Description
Cross is a very important part of Malleable Iron pipe fittings. According to different characteristics, Malleable Iron cross can be divided into many different types.Straight cross, code 180. Malleable Iron is mainly used for cross connection of two pipes. It has four exports of the same caliber. Malleable Iron reducing cross, code 180r. The outlet diameters of the two opposite pipes are the same, but the outlet diameters of the crossed pipes are different.
Naming method: large caliber export is the first, and smaller caliber export is the second. For example, the two opposite outlets of the main pipe are 50, while the other two outlets are 25.Malleable Iron reducing cross is named as 50 * 25 reducing cross.Large cross at Malleable Iron side, code 180r. The diameter of the main pipe is different. The diameter of the side pipes on both sides is the same but smaller than that of the main pipe.It is mainly used for branch in the main road. The naming method is to start with the large diameter of the main pipe and arrange them in clockwise or anticlockwise order.

Technology
At present, in the production of Malleable Iron cross at home and abroad, most of them are modified by adding alloy containing a certain amount of modified elements into iron water.The operation process is similar to the spheroidizing treatment of nodular cast iron.The upper and lower limits of modified elements required by Malleable Iron Steel are very narrow and sensitive to the fluctuation of process factors, which is more difficult to control than spheroidizing treatment.
On the one hand, it is necessary to develop a suitable modified alloy, so that it has a larger range.On the other hand, measures are taken in the treatment process to make the process factors as stable as possible and the absorption rate of modified elements as high and uniform as possible.
Application
Malleable Iron Cross is suitable for rated working pressure of 1.6Mpa and working temperature of 200 ℃.Transport liquid, gas, such as water, oil, natural gas, gas, water vapor and other general pipeline connection.Malleable Iron Cross with nominal diameter of 10-100mm is pipeline connection, and its surface is painted, painted and hot galvanized.
