Fire-Rated Tensioner Hose, Oil Field Hose Type: NHG-SZ

The fire-rated tensioner hose is also used as an oil field hose in offshore platforms for its outstanding fire protection. The hose can be equipped with an electric heating tracing feature to make it applicable to low-temperature operation conditions, and the outer cover can be equipped with a stainless-steel armored cover, stainless-steel wire, or a polyethylene helix cover according to specific requirements.

Advantages:

Application: The rubber hose is widely used for tensioner systems in deep water, semi-submersible drilling units to deliver flame resistant hydraulic oil, as well as fix the drill pipe position.
