Zirconium Seamless Tubing is a type of metal with strong corrosion resistance, which is suitable for equipment with chemical corrosion resistance. Its acid resistance is better than that of titanium and other steels, and similar to that of tantalum. Zirconium is also stable in alkaline solution. It is widely used in tube heat exchanger, coil-heat exchanger, serpentine tube heat exchanger, condenser, evaporator, pipe and other heat exchange equipment.

Standard Specification
Zirconium Seamless Tubing APPLICATIONS
The processing specification has a sensitive influence on the performance of the product. In particular, the cold processing and heat treatment process before the finished product should be controlled to meet the requirements of use.
The dimensional accuracy and surface quality of the pipe are required to be high. Therefore, the process equipment should have good precision, and the design and manufacture of the die should be advanced and reasonable.
