API 16C Choke and Kill Hose Manufacturer
AlienFrac manufactures API 16C choke and kill hose assemblies for drilling rigs, BOP systems, choke manifolds and high-pressure drilling mud service. As a direct oilfield hose manufacturer, Alienfrac supports custom hose size, working pressure, length, end connection, armoring and inspection documents for demanding well-control projects.
Why Work With a API 16C Choke and Kill Hose Manufacturer?
Buying directly from a manufacturer gives you more control over technical selection and delivery. AlienFrac can review pressure rating, inner diameter, bending requirements, end fittings and protective cover options before production. This reduces mismatch risk and helps you receive a hose assembly that fits the well-control system instead of a generic catalog item.
• Engineering review for hose ID, pressure, length and connection.
• Manufacturing control over rubber compound, reinforcement and assembly process.
• Inspection support including hydrostatic testing, dimensional checks and visual inspection.
• Custom options for armored/unarmored and crimped/built-in hose constructions.
• Export support for drilling contractors, distributors and OEM rig packages.
What Is an API 16C Choke and Kill Hose?
An API 16C choke and kill hose is a flexible high-pressure line used in choke and kill systems for oil and gas drilling. It transfers drilling mud and well-control fluids between equipment such as the BOP, choke manifold, kill manifold, mud pump and standpipe system. Compared with rigid piping, the flexible hose helps absorb movement and vibration while maintaining a pressure-rated flow path.

Applications in Drilling and Well Control
Use this hose where a flexible, pressure-rated connection is needed in the well-control circuit. Common applications include:
Choke Manifold Lines
API 16C choke and kill hoses connect the BOP stack to the choke manifold for controlled diversion of high-pressure well fluids during drilling, kick control, and pressure testing. They provide flexible routing, vibration resistance, and reliable flow performance under demanding well-control conditions.
Kill manifold lines
For kill manifold service, API 16C choke and kill hoses deliver weighted drilling mud or kill fluid into the wellbore to regain pressure control during kicks or shut-in operations. Their high-pressure construction supports safe pumping, flexible installation, and dependable performance around the rig floor.
Bop Side Outlet Connections
API 16C choke and kill hoses are used on BOP side outlet connections to create flexible high-pressure links between the blowout preventer and well-control manifolds. They help absorb movement and vibration while maintaining secure flow paths for choke, kill, and emergency circulation operations.
High-Pressure Drilling Mud Circulation
In high-pressure drilling mud circulation, API 16C choke and kill hoses transfer mud and well-control fluids where rigid piping is difficult to install. They support continuous circulation, pressure management, and temporary flowline layouts for drilling, testing, and intervention operations.

FAQ of API 16c Choke and Kill Hose
What is an API 16C choke and kill hose?
An API 16C choke and kill hose is a flexible high-pressure hose assembly used in choke and kill systems to transfer drilling mud and well-control fluids between equipment such as the BOP, choke manifold, kill manifold and mud pumps.
Why buy from a choke and kill hose manufacturer?
A direct manufacturer can review pressure rating, hose size, length, end connection, application medium and inspection requirements before production, which helps reduce selection errors and improves project fit.
What information is needed for an API 16C hose quote?
Send the required inner diameter, working pressure, total length, connection type, media, temperature range, bend radius or installation layout, sour-service requirement, quantity and delivery location.
Can choke and kill hoses be used for sour service?
Sour-service use depends on liner material, compound design and project certification. Confirm H2S resistance and documentation requirements with the manufacturer before ordering.
What is the difference between API 16C and API 7K hose?
API 16C is associated with choke and kill equipment and flexible choke/kill lines, while API 7K is commonly associated with rotary drilling and cementing hose applications. The correct hose depends on the equipment and service conditions.
