The design and manufacture at Annular BOP is according to API Spec 10A standard
Packing element is spherical or tapered type with massive
storage volume low operation pressure and excellent sealing
function. Bonnet is her hemispherical-shaped, so there is
no stress concentrator on bonnet whenever bearing the
pressre. 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 the packing element
Piston is set in low position to have shorter moving distance
Use wear ring on piston.
RAM type BOP
The design and manufacture of S-shaped Ram BOP is according to API Spec 161A standard. S shaped RAM BOP can be equipped with rams of various sizes.
-Body and side door are made at alloy steel; Use sale rings assembly
to improve sealing of side door.
-Use floating type ram. Front ram rubber is separated from top ram
rubber, making It more reliable in sealing and easier to change.
-Use bluried oil way inside body. Loading hinge is separated from hydraulic
-Compact hinge structure makes it easy to assemble and disassemble
-Use arc-shaped body chamber with four round corners as transition
section to reduce stress pack value ,whenever bearing the pressure
-Ram cavity can be fitted with ram assembly of same type BOP
-Flange grooves are stainless steel lined
