The difference between sanitary elbow and sanitary elbow

The difference between sanitary elbow and sanitary elbow, as the name suggests, is essentially the difference between "head" and "tube", but there is a big difference in the production process. The most basic difference is that elbows are shorter than elbows. R=1 to 2 times is a sanitary elbow, and the larger multiple is called a sanitary elbow. In the production process, the cold-formed pipe can be bent with a ready-made straight pipe with a pipe bending machine, and the one-time completion does not require secondary anti-corrosion. However, the elbow needs to be customized by the manufacturer, it needs to be anti-corrosion, and the order cycle is long. The price of elbows is higher than that of elbows, but the cost performance is much higher than that of elbows. It is well known that elbows without anti-corrosion treatment are easy to damage, but because of their cheap price, they are widely used in some projects that are not very demanding.
