Product Details

Polyurethane negative pressure hoses are made under a molding technology where two surfaces are squeezed out from the inner and outer surfaces with strips woven by high-strength synthetic fibers. Their main feature is that they can withstand positive and negative pressure and be embedded underground for use; each hose is long, positive and negative pressure resistant, abrasion resistant, corrosion resistant, and has strong environmental adaptability. When the hose is partially damaged, use a fixture to stop the flow and use a connector to connect the nozzle stub for repair. As the surface of the inner wall material is smooth, only micro-shock is generated in the pipe wall transportation, the insulation material is not easily fouled, relieving the steel pipelines of the current risk of partial or even complete blockage. They are mianly used in the crude oil transmission under the ASP flooding technology in oil field exploitation.
