1. Designed for well servicing, workover, and light drilling 2. Four ram, forged-steel body 3. API 16A Standards, NACE
Four ram blowout preventer can finish following operations:
1. When having a drill pipe, assembling corresponding pipe rams can seal off the annulus between the outside of the drill pipe and the well bore.
2. When having no pipe, assembling blind ram can close off.
3. When emergency, slip ram support tubing or prevent the tubing from stripping out and shear ram cut through the drill pipe. Then seal the well with blind ram.
4. When up or down in the emergency, slip ram clamp the pipe to prevent accident.
5. In the condition of shutting the well, four rams BOP can finish special operations such as restrict flow, blow out and so on.
