Ram BOP

PRODUCTS

Ram BOP is a field-proven product that is designed for a variety of operations, from overhaul to high pressure, critical maintenance operations to onshore drilling and subsea maintenance. The ram BOP preventer consists of the following elements: cast steel body, die grooves, hydraulic cylinder assemblies, dies, die rod, die rod seal, indicator system, etc.

The dimensions of the ram BOP upper, lower and outlet nozzles are in accordance with the specification for oil and gas drilling equipment according to the requirements of API 16A. Made of high-strength alloy steel, the parts working under pressure (such as the ram BOP housing, cover, etc.) are formed through external refining and proper heat treatment, preventing the ingress of harmful chemical components and non-metallic inclusions strictly from the materials and ensuring safety and reliability of the spot preventer. The piston chamber of the hull uses a long runway to reduce stress concentration. Both the hood switch and the piston switch are actuated by hydraulic pressure and share the same oil line. The cap uses the same oil line and piston opening and closing operation. In addition, the lid uses the same oil line and plunger closing and opening operation.

Ram BOP has 3 types: single-ram BOP, double-ram BOP and triple-ram BOP. The double-ram BOP can be closed with a manual control wheel, but it is not possible to open the dies manually due to the fact that the screw connection is only one-sided. As a rule, the BOP unit includes a working BOP with tube dies and a backup BOP with blind dies.
