Ram BOP

The ram BOP is an integral part of well control equipment,featuring flexible closings and openings,easy operation,safe service and simple maintenance.

Application

The ram BOP is designed to seal off the tubular annulus or the well.With the ram BOP in the closed position,such operations as circulating drilling fluid,releasing pressure and killing the well can be performed by means of the spool beneath the BOP or pipelines connected to outlet of the BOP body.Under special circumstances,the ram BOP can shear the pipe in the hole to seal off the well.If the ram BOP has variable bore rams,it can seal off the annular space between the casing and the pipes whose sizes are at the minimum and maximum of the ram’s range.

Structural Feature

Body Structure

1. Shape

The BOP has a body similar to square shape,having a vertical bore through which the pipes can pass and ram cavities in which the rams move in the horizontal direction

1. Connection Types

The BOP are offered with studded,flanged and hubbed top and bottom connections.The sizes of flanges,bolts,clamps and ring grooves all comform to API 16A.

Ram Structure

For dual-face ram,the upper face and lower face of the ram are exactly symmetrical.Various drilling tools with different sizes is only necessary to replace the semiannular rubber sealing ring and ram compact,the others can be interchanged;

Single-face ram is unable to be re-used upsidedown;

Shear ram is able to cut the drilling tool of the wellhead off and fully pack off the wellhead;

Reducing ram is applicable for the seals for various drilling tools with different sizes and casings

in certain range.

Seal of Ram

The seal of the ram putting into effect of the packing wellhead must depend on four seals,i.e.the seal between the top of the ram and housing,the seal between the fore-end of the ram and the pipeline,the seal between the hosing and the side-gate and the seal between piston rod and the side-gate.

Locking Mechanism o Ram

The manual locking device depends on manpower to rotate handwheel to close or lock the rams.It shall be noted that the manual locking device only can be used to close rams.Be sure to make the manual locking device return to the original position to unlock the rams before opening the rams with hydraulic pressure.
