API Blowout Preventer Equipment Coiled Tubing BOP Model 4
1/16"-10000psi
Coiled tubing BOP is the key components for well control device,
used in coiled tubing operation, effectively prevent the blowout
accident, implement safety construction. Is mainly composed of the
following two parts:
Coiled tubing operation BOP stack
● The BOP box adopts the side door type, simple and convenient
replacing rubber core, even the coiled tubing is in operation, and
rubber core can be replaced.
● With double cylinder structure, the use of pressure to seal and
reliable sealing, long service life and control low pressure.
● Original created side door lock structure, easy to use, stable
performance.
Four Ram coiled tubing BOP
● BOP with full sealing ram, shear ram, slip ram and half seal ram.
● Slip ram using removable structure design, the unique design of
tooth to reduce the harm of coiled tubing.
● Switch oil interface for fast plug connector, easy to operate,
and it is equipped with protection, safe and reliable.
