Specifications

13 5/8" Rotary BOP

13 5/8” – 1500psi/3000psi rotary BOP is a type of well control equipment used in underbalanced drilling.

The major parts include: shell, locking assembly, rotary assembly and drill pipe actuator assembly. They fall into two types: BOPs with single packing unit and double packing unit respectively.

Structural characters

It adopts double packing unit or single packing unit

The rotary dynamic sealing part adopts quick stripper cases

Bearing are lubricated by force.

The cooling system realizes circular cooling to the upper dynamic parts

It adopts modular designs
