'Bolt cover' type Annular BOP features space saving design,low operating pressure and compact structure thus makes it ideal to use where space is priority. It can seal off telly, drill pipe,tool joint,drill collar,casing&tubing,wireline or any other shape of drilling tools. Stripping of pipe,tubing,and wireline through the packing element can also be accomplished at lower pressure.Awide range of sizes both in bore(from 7 1/16" to 20 3/4")and working pressure(from 3000pso up to 10000psi)are available to suit any work applications.
