BOP Well-Control Hose is composed of the inner rubber, reinforced layer, fire-retardant insulation layer and protective layer.
BOP Well-Control Hose Structure apply to drilling control devices hydraulic control pipeline.
Temperature: -20 ℃ ~ +121 ℃, can be 1093 ℃ (2000 ° F) flame temperature, under the conditions of sustained pressure for more than 5 minutes.
Executive Standard: API Spec 16D
The product is technologically advanced and adaptable. In 2002, it was listed as a Torch Program by the State. It can last for more than 5 minutes under the working pressure of 1093 ℃ (2000 ℉) flame temperature.
The pipe body has the characteristics of high pressure resistance, heat insulation, flame retardant and fire resistance, etc., and the inner wall is highly wear-resistant. The pipe body has the advantages of no resistance and long service life, and is adapt to the soft connection of the blowout preventer pipeline inside and outside the wellsite and the soft connection of the choke and kill hose.
