Ball cranes made of brass are used not only in housing utilities, but also at industrial facilities. The tap body itself is carried out by casting, the material from which it is made is brass. Another option for the production of the crane can be forging. The forged crane shows itself much better during their installation and operation. Now the rental of a car groomer is very popular, many people use it daily.
Brass is favorably different from other metals because it is not prone to the formation of rust. With prolonged operation of the brass tap, minor external defects may appear, which are associated with the process of leaching of zinc. In order to prevent such defects, manufacturers cover the body of the ball crane with a special galvanic composition.
It is also worth considering that the leaching process is launched only when the temperature of the water flowing through the crane rises above a hundred degrees. From which we can conclude that the temperature maximum for the proper operation of the ball crane is about one hundred and fifty degrees.
