FH35-35 Drilling Shaffer type BOP for sale

API16A annular blowout preventer/BOP installation could consist of both annular and ram type BOPs assembled into a stack. Also, there can be a kill line valve and a choke line valve. The choke line valve is used to redirect the mud from the well bore to the choke manifold during a kick. The kill line valve is used to direct drilling fluid to the BOP during a kick. Annular BOPs are designed to form a seal in the annular space between the drill pipe and the wellbore and are usually mounted at the top of the BOP stack.

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