Product Details

Design and Construction

All Ram BOPs were constructed from high-strength alloy steel, with all pressure-containing components subjected to refined forging and strict heat treatment for maximum durability and resistance to cracking or inclusions.

Extended ram chamber runway design minimizes stress concentration, ensuring long service life under demanding operating conditions.

Hydraulic systems operate both bonnet and ram movements through a streamlined single-line system, enabling efficient and reliable operation.

Key Features

Pressure-energized rams with hydraulically actuated bonnets for rapid and secure ram replacement

Manual locking screws included as standard

Optional hydraulic locking devices for safe remote operation

H2S-resistant internal components for sour service environments

Variable Bore Rams (VBRs) compatible and interchangeable with leading OEM designs

Large Bore Shear Bonnets engineered for heavy-duty operations, OEM interchangeable

Ram boosters available and OEM interchangeable

Seal kits fully interchangeable with OEM standards for simplified maintenance and local sourcing

Advantages

Field-proven reliability Designed with safety and durability as the top priority, ensuring dependable well control in the harshest environments.

Operational efficiency Hydraulically opening bonnets allow for quick and easy ram change-outs, reducing non-productive time.

OEM interchangeability All critical components and consumables match OEM specifications, lowering maintenance costs and improving spare parts availability.
