Union tail is part of union, to be used for accessory replacement. Jianzhi union tail has high standard level, it can be used on our Jianzhi pipe unions without any problems.
The best mechanical properties of the material：KTH330-08 malleable cast iron. All standards exceed international regulations
Our pipe fittings ensure high quality from the raw material.
We use electric furnace for melting, and its stability can ensure 100% qualified material.
And the high quality helps our customers win the market.
After casting, the fittings are specially kept at a temperature of 95 ° C, i.e. slow and uniform cooling occurs.
This leads to a decrease in internal stresses and an increase in tensile strength, so pipe fittings are not prone to breakage.
The pipe thus obtains better plasticity and can be used in high pressure and high temperature environments.
