ULTRA HIGH PRESSURE TUBE

Ultra-high Pressure Tube

It is made by increase the ratio of wall thickness to outside diameter, and adjust the mechanical properties to get the features obtaining ultra-high pressure resistance.

Ultra-high Pressure : 0.1  ~   0.37 ,    Work Pressure :10000 ~ 20000 Psi

Required Pressure :10000 ~ 60000 Psi
