镀锌管的作用和优点
The role and advantages of galvanized pipe
1、具有防腐耐磨的特点，让钢管使用寿命更长；
1, with anti-corrosion and wear-resistant characteristics, so that the service life of the steel pipe is longer.
2、可以对钢管进行的保护，通过加热后让钢管每一个部分都镀上了锌，凹凸处得到了保护；
2, the steel pipe can be fully protected. After heating, every part of the steel pipe is plated with zinc, and the concave and convex parts are protected.
3、钢管表面采用防锈处理更加的耐用，不甚于过快的氧化，不会在钢管上面形成白锈；
3. The surface of the steel pipe is more durable by rust treatment, not faster than oxidation, and will not form white rust on the steel pipe.
4、镀锌的钢管就是三九天也不会冻裂，特别适合北方天寒地冻的环境；
4, galvanized steel pipes will not freeze for 39 days, especially for the cold and frozen environment in the north.
5、由于已经在钢管外面已经镀上了锌，从而省去了在外面涂油或漆的时间，施工也更加方便。
5, since zinc has been plated outside the steel tube, the time for oil painting or paint is omitted, and the construction is more convenient.
