Product Description
The ram BOP is designed to seal off the tubularannulus or the well. With the ram BOP in the closed position, such operations as circulating drilling fluid, re-leasing pressure and killing the well can be performedby means of the spool beneath the BOP or pipelinesconnected to outlet of the BOP body. Under specialcircumstances, the ram BOP can shear the pipe in thehole to seal off the well. If the ram BOP has variablebore rams, it can seal off the annular space betweenthe casing and the pipes whose sizes are at the mini-mum and maximum of the ram's range.
2, Structural Features
(1) Body Structure
a. Shape. The BOP has a body similar to squareshape, having a vertical bore through which the pipescan pass and ram cavities in which the rams move inthe horizontal direction.
b. Connection types. The BOP are offered withstudded, flanged and hubbed top and bottom connections. The sizes of flanges, bolts, clamps andring grooves all conform to API 16A.
(2) Ram structure
For dual-face ram, the upper face and lower faceof the ram are exactly symmetrical. Various drilling toolswith different sizes is only necessary to replace the semi-annular rubber sealing ring and ram compact, the oth-ers can be interchanged.
(3) Seal of Ram
The seal of the ram putting into effect of the pack-ing wellhead must depend on four seals. i.e. the sealbetween the top of the ram and housing, the seal be-tween the fore-end of the ram and the pipeline, the sealbetween the housing and the side-gate and the sealbetween piston rod and the side-gate.
(4) Locking Mechanism of Ram
The manual locking device depends on manpower torotate handwheel to close or lock the rams. It shall benoted that the manual locking device only can be usedto close rams. Be sure to make the manual locking de-vice return to the original position to unlock the ramsbefore opening the rams with hydraulic pressure.
Operating Requirements
(1) As blowout happens, full-enclosed ram BOP isable to pack off an empty well or semi-enclosed ram isable to pack off the drilling tool with the same size asthe ram. If long time of well close is necessary, the ramshould be locked up manually and a nameplate shouldbe provided for indication. The wheel is pulled to thestation prior to turned back at 1/4~1/2 circuit.
(2) Before opening rams, check whether the manual locking device is unlocked or not. Every time after open-ing rams, check whether rams are in the full open posi-tion or not in order to prevent pipes from damaging rams.
(3) Release pressure in the control manifold before opening or closing the door in order to prevent damageto O-Ring of the hinge. If the door is not in the full openposition or its bolts not installed well, it is not allowed toopen or close rams with hydraulic pressure.
