銅vs 聚氯乙烯 vs鍍鋅-哪種管子效果最好？
有些人拔出頭髮來決定購買哪些管道來進行室內水暖工程。為了使您更輕鬆，您需要知道內部管道的材料。以下列出了三種最常見的室內管道類型：
銅
鍍鋅的
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 銅, 鍍鋅的, 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 銅
銅 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. 銅 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. 銅 pipes also are more prone to withstand earthquakes.
The disadvantage of 銅 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.
鍍鋅的優缺點
鍍鋅是用鋅塗覆金屬的過程。結果，鍍鋅鋼和鍍鋅鐵優於舊的鋼管。鋅塗層有助於防止腐蝕和管線中的礦物沉積。但是，這些管道更適合大型建築項目。污水或農業灌溉用於鍍鋅管。
鍍鋅管的缺點是含鉛迅速並腐蝕。鍍鋅管道的平均壽命為40年。今天，大多數房屋已經更換了鍍鋅銅管，因為沈積物積聚在輸水管線內，並導致水流的極端阻塞。
PVC的優缺點
與鍍鋅鋼和銅相比，PCV具有許多優勢。首先，這是三個中最輕的。這樣便於安裝。另外，它是三種類型中最便宜的。另外，它可以承受比銅更高的水壓。此外，PCV不導電，不會生鏽並且不利於冷凝。另外，當水壓高時，PCV安靜。另一個優點是PCV可以放置在混凝土板下面，而不會與混凝土反應。另外，它是自絕緣的。這就是為什麼他可以在更高溫度下處理水的原因。
儘管它可以承受熱水溫度，但阻燃性較差。這是PCV的最大缺點之一。另外，軟管通常僅在½英寸至2英寸的範圍內可用。這使它們非常不靈活。另外，PCV密封件非常笨重。結果，PVC管道不能像銅一樣緊密地安裝在狹窄的地方。另外，PCV包含對環境有害的揮發性化合物。另外，有些人抱怨PVC管給水帶來一點塑料味。
以上對每種類型的內部管道材料的優缺點的描述並非完全排斥。對於任何想要更換房屋管道的人進行研究都是明智的。許多因素決定了用於管道工程的管道材料的選擇。
另外，一個人應該知道銅和鍍鋅鋼不能連接在一起。原因是兩者都可以引起化學反應。最好在您的房屋中放一種軟管。最重要的是，無論您選擇使用哪種管道，請記住，最好只用一種管道材料來完成整個項目。例外情況是，如果在水槽或馬桶後部增加一條短軟管。除此之外，最好使用所有管道。
