Description
'U' type blowout preventers are the most widely used Ram-type BOP in the world. Without a lightweight and lower profile, reliability is always the priority during design and manufacturing. It is designed so that hydraulic pressure opens and closes the bonnets thus fulfilling the easy & quick ram change-out. All parts of our 'U' type BOP are matched to the original OEM design which can reduce the maintenance time for customers since they can pick up any seal kits from a local supplier.
