Reducing nipples is a special kind of nipples, which is used to connect two different sizes of internal thread pipe fittings. For example, 1''x1/2''means that the diameter of two internal threads to be connected is 1''and 1/2'' respectively, so as to realize the increase or decrease of pipe size.

When using reducing nipples, we should pay attention to the difference of pressure due to the change of pipe size. In the process of using, we should pay attention to the damage to the pipe due to the different changes of pressure, so as to avoid the use problems, especially in some high-pressure gas transmission projects.

Jianzhi reducing nipples is made of malleable cast iron, which can withstand the working pressure of 2.5MPa. At the same time, it has good performance in the working temperature from minus 20℃to above 200℃. Therefore, we can use Jianzhi to reduce nipples safely.
