Structure Features:
Body and side door are made of alloy steel.
Use seal 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 buried oil way inside body. Loading hinge is separated from hydraulic hinge.
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 peak value whenever bearing the pressure.
Ram cavity can be fitted with ram assembly of same type BOP made abroad.
Flange grooves are stainless steel lined.
