Single Plug Cementing Head
Product Description
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.
