Detailed
API 16A Annular BOP
| |
| |
● Packing element is spherical or tapered type with massive storage volume, low operation pressure and excellent sealing function; ● Bonnet is hemispherical-shaped, so there is no stress concentration on bonnet whenever bearing the pressure. ● Bonnet and body are connected by a wedge block, so the pressure is evenly distributed; ● Packing element is interchangeable with similar overseas products; ● Use observation hole to check the life span of the packing element; ● Piston is set in low position to have a shorter moving distance; Use wear ring on piston. |
