Tube for Perforating Gun

Tube for Perforating Gun
 
Tube for Perforating Gun is the main raw material for manufacturing various high-performance oil and gas well perforating guns. The tube for Perforating Gun not only withstands the high-speed impact of perforating bullets during perforating operations, but also bears the reverse impact of perforating bullet fragments on the pipe.

In this way, not only the impact toughness of the perforating barrel is very high, but also the yield strength is also very high to withstand high impact loads.
 
Uses
For manufacture of perforating gun body
 
Standard
