Sphericals also provide positive pressure control for stripping drill pipes into and out of the hole.
Rubber core store glues big quantity,small friction resistance when switch pressure sealing ability.
Using hemisispherical head,no stress concentration phenomenon when under pressure,casing stress evenly,easy to tear open outfit.
Long-life sealing element provides positive seal after hundreads of tests to full working pressure.
Strong,simple construction-only five major,which simplifies maintenance.
Sealing element design provides long stripping life.
