Cementing Head is designed to hold a cementing plug before it is pumped down the casing during the cementing operation. 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. A manifold incorporated into the cement head assembly allows connection of a fluid circulation line.
Double plugs cementing head is special tool for pumping slurry and releasing plug. It can couple with two plugs simultaneously,and makes the drilling fluid fill into casing in turn and quickly. This can simplify the cementing operation, prevent cement pollution.
