API 16C Choke and Kill Manifold Systems with Control Panel
Essential Role of Choke and Kill Manifold Systems in Surface Well Control
In high-pressure oil and gas exploration, maintaining wellbore stability during kick containment procedures requires dependable surface pressure regulation infrastructure. Integrating a heavy-duty Choke and Kill Manifold into the surface blow-out preventer (BOP) stack enables drilling crews to circulate out influx fluids under strict backpressure control. Proper fluid flow routing prevents casing pressure over-pressurization while safeguarding the formation envelope.
Shanghai PME Industrial manufactures engineered manifold spreads in full compliance with API Spec 16C standards. Designed to withstand erosive drilling muds and high-velocity gas kicks, our integrated assemblies provide accurate flow modulation, emergency fluid injection capability, and real-time pressure monitoring across land and offshore rig platforms.

Engineered Configuration of Choke and Kill Assemblies
The choke manifold sub-assembly plays a critical role in controlling wellbore pressure during fluid circulation. Standard configurations incorporate high-integrity gate valve units, adjustable choke valve assemblies for variable flow regulation, heavy-wall flanged pup connections, cross blocks, and pressure gauge transmitters for precise monitoring.
Working in conjunction with the choke line, the kill manifold in well control system installations provides a dedicated fluid injection channel to deliver high-density drilling fluid directly into the wellbore. Constructed with dependable gate valve barriers, an inline check valve to prevent backflow into high-pressure pumps, flanged pup spools, and a heavy-duty structural steel skid, the kill manifold maintains operational safety during critical well servicing routines.
