Factory Price API 16C Choke Manifold for Petroleum Oil & Gas Drilling
Choke manifold is a necessary device in the process of blowout control and implementation of oil and gas pressure control technology. In case that the BOP is off, the pressure at the bottom of well shall be kept higher than formation pressure through controlling casing pressure with choke valve on-off. Additionally, soft shut-in can be realized through relieving pressure with choke manifold in the process of well shut-in. When pressure in well rech at extreme limitation,it can be used to prevent blowout and protect wellhead.
Choke and Kill Manifold is used to control well kick and pressure. In case of well kick or blowout, Choke Manifold may control downhole pressure by valves open/close. Heavy slurry may be pumped into well by Kill Manifold to reach pressure balance. Besides, Choke Manifold can be applied to well cleanup and blow-off.
Choke manifold consists of four manual gate valves (also called diamont choke manifold, five gate valves if a bypass valve is included). It is used to control the flow rate and reduces well pressure before the flow enters the processing equipment. The maniflod also includes a positive choke box, an adjstable choke, and several pressure or sampling ports and thermowells to monitor pressure, temperature, and fluid characteristics.
3. Working Principle
When well pressure rises, the choke valve (it falls into three kinds: Manually adjustable, hydraulic and positive) on choke manifold can be turned on and off to release the fluid to control casing pressure. Gate valve can be used for direct blowout. When casing pressure is pretty high,
The pressure class of our company's chokes manifold falls into five class: 14MPa, 21MPa, 35MPa, 70MPa and 105MPa. Also, we can design according to customer demand.
