Product DescriptionIntroduction of API 7K High pressure cement hosesThe API 7K high-pressure cement hose is a specialized hose manufactured in strict accordance with the API 7K standard. It consists of an inner rubber layer resistant to cement slurry corrosion, a reinforcement layer of high-strength steel wires or fiber cords for pressure and tensile resistance, and an outer rubber layer with wear and weather resistance. It is designed for transporting high-pressure cement slurry in oil and gas well cementing operations.Structure· Inner layer: Oil-resistant, seawater-resistant, high-temperature-resistant synthetic rubber based on nitrile rubber.· Middle layer: High-strength fabric cloth is used as the inner buffer layer and outer protective layer; high-strength steel wire rope is used as the pressure-bearing skeleton material.· Outer layer: Made of high-temperature resistant, wear-resistant, oil resistant, and ozone aging resistant synthetic rubber.SpecificationsAPI 7K High Pressure Cement Hose Production Process1. Raw Material PreparationMaterial Selection:Inner layer: Oil- and corrosion-resistant nitrile or hydrogenated nitrile rubber.Reinforcement: High-strength steel wire or fiber cord, surface-treated for adhesion.Outer layer: Wear- and weather-resistant rubber (e.g., neoprene or EPDM).Material Testing:Physical, mechanical, and chemical tests to ensure quality and compliance.2. Inner Layer ExtrusionMix rubber compounds with additives and extrude into a tube via an extruder.Control temperature, pressure, and speed for uniformity and accuracy.Quality Check: Dimensions and surface quality (smooth, defect-free).3. Reinforcement Layer WindingWind steel wire or fiber cord over the inner layer at a specified angle and density.Quality Check: Reinforcement density and adhesion to the inner layer.4. Outer Layer ExtrusionExtrude outer rubber layer over the reinforcement under controlled parameters.Quality Check: Dimensions and surface integrity.5. VulcanizationCure the assembled hose in a vulcanization tank under heat and pressure to bond all layers.Quality Check: Vulcanization degree and inter-layer adhesion.6. Cutting and End ProcessingCut hose to required length.Skive ends to expose reinforcement, clean, and install fittings (e.g., via crimping).7. Final InspectionPressure Test: Hydrostatic/pneumatic tests to check for leaks or deformation.Dimensional Check: Verify length, diameter, etc.Marking: Label with specifications, pressure rating, and manufacturer details.8. Packaging and StoragePack with protective materials (e.g., plastic film) and label clearly.Store in a dry, cool, ventilated area away from sunlight and chemicals.Stack neatly to avoid deformation.Applications1. Oil & Gas CementingUsed as a flexible connector in cementing manifolds, this hose reliably transports water- or oil-based mud under high pressure. It injects cement slurry into the wellbore-casing annulus to seal formations, reinforce well integrity, and ensure subsequent extraction safety—critical for both onshore deep wells and offshore platforms.2. Drilling & Workover SupportProvides flexible connections between the riser top and top drive, or pumps and riser bottom. It delivers high-pressure mud to cool drill bits, carry cuttings, and enhance drilling efficiency. Also supports production restoration during workovers and adapts to complex geological conditions.3. Special Well OperationsSuitable for wells containing hazardous gases (e.g., H2S). Serves as a flexible line in choke & kill manifolds, transporting oil-gas mixtures and various kill fluids (water-/oil-based/foam). Ensures well control safety under high pressure, high temperature, and corrosive conditions, and helps prevent blowouts.4. Offshore Oil DevelopmentWithstands harsh marine environments (salt spray, waves). As a key component of offshore drilling mud and cementing manifolds, it transports drilling mud, cement slurry, and cleanout fluids, supporting efficient oil and gas development in varying water depths and sea conditions.Features and benefits· Wear resistance: Usually made of NR&SBR synthetic rubber, it has excellent wear resistance, oil resistance, and chemical corrosion resistance.· Wide application range: Widely used in various aspects of petroleum drilling and completion operations, including mud circulation, cementing, oil testing, completion, etc. In addition, it is widely used in fields such as natural gas extraction, water conservancy engineering, and construction engineering.· Good sealing performance: The hose connection is equipped with sealing components to prevent mud leakage from causing environmental pollution and safety accidents.· High pressure resistance: Working pressure up to 15,000Psi, test pressure 22,500Psi, burst pressure 33,750Psi.· Temperature range: -29℃—121℃.· End connection options: Hammer union or flangePackaging & ShippingPack with protective materials (e.g., plastic film) and ship in wooden cases or steel-frame crates.Why choose us?There are several compelling reasons to partner with us:1.
