  • 给水管道常用的管材都有哪些你知道吗?
  • 本站编辑:杭州康美塑化有限公司发布日期:2019-12-09 19:53 浏览次数:

   常用的给水管材有: PPR管、铜管、铝塑管、镀锌管、PVC管、薄壁不锈钢管、衬PVC不锈钢管。下面就让康美管业来为大家一一介绍。 

   1、PPR管:作为一种新型的水管材料,PPR管具有得天独厚的优势,卫生无毒,既可以用作冷水管,也可以用作热水管。

       优点:价格适中、性能稳定、耐热保温、耐腐蚀、内壁光滑不结垢、管道系统安全可靠,并不渗透,使用年限可达50年。

       缺点:但连接时需要专用工具 ,连接表面需加热 ,加热时间过长或承插口插入过度会造成水流堵塞。 

       2、铜管:是水管中的上等品,铜在化学活性排序中的序位很低 ,比氢还靠后 ,因而性能稳定 ,不易腐蚀。据有关资料介绍 ,铜能抑制细菌的生长 ,保持饮用水的清洁卫生。

       优点:强度高,性能稳定,可杀菌,且不易腐蚀。

       缺点:价格高、施工难度大,在寒冷的冬天,极易造成热量损耗,能源消耗大,使用成本高。 

       3、铝塑管:铝塑管曾经是市面上较为流行的一种管材,由于其质轻、耐用而且施工方便,其可弯曲性更适合在家装中使用。在装修理念比较新的广东和上海,铝塑管已经渐渐地没有了市场,属于被淘汰的产品。

       优点:价格比较便宜,可任意弯屈,表面光滑,施工方便。

       缺点:易老化,使用隐患多,使用年限短,实践证明,其管道连接处极易出现渗漏现象。 

       4、镀锌管:好久不用的水管,你突然打开竟发现流出的是“黄”水,以前老房子中镀锌铁管中极易发生这样的事情,这样的“黄”水对人体也是有危害的。从2000年起禁用镀锌管,目前新建小区的冷水管已经很少使用镀锌管了。

       优点:品种齐全,管件配套多。

       缺点:属于国家禁止使用的淘汰产品,易腐蚀生锈,导致水流不畅,极易造成水源的污染。 

    5、PVC管:实际上就是一种塑料管,接口处一般用胶粘接。因为其抗冻和耐热能力都不好,所以很难用作热水管;强度也不适用于水管的承压要求,所以冷水管也很少使用。大部分情况下,PVC管适用于电线管道和排污管道。另外,使PVC变得更柔软的化学添加剂酞,对人体内肾、肝、睾丸影响甚大,会导致癌症、肾损坏,所以不建议大家购买。

       优点:轻便,安装简易,成本低廉,也不易腐化。

       缺点:质量差的会很脆,易断裂,遇热也容易变形。 

       6、薄壁不锈钢管:薄壁不锈钢管耐腐蚀不易生锈,使用安全可靠抗冲击性强,热传导率相对较低。但不锈钢管的价格相对较高,另外在选择时应采用耐水中氯水中氯离子的不锈钢型号。薄壁不锈钢管的连接有焊接、螺纹、封压等方式。

       优点:不易氧化生锈,冲击性强,热传导较低。

       缺点:成本较高,应采用耐水中氯离子的不锈钢型号。 

       7、衬 PVC镀锌钢管:衬 PVC镀锌钢管兼有金属管材强度大、刚性好和塑料管材耐腐蚀的优点,同时也克服了两类材料的缺点。

       优点:管件配套多、规格齐全。

       缺点:管道内实际使用管径变小 ;对环境温度和介质温度变化大时 ,容易产生离层而导致管材质量下降。

       经过上述对康美给水管材管件分类优缺点的介绍,大家都知道怎么选择自己需要的管材了吗?想了解更多关于管材管件的资讯,请大家持续关注本公司官网。

Commonly used water supply pipe: PPR pipe, copper pipe, aluminum plastic pipe, galvanized pipe, PVC pipe, thin-walled stainless steel pipe, lined with PVC stainless steel pipe. Let kang mei tube industry introduce for everybody one by one below.

