Choke manifold is used mainly for controlling casing pressure, keeping wellbore balance, avoiding overflow and preventing wells from blowing out. Kill manifold is a key equipment for pumping heavy drilling fluids into the well for bottom hole pressure balance, for releasing bottom hole pressure, and for injecting water to wash well or for injecting extinguishing agents. High pressure ground control units are indispensable to formation and oil testing. All parts are heat treated and have passed the hydrostatic pressure test under maximum pressure rating. These equipments are manufactured to conform to API Spec 16 of NACE Standard MR0175 and can be designed according to user’s request.
