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
