Large‑diameter high‑pressure hoses shall not be used under torsional stress; they must be handled with care, and must not be dragged across sharp or rough surfaces, nor bent or crushed. Keep them clean and flush the interior thoroughly—especially for acid‑resistant hoses, spray lines, and mortar‑delivery pipes. Prevent foreign objects from entering the hose lumen, as such obstructions can impede fluid flow and damage the equipment. Hoses that have exceeded their service life or storage period may only be reused after passing a prescribed test and certification.

　　 Large-diameter high-pressure hose Bending or kinking near pipe fittings should be avoided as much as possible, as this can impede hydraulic transmission and material conveyance or damage high-pressure hose components. Large‑diameter high-pressure hoses must not be used while twisted; they should be handled gently and never dragged across sharp or rough surfaces, nor subjected to bending or crushing. Keep them clean and flush the interior thoroughly—especially acid lines, spray lines, and mortar lines—to prevent foreign matter from entering the lumen and obstructing fluid flow, which could damage the equipment. Hoses that have exceeded their service life or storage period may only be reused after passing a thorough inspection and testing.

　　Large‑diameter high‑pressure rubber hoses are tubular rubber products used for conveying gases, liquids, slurries, or granular materials. They consist of inner and outer rubber layers as well as a reinforcing carcass layer. The carcass may be made from cotton fibers, various synthetic fibers, carbon fiber, asbestos, steel wire, or other materials. The inner and outer rubber layers typically employ natural rubber, styrene–butadiene rubber, or polybutadiene rubber; chloroprene–nitrile rubber is used for acid‑ and alkali‑resistant applications; and ethylene–propylene rubber, fluoroelastomer, or silicone rubber are selected for high‑temperature‑resistant hoses. These hoses are primarily employed in hydraulic supports for mine shafts and oilfield extraction, and are well suited for engineering construction, lifting and transportation, metallurgical forging and pressing, mining equipment, shipbuilding, injection molding machinery, agricultural machinery, and a wide range of machine tools.

　　Although Large-diameter high-pressure hose It has a multi-layered structure and is reinforced with steel wire, yet it remains quite fragile. When using and handling high-pressure hoses, we must exercise extreme care to avoid damage caused by inadvertent negligence, which could disrupt our operations. So, what precautions should we take when working with large‑diameter high-pressure hoses?

　　1. When handling and loading/unloading high-pressure hoses, do not drag them arbitrarily. Large-diameter high-pressure hoses must be loaded and unloaded using lifting equipment or specialized tools to prevent accidental damage that could impair their normal operation.

　　2. Arrange neatly and ship in rolls (or lengths) to prevent severe bending of the hose; do not stack heavy objects on the hose.

　　3. For hoses requiring straight-line transportation, when the length exceeds the compartment of the transport vehicle, the excess portion shall be supported by brackets to prevent the product from being dragged across the ground and damaged.

　　4. Large-diameter high-pressure hose During loading and unloading, handling should be gentle.

　　5. If the product must be temporarily stored outdoors (or at a workshop or dock), the storage area shall be level, with hoses neatly and evenly arranged. The bottom and top covers must be securely closed to prevent heavy objects from being stacked on them; furthermore, the hoses must not come into contact with heat sources.

　　6. Hoses must never be stored together with acids, alkalis, oils, organic solvents, or flammable and explosive materials; large‑diameter high‑pressure hoses should not come into direct contact with objects having sharp edges. The quality of our high‑pressure adhesives is reliably assured through a robust system, meticulous management, cutting‑edge technology, and state‑of‑the‑art equipment, giving you peace of mind during selection and greater confidence in use.