1, PPR tube: as a new water pipe material, PPR tube has unique advantages, non-toxic health, can be used as cold water pipe, can also be used as hot water pipe.

Advantages: moderate price, stable performance, heat and heat preservation, corrosion resistance, smooth inner wall, safe and reliable pipeline system, no penetration, service life can reach 50 years.

Disadvantages: but special tools are needed for connection, and the connection surface needs to be heated. Excessive heating time or excessive socket plug insertion will cause water flow blockage.

2, copper tube: it is the first-class product in the water pipe, the sequence of copper in the chemical activity sort is very low, than hydrogen is still behind, so the performance is stable, not easy to corrosion. According to relevant data, copper can inhibit the growth of bacteria, keep drinking water clean and sanitary.

Advantages: high strength, stable performance, sterilization, and not easy to corrosion.

Disadvantages: high price, difficult construction, in cold winter, easy to cause heat loss, energy consumption, high use cost.

3. Alumino-plastic pipe: alumino-plastic pipe was once a popular pipe material in the market. Due to its light weight, durability and convenient construction, its bendability is more suitable for use in home decoration. In decorating a concept to compare new guangdong and Shanghai, aluminous plastic tube already did not have the market gradually, belong to the product that is eliminated.

Advantage: the price is cheaper, can bend arbitrarily, the surface is smooth, construction is convenient.

Disadvantages: easy aging, hidden trouble, short service life, practice has proved that the pipe connection is prone to leakage.

4, galvanized pipe: for a long time without the water pipe, you suddenly open unexpectedly found that the outflow is "yellow" water, before the old house galvanized iron pipe in such a thing, such "yellow" water is also harmful to the human body. Since 2000, galvanized pipes have been banned. At present, cold water pipes in new residential areas have been rarely used galvanized pipes.

Advantages: a complete range of fittings, supporting more.

Disadvantages: belong to the national ban on the use of obsolete products, easy to corrosion and rust, resulting in poor water flow, easy to cause water pollution.

5, PVC pipe: in fact, it is a plastic pipe, the joint is generally with adhesive. Because its ability to resist freezing and heat is not good, so it is difficult to use as a hot water pipe; Strength is also not suitable for water pipe pressure requirements, so cold water pipe is rarely used. In most cases, PVC pipes are suitable for electrical wiring and sewage pipes. In addition, PVC become more soft chemical additives phthalide, on the human body kidney, liver, testicle impact is very big, will lead to cancer, kidney damage, so we are not recommended to buy.

Advantages: lightweight, easy to install, low cost, and not prone to corruption.

Disadvantages: poor quality will be very brittle, easy to break, when the heat is easy to deformation.

6, thin-walled stainless steel tube: thin-walled stainless steel tube corrosion resistance is not easy to rust, safe and reliable use of impact resistance, relatively low thermal conductivity. But the price of stainless steel tube is relatively higher, in addition should be used in the selection of water chlorine water chlorine ion stainless steel model. Thin - walled stainless steel pipe connection has welding, thread, sealing pressure and other methods.

Advantages: not easy oxidation rust, strong impact, low heat conduction.

Disadvantages: the cost is higher, should use water chloride ion resistant stainless steel model.

7, lined with PVC galvanized steel pipe: lined with PVC galvanized steel pipe not only has the advantages of high strength, good rigidity and corrosion resistance of plastic pipe, but also overcomes the disadvantages of the two kinds of materials.

Advantages: pipe fitting matching more, complete specifications.

Disadvantages: smaller pipe diameter in actual use; When the temperature of the environment and the temperature of the medium changes greatly, it is easy to produce separation and lead to the decline of the quality of the pipe.

After the above introduction to the advantages and disadvantages of kangmei water supply pipes and fittings classification, do you know how to choose the pipes you need? Want to know more about the tube fitting information, please continue to pay attention to the company's official website.
