Problems solved by technology

[0002] The high-pressure hose used between the oil drilling outlet and the blowout prevention mechanism, because its inner tube is easily corroded by hydrogen sulfide, resulting in leakage of the hose pipeline and accidents
Blowout fire accidents and hydrogen sulfide leakage accidents often occur in oil fields at home and abroad, resulting in equipment losses and casualties.
At present, the structure of various composite pipelines and the constituent materials of the pipe layer are various, but due to the poor corrosion resistance of hydrogen sulfide in the inner pipe layer that complies with the hose, its service life is difficult to meet the requirements, and the outer rubber layer directly Covered on the steel wire winding layer that constitutes the reinforcement layer, the steel wire winding layer with excellent thermal conductivity directly conducts the external temperature from the outer tube layer with poor heat insulation and flame retardancy to the inner tube layer, causing damage to the inner tube layer; in addition , the steel wire layer is directly wound on the inner tube layer, causing mechanical damage to the inner tube layer is very easy to occur, resulting in damage to the inner tube layer

Abstract

The invention belongs to the technical field of hose pipes and discloses a fire-proof and hydrogen-sulfide-resistance high-pressure hose and a preparation method thereof. According to the technical scheme of the composite hose, the composite hose comprises an inner hose layer, an enhanced layer and an outer hose layer, wherein the enhanced layer is made of wound or woven steel wires; a bonding layer for bonding the enhanced layer is coated on the outer side of the inner hose layer; and a fire-proof and heat insulating layer is arranged on the outer side of the enhanced layer. The high-pressure hose can effectively prevent leakage of hydrogen sulfide, has excellent fire resistance performance and can meet the needs of the fields such as petroleum, chemical industries and oceans.
