Key words:
Flexible Choke And Kill Hose
Classification:
Quick Overview:
The SL994 Flexible Choke and Kill Hose, also known as a choke hose, kill hose, or well control hose, is engineered for critical high-pressure fluid control during well control operations. Built to API Spec. 16C standards, it operates reliably from -29°C to +121°C (-20°F to +250°F) and supports working pressures up to 15,000 psi. Featuring flame-resistant, abrasion- and ozone-resistant synthetic rubber and a stainless steel protective armor, it ensures safety and durability in harsh offshore and onshore environments. Available in 2" to 4" (DN50–DN100) sizes, it is widely used on BOP stack manifolds, choke control panels, kill line loops, and subsea well intervention units, helping operators maintain safe, continuous well control and fluid transfer.
Description
SL994 Flexible Choke and Kill Hose – API 16C & ABS Certified
Application:
•Flexible connection for choke and kill manifolds and similar high-pressure systems
•Transfer of oil and gas mixtures containing H₂S and other hazardous gases
