Oilfiled Drilling Frac Hose for Acidizing and Hydraulic Fracturing¹

Product DescriptionAPI 7K Frac Hose Acid fracturing rubber hosesAcid fracturing rubber hoses are crucial components in the oil and gas industry, specifically designed for the acid fracturing process. This technique involves injecting acid into underground rock formations at high pressure to create fractures, which enhances the permeability of the reservoir and boosts the extraction of oil and gas. are widely used in mining and production operations, mainly responsible for the task of transporting high-viscosity acid fracturing fluids to underground oil layers, acid fracturing, sand fracturing, hydraulic fracturing pipelines in well completion operations. It transports water-based, oil-based, foam, acid-based and other fracturing fluids in high pressure, known as a sharp tool for activating formation venous blood.StructureInner layer: Made of acid resistant synthetic rubber or polymer composite materials, used for direct contact and transmission of fracturing fluid, effectively resisting the erosion of acidic liquids.Middle layer: High strength steel wire weaving or winding layer is used to provide necessary pressure bearing capacity and anti explosion protection, ensuring the stability of the hose under high pressure.Outer layer: Made of synthetic rubber with excellent wear resistance and anti-aging performance to ensure that the long-term use of the hose in complex environments will not be affected.Protective layer: Spiral sheathSpecificationsProduction ProcessProduction Process of High-Pressure Fracturing Hose1. Inner Tube Extrusion: A seamless, continuous tube made from special oil-resistant synthetic rubber is formed to create the fluid passage.2. High-Strength Reinforcement: Multiple layers of high-tensile steel wires are braided over the inner tube at precise angles. This robust construction provides the extreme pressure resistance.3. Cover Application: A tough, protective outer layer of abrasion and weather-resistant rubber is applied to shield the hose from external damage.4. Vulcanization: The hose is cured under heat and pressure. This process bonds all layers together permanently, giving the hose its final strength and durability.5. End Fitting Assembly: Specialized steel end fittings are precisely attached to the hose ends under high pressure, ensuring a secure, leak-proof connection.6. Rigorous Testing: Every hose undergoes strict quality control, including high-pressure hydrostatic testing, to guarantee performance and safety far exceeds its rated working pressure. ApplicationsIt is mainly used in the exploitation and production operations of shale oil and shale gas.Features and benefitsCost Saving: Fracturing hoses significantly cut down on steel pipes, components, and seals, minimizing connection points. Their innovative connections enable swift hook-ups to pump trucks and wellhead gear, thereby speeding up installation, minimizing downtime, and boosting operational efficiency.Safety: The hose design includes wear indicators and a three-color inner rubber system — white for normal use, black for extended use, and red indicating replacement needed. This allows for easy inspection and lifespan prediction.Long Service Life: Made of corrosion- and wear-resistant rubber, the hose's inner layer withstands harsh chemicals and fluids. Its outer layer, with a spiral sheath, adds wear resistance, anti-static protection, and UV shielding, ensuring durability in tough environments.High Pressure Resistance: The hose can handle up to 15,000 Psi working pressure, with a test pressure of 22,500 Psi and a burst pressure of 33,750 Psi.Flexibility and Simplicity: Unlike heavy, cumbersome traditional flow irons, frac hoses offer agility in frac operations, making them lighter and easier to handle.Operating Temperature Range: From -29°C to 100°C.Connection Options: Choose from hammer unions or flanges for versatile end connections.Why choose us?There are several compelling reasons to partner with us:1.
