key feature:
1) Shape Generally, the BOP body is similar to a square, in the middle there is vertical bore through which the pipes
can pass and the ram cavities in which the ram move in the horizontal direction.
2)Connection types The three connection types are studded, flange, clamped top and bottom connections. The sizes
of flanges, bolts, clamps and ring grooves all conform to API standards.
(2) Features of Ram Structure and Application
For the double-face ram, the upper-face ram and lower-face of the ram are exactly symmetrical. For various drilling
tools with different sizes, it only need to replace the semi-annular rubber sealing ring and ram compact, the other parts
can be interchanged. The single-face ram can not be turned over; the shearing ram can shear the drilling tool in the hole
to seal off the well. The ram BOP with variable bore rams can be used for the sealing off the casing and drilling tools
of various sizes within a certain range.
