三种最常见的室内管道类型：
铜
镀锌的
聚氯乙烯
Now that you know that the main three types of indoor plumbing pipes are made of, you can analyze each type. Listed below are the advantages and disadvantages of 铜, 镀锌的, and 聚氯乙烯. You can decide for yourself which is the best as you explore the advantages and disadvantages of each kind listed below.
Advantages and disadvantages of 铜
铜 is used most often in houses today, and is preferred by homeowners. The reason why, is because copper pipes increase the value of the home. Furthermore, they are safer than galvanized pipes because they do not contain led. Also, copper pipes are more form fitting than PCV pipe. 铜 pipes are smaller in diameter and can be used in tight places. Also, they are biostatic, which means that copper inhibits bacteria growth. Therefore the water is safer to drink. In addition, the insides of pipe to not have as much mineral buildup as galvanized pipes do. Also, they are more resistant to flame than PCV pipes. 铜 pipes also are more prone to withstand earthquakes.
The disadvantage of 铜 pipes is that they sometimes fail when water temperature is above 180 degrees. Furthermore, condensation often forms inside the pipes. When this condensation freezes, it blocks water flow. Another disadvantage is that coppers pipes cause water to have a slight metallic taste. Also, copper pipes are more costly to repair and install than PCV pipes.
镀锌的优缺点
镀锌是用锌涂覆金属的过程。结果，镀锌钢和镀锌铁优于旧的钢管。锌涂层有助于防止腐蚀和管线中的矿物沉积。但是，这些管道更适合大型建筑项目。污水或农业灌溉用于镀锌管。
镀锌管的缺点是含铅迅速并腐蚀。镀锌管道的平均寿命为40年。今天，大多数房屋已经更换了镀锌铜管，因为沉积物积聚在输水管线内，并导致水流的极端阻塞。
PVC的优缺点
与镀锌钢和铜相比，PCV具有许多优势。首先，这是三个中最轻的。这样便于安装。另外，它是三种类型中最便宜的。另外，它可以承受比铜更高的水压。此外，PCV不导电，不会生锈并且不利于冷凝。另外，当水压高时，PCV安静。另一个优点是PCV可以放置在混凝土板下面，而不会与混凝土反应。另外，它是自绝缘的。这就是为什么他可以在更高温度下处理水的原因。
尽管它可以承受热水温度，但阻燃性较差。这是PCV的最大缺点之一。另外，软管通常仅在½英寸至2英寸的范围内可用。这使它们非常不灵活。另外，PCV密封件非常笨重。结果，PVC管道不能像铜一样紧密地安装在狭窄的地方。另外，PCV包含对环境有害的挥发性化合物。另外，有些人抱怨PVC管给水带来一点塑料味。
以上对每种类型的内部管道材料的优缺点的描述并非完全排斥。对于任何想要更换房屋管道的人进行研究都是明智的。许多因素决定了用于管道工程的管道材料的选择。
另外，一个人应该知道铜和镀锌钢不能连接在一起。原因是两者都可以引起化学反应。最好在您的房屋中放一种软管。最重要的是，无论您选择使用哪种管道，请记住，最好只用一种管道材料来完成整个项目。例外情况是，如果在水槽或马桶后部增加一条短软管。除此之外，最好使用所有管道。
