Bop Exchanged with Hrsb Spare Part

Ocean drilling BOP(The rig) Product features:
Two kinds of locking systen could be chosen:the manual locking system and the automatic hydaulic locking system
Not only the pipe rams and blind rams but aslo the variable bore rams and shear rams are available without any structure change
It is easy and convenient on-site to open the bonners by hydraulic pressure
The outlets on the both sides of the body make the operation on site flexible
The pressurized self-sealing sealing mechanism is used between the body and bonnets,so it is not necessary to apply too much pretightening force to secure the reliability of sealing
It is 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
Matched-manufacturing is not necessary for the bonnets and body,so the diserepancy could be eliminated by thestructure.And it is convenient for the maintenance in the future
According to the latest API Spec 16A standard
According to the latest API Spec Q1 , quality standard of IOS9001 and NACE-MR-01-75 ,H2st Trim
According to user requirements and the use of environmental can choose casting or forging.
The added wear-belts to the original design can prevent and improve the Cylinder-grinding because of unbalanced loading
Screws connection type is convenient for assmebly/disassenbling and exchange for packing unies
Optimize the bop control performance, a series of problems are solved such as ocean drilling platform, the space is little and so on.
