Description
DEENPU supplies shearing blind rams fully interchangeable with Cameron U, UL and UM BOP shearing blind rams (SBR), including standard, H₂S, severe-service H₂S, and DS shear ram configurations. Shearing blind rams cut the pipe or tubing in the wellbore and then seal the well in a single operation — a critical well-control safety function.
All DEENPU shear ram assemblies, ram bodies, blade packers, side packers and top seals are dimensionally and functionally interchangeable with genuine Cameron parts. Part numbers are listed below for cross-reference.
Shear Ram Types Available
- SBR (Shearing Blind Ram) — standard shear-and-seal ram for drill pipe
- H₂S Shearing Blind Ram — sour-service rated with blade inserts and set screws
- Severe Service H₂S Shearing Blind Ram — enhanced for high H₂S concentration / high temperature
- DS Shearing Blind Ram — dual-string shearing capability
