　　What are the classifications and applications of large-diameter high-pressure hoses?

　　Large-diameter rubber hoses are generally classified into two types based on their applications: in everyday life, in today’s society… Large-diameter high-pressure hose Its applications are quite widespread, so what are the classifications and uses of large-diameter high-pressure hoses?

　　What are the classifications and applications of large-diameter high-pressure hoses?

　　1. Large-diameter conveying hose: The raw material is natural rubber, manufactured through processes involving various additives. It exhibits excellent resistance to oils, hydraulic fluids, lubricants, diesel fuel, and other corrosive substances. An ideal choice for construction sites, steel mills, oilfields, shipyards, and pipeline systems, it offers superior fatigue resistance and high modulus. A key advantage of large‑diameter rubber hoses is their enhanced resistance to bending, which improves their ability to withstand buckling and reduces the risk of rubber core failure; this performance is closely linked to their fatigue resistance. Consequently, the reinforcing carcass material must possess outstanding fatigue resistance and a high modulus.

　　2. It utilizes hydraulic hoses from renowned brands and high‑quality domestically produced connectors. With a wide range of products and complete specifications, we specialize in offering transition fittings, hydraulic hose assemblies, imported hose assemblies, wholesale high‑pressure hoses, wire‑braided hoses, and more. Our product line is broadly categorized into several major series: wire‑braided high‑pressure hose assemblies, wire‑wrapped ultra‑high‑pressure hose assemblies, stainless steel metal hose assemblies, nylon resin hoses, paint hoses, high‑temperature PTFE hose assemblies, imported metering pressure hoses, quick‑connect couplings, various types of oil seals, metric, imperial, British, American, and Japanese‑standard threaded hose fittings, transition fittings, and hydraulic components. We provide high‑quality supporting services to manufacturers in fields such as construction machinery, mining equipment, port handling machinery, metallurgy, petroleum, construction, chemical engineering, textiles, shipbuilding, pharmaceuticals, food processing, aerospace, and the automotive industry.

　　 Large-diameter high-pressure hose What precautions should be taken for safe use?

　　1. Rubber hoses may only be used to convey the media specified in the conveyor’s design.

　　2. Large-diameter high-pressure hoses must never exceed their rated working pressure.

　　3. The temperature of the conveyed medium in rubber hoses should not exceed the manufacturer’s specified limits: oil, –40 to 120°C; air, –30 to 50°C; water and emulsions, below 80°C.

　　4. Test tubes shall be kept clean and their interiors thoroughly rinsed to prevent foreign matter from entering the lumen, which could impede fluid delivery and damage the equipment.

　　5. Rubber hoses should be routed as far as possible from heat sources. This helps prevent the hoses from degrading due to thermal exposure during installation or when used with insulating panels.

　　6. Large-diameter high-pressure hoses shall be protected to prevent rupture caused by abrasion.

　　7. Rubber hoses should be used whenever possible. When bending is necessary, avoid sharp bends; the bending radius must not be too small and should be greater than nine times the outer diameter. At the joints where hoses are connected to fittings, there should be a straight section extending beyond the outer diameter.

　　8. Do not twist the pipes during installation. Slightly reverse the rubber hose to reduce its tension and loosen the connection. When assembling, tighten the fittings on the pipe rather than the hoses on the connectors.

　　9. When installing piping, avoid over-tightening. Allow for a certain amount of slack to keep the pipe relaxed.

　　10. During daily use, take care to protect the rubber hose and prevent it from being crushed or damaged.

　　11. When operating the control valve, handle it gently to minimize impact on the pressure line and prevent the rubber hose from bursting.

　　12. Large-diameter high-pressure hoses must be fitted with approved “U”-type clamps, sealing rings, two‑way fittings, three‑way fittings, and other specified components. The use of any alternative substitutes is strictly prohibited.

　　13. Existing cracks exhibiting leakage, rupture, bulging, rusted joints, exposed steel wires, or degraded rubber layers.

　　14. In daily use, be sure to conduct regular inspections and replace components as needed.

　　15. Newly installed or replaced hoses must be inspected and certified before use. They may be used only after passing the test. During testing, no personnel shall be allowed to approach.
