Structural features
For double-faced ram, both faces of the ram are symmetrical. For different sizes of drilling tools, only rubber seal semi-ring and ram briquetting need to be replaced, and other parts can be used interchangeably; single-faced ram is not reversible; shear ram can cut off wellhead drilling tools and fully seal wellhead; variable ram is used within certain limits to seal different sizes of drilling tools and annular tubes.
Not only the pipe rams and blind rams but also the variable bore ram and shear rams are available without any structure change.
