The difference between elbow and elbow, elbow and elbow how to choose

Bends and elbows are used to change the direction of the pipeline pipe fittings products, in the major engineering in the use of the number of elbows is much larger than the elbow.

An elbow is a tube that has been properly bent to fit the use. Bends are generally manufactured according to specific needs. Compared with elbows, elbows are longer. If R is higher than 2 times, it is elbows. If R = 1 to 2 times, it belongs to elbows. The following is the appearance of elbows and elbows.

A: the production process is different

In terms of the manufacturing process of bends, cold bends can be bent and formed directly with a pipe bender. Bends can be produced and manufactured at one time without secondary anti-corrosion. However, bends should be customized by manufacturers, anti-corrosion is required, and the order period is long.

Second: the price is different

The price of the elbow is lower than that of the elbow, but the cost performance is much lower than that of the elbow. If the elbow is not treated with anti-corrosion treatment, it is easy to damage. As we all know, I will not say it, but it is used very much in some projects with low requirements because of its low price.

Third: the scope of application is different

Elbow bends can be used in open areas, only considering the cost, cold bending of elbows can be done, elbows need hot bending, of course, the cost of elbows is high. Sometimes narrow sections must use elbows, such as stone section trench, because the radius of curvature of the elbow is small, generally 6D, and the elbow is 40D. Engineering construction site construction site, the use of elbow or elbow, not only to consider the price of elbow and elbow quality, but also consider where to use, so as to choose elbow or elbow.
