‘U’ type Ram Blowout preventers
‘U’ type blowout preventers are the most widely used Ram-type BOP in the world. Without lightweight and lower profile, reliability is always the first priority during the design and manufacturing of BL ‘U’ type BOPs. It is designed so that hydraulic pressure opens and closes the bonnets thus fulfill the easy & quick ram change-out. All parts of our ‘U’ BOPs are matched to original OEM design which can reduce the maintenance time for customers since they can pick up any seal kits from local supplier.
‘U’ type Ram BOP features:
-Bore size range: 7 1/16” - 21 1/4”
-Working Pressure: 2000psi - 15000psi
-Hydraulically Bonnet opening type
-Forged Body by 4130 Material
- Internal H2S trim is standard
-Wide range pipe ram available and interchangeable with OEM
-Shearing Ram available and interchangeable with OEM
-VBR Ram available and interchangeable with OEM
-Large Bore Shear Bonnets available and interchangeable with OEM
-Boosters available and interchangeable with OEM
