Characteristics of Spherical BOP
Solid, reliable core sealant: in hundreds of trials under the rated working pressure, can provide a reliable seal.
Strong and simple structure: the five major parts.
Compact body design, saving space: The ring height is only 80% of BOP to 85%.
Hydraulic system is simple and easy to operate: just connect two hydraulic connectors.
Wear rings and moving parts to avoid the gold on the metal contact, to maximize extended service time.
Working conditions for H2S: H2S standard for BOP internal conditions, and simple replacement of bolts and makes the suspension of its external conditions for H2S.
Special light-type blowout preventer can be lifted by helicopter.
Operation and maintenance simple and convenient. Replace rubber core slurry into the hydraulic system will not allow.
Steel reinforced seals, worn over the rubber, will not form a seal.
Actually plastic core design may be extended from the drilling servic
