Cement Head (Double Plug Cementing Head, Single Plug Cement Head, Drill Pipe Cement Head)
Cement Head (Double Plug Cementing Head, Single Plug Cement Head, Drill Pipe Cement Head) is a kind of device fitted to the top joint of a casing string to hold a cement plug before it is pumped down the casing during the cementing operation, which is manufactured from solid forged rounds of alloy steels AISI 4130/4140/ 4145 or equivalent material and are fully heat treated.
Cement Head (Double Plug Cementing Head, Single Plug Cement Head, Drill Pipe Cement Head) are used for cementing the annular space between casing and bore hole during 2nd stage of well construction cycle. In most operations, a bottom plug is launched before the spacer or cement slurry. The top plug is released from the cement head after the spacer fluid. Most cement heads can hold both the top and bottom plugs. A manifold incorporated into the cement head assembly allows connection of a fluid circulation line.
