API hydraulic kill manifold 1. Application In case of increase in well head pressure, the manifold can provide a means of pumping heavy drilling fluid into the well to balance bottom hole pressure so that well kick and blowout can be prevented. In this case, by using blow down lines connected to the kill manifold, the increasing well head pressure also can be released directly for bottom hole pressure release, or water and extinguishing agent can be injected into the well by means of the kill manifold. The check valves on the kill manifold only allow injection of kill fluid or other fluids into the well bore through themselves, but do not allow any backflow so as to perform the kill operation or other operations.   2. Structure The manifold consists of check valves, gate vales, pressure gauges and pipelines. The one end of the kill manifold is connected to the drilling spool and the other end is connected to the pump. The manifold and choke manifold are both designed to API 16C and can be used together. The manifold is available from 14MPa, 21MPa, 35MPa and 70MPa pressure ratings.   3. Operating Requirements (1) Working pressure of all pipelines, gate valves and check valves shall be compatible with that of the BOP stack used.     Product Show:
