Casting ram blowout preventer

> Not only the pipe rams and blind rams but also the variable bore ram and shear rams are available without any structure change.
> Matched-manufacturing isn't necessary for the bonnets and body,so the discrepancy could be eliminated by the structure. And it's convenient for the maintenance in the future.
> The outlets on the both sides of the body make the operation on site flexible.
> Three kinds of locking system could be chosen:the internal manual locking system,the outside manual locking system and the automatic hydraulic locking system.
> The pressurized self-sealing sealing mechanism is used between the body and bonnets,so it's not necessary to apply too much pretightening force to secure the reliability of sealing.
> it's very convenient to lift and transport the BOPs with the four lifting rods.
> The new sealing mechanism of ram shaft secures the sealing reliability under the high pressure.
> The ring grooves of flanges are all lined with the corrosion resistant alloy.
