Product DescriptionIntroduction of API 7K High pressure Rotary Drilling HoseDesigned for oil drilling and exploration, this API 7K rotary drilling hoses enables flexible high-pressure mud conveyance in critical rig configurations. It serves as the essential flexible link between the upper end of the standpipe and top drive/swivel, as well as between the mud pump and lower standpipe end, ensuring reliable high-pressure mud pumping during drilling operations.API 7K Rotary drilling hoses engineered to handle high-temperature mud (operating temperature: -20°C to +121°C), the hose features reinforced construction—typically with multi-layer high-tensile steel wire braiding and abrasion-resistant synthetic rubber linings—to withstand extreme pressures and harsh drilling fluids. Its flexible design accommodates dynamic movements in rig setups, reducing stress on connections and minimizing leakage risks.StructureInner layer: NR/SBR/NBR/HNBR Reinforced layer: multi-layer high-tensile steel wire or steel wire rope Outer layer: abrasion-resistant and weather-resistant synthetic rubberSpecificationsAPI 7K High Pressure Rotary Drilling 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. Critical Drilling ConnectionsServes as a flexible link between the riser and top drive, as well as pumps and the riser base. It enables high-pressure mud transfer in oil drilling, buffering vibrations and compensating misalignment. Ensures stable mud circulation for bit cooling and cuttings removal. Widely applied in offshore fields (e.g., Indonesia) and onshore shale gas projects.2. Directional & Complex DrillingIdeal for directional and extended-reach wells. Functions as a motion compensator hose on offshore platforms to absorb wave motion and stabilize drilling. Supports precise mud control in thin oil zones and sidetracking, enhancing wellbore accuracy and recovery while reducing risks.3. Workover OperationsConnects well intervention equipment to casings for delivering mud and flushing fluids under high pressure. Facilitates production restoration and adapts to various well repair needs such as casing remediation and reservoir re-drilling.4. Special EnvironmentsResists saltwater corrosion and high-temperature/acidic conditions. Used in long-length applications (>13.5m) for offshore barge-to-platform mud transfer and in hazardous (e.g., H2S) gas wells. Suitable for diverse international operations including Indonesia and the Middle East.Features and benefitsConveying mediaum: water-based mud,oil-based mud,etc.Working temperature: -20° C to +121° C (Customized)Max. available length: 60m(200ft)Connector: hammer union/ flange(crimping)Standards: API Spec.7KPackaging & 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.
