As a manufacturer and a supplier we produce cementing tools since 1997, and now we have almost 400 workers, the products cover cementing head/plug, stage collar, float equipment, centralizer and so on.Please contact me if you have need, and my email is Maggie@pyzs-group.com, WgatsApp is +8613939319501 Cement head is a 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. In most operations, a bottom plug is launched before the spacer of cement slurry. The top plug is released form 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.
