　　What are the uses and characteristics of choke and kill manifold?
　　1、 Purpose: choke and kill manifold is mainly used for soft connection of internal and external nozzles, flexible connection between mud gas separator and choke manifold. It not only has high pressure resistance, heat insulation, flame retardance, fire resistance and other properties, but also has ultra-high wear resistance of inner wall than steel pipe.
　　2、 Features: the choke and kill manifold joint adopts international integral vulcanization type, integral flange type and integral union type. The diameter of the pipe body has no resistance and the service life of the pipe body is long. The choke and kill manifold is suitable for the soft connection of the internal and external blowoff pipelines and the choke and kill pipelines.

　　1. Flexible choke and kill manifold (pipeline) is suitable for the relative movement of drilling platform, semi submersible drilling ship or drilling ship, and the connection of parts with the change of drilling rig installation size in the future, conveying oil, gas, mud and other high-pressure media (mainly including blowout pipeline, blowout pipeline, choke and kill pipeline).
　　2. Executive Standards of choke and kill manifold: API Spec 16C and SY / T 5323-2004.
　　3. The choke and kill manifold has the characteristics of high pressure resistance, heat insulation, flame retardant, fire resistance, and high wear resistance on the inner wall.
