| 弯头与弯管本质上的区别主要是在“头”和“管”上的区别，除此之外在制作工艺上也有很大的不同之处。 The essential difference between elbow and elbow is mainly the difference between "head" and "pipe". In addition, there are also great differences in manufacturing technology. 弯头是水暖安装中常用的一种连接用管件，用于管道拐弯处的连接，用来改变管道的方向。用于连接两根公称通径相同或者不同的管子，使管路作90°、45°、180°及各种度数的转弯。 Elbow is a kind of pipe fittings commonly used in plumbing installation. It is used to connect the bends of pipes and to change the direction of pipes. It is used to connect two pipes with the same or different nominal diameter, and make the pipes turn at 90 degree, 45 degree, 180 degree and various degrees. 下面简要介绍一下弯头与弯管在制作工艺上的区别： Following is a brief introduction of the differences between elbow and elbow in manufacturing process. 1.弯头相对弯管来说比较短。R=1倍到2倍的是弯头，再大的倍数就叫弯管。 1. Elbows are shorter than elbows. R = 1 to 2 times is the elbow, and the bigger one is the elbow. 2.冷弯管可以用现成的直管用弯管机弯制，一次性完工还不用二次防腐。但弯头要厂家定做，要做防腐，订货周期长。 2. The cold bending pipe can be bent by a ready-made straight pipe bender without secondary corrosion protection after one-time completion. But elbows need to be made to order by manufacturers, anti-corrosion and long order period. 3.弯头价格比弯管要高但是性价比却比弯管要高出很多，没有做防腐处理的弯管易损坏，但其因为价格便宜，在一些要求不是很高的工程使用非常多。所以介于弯头和弯管的性能和价格不一样选用时一定要注意。 3. Elbows are more expensive than elbows, but their cost performance is much higher than elbows. www.penquandiaosu.com.cnwww.hanbaiyulangan.cnwww.shidiaopixiu.cnwww.huganqii.cnElbows www.qinhuandaobanjia.cnwww.chengshidiaos.cnwithout anticorrosive treatment are easy to be damaged, but because of their low price, they are widely used in some projects with low requirements. Therefore, in the elbow and elbow performance and price is not the same choice, we must pay attention to. |
