Ram

  • NL Rig Equipment of Houston has prepared a fact sheet illustrating and describing the new Shaffer Multi-Ram™ multiple-size rams.

    The new rams are designed to close and seal on drill pipe from 31,/, to 5 inches in diameter, making Multi-Ram rams especially useful in situations in which a tapered string is employed. These rams are said to save drilling time and costs because they make ram change-out unnecessary.

    The variable Multi-Ram fit is accomplished through the use of unique ram rubbers with moldedin steel segments. As hydraulic pressure increases, the segments move radially inward, decreasing the bore size and ensuring a reliable seal. In addition, the new rams use standard ram holders and r e t a i n i n g screws, which makes them interchangeable with regular rams in Shaffer blowout preventers.

    NL Rig Equipment/NL Industries, Inc. manufactures, sells and services drilling and production equipment worldwide for the oil industry.
