Description
DEENPU supplies pipe rams fully interchangeable with Cameron U, UL and UM BOP pipe rams. Cameron pipe rams are self-feeding and incorporate a large reservoir of packer rubber to ensure a long-lasting seal under all conditions. Ram packers lock into place and are not dislodged by well flow, and all are suitable for H₂S service per NACE MR-01-75. CAMRAM™ top seals are standard for all U, UL and UM BOP pipe rams from 7-1/16″ through 18-3/4″.
All DEENPU pipe rams, ram packers and top seals are dimensionally and functionally interchangeable with genuine Cameron parts. The standard “U” BOP pipe rams are interchangeable across U, UL and UM BOPs of the same bore size. Part numbers are listed below for cross-reference.
