Our ram-type blowout preventers (BOPs) are in accordance with API 16A standards for low and high pressure applications. All components such as the ram block assemblies, pistons, body, pressure seals, flanged or studded end connections, and bonnets are remanufactured to API standards and are restored to a “like-new” condition.

1. Classified as per ram quantity: Single ram blowout preventer; Double ram blowout preventer; Triple ram blowout preventer;

2. Classified as per ram shape:

Blind Rams: The rubber sealing element is flat and can seal the wellbore when there is nothing in it

Pipe Rams: The sealing element is shaped to fit around a variety of tubulars, which include production tubing, drill pipe, drill collars, and casing that will seal off the wellbore around it

Variable Bore Rams: The sealing element is much more complex and allows for sealing around a particular range of pipe sizes

Shearing Blind Rams: The blade portion of the rams shears or cuts the drill pipe, and then a seal is obtained much like the blind ram
