As a flexible pipe made of polyurethane reinforced with embedded hard plastic spiral ribs, Plastic Reinforced Pu Hose accommodates a wide range of conveyed media thanks to its stable material properties and special structure. It handles gaseous, liquid and solid substances and serves as a highly universal delivery pipe for both industrial and civil fields, though certain media are prohibited. For gaseous medium transportation, it acts as core piping for ventilation, dust removal and pneumatic conveying. It can steadily deliver normal‑temperature compressed air, ambient air, dry nitrogen and other inert industrial gases. It suits workshop ventilation, mechanical equipment exhaust, negative‑pressure air intake for dust collection systems and gas transmission for pneumatic devices. Sound sealing performance prevents air leakage, and it can run stably under low‑and‑medium‑pressure gas delivery conditions.
In liquid conveyance, this hose adapts to most normal‑temperature neutral fluids including clean water, general industrial water, circulating cooling water and slightly oily‑water mixtures as well as low‑concentration alcohol aqueous solutions. It resists low‑concentration weak acid, weak alkali and salt‑containing aqueous solutions for light‑industry, diluted food auxiliary liquid and ordinary dilute chemical liquid transportation. Nevertheless, highly corrosive substances such as concentrated hydrochloric acid, concentrated sulfuric acid, strong alkaline solutions, organic solvents and gasoline must be avoided, as these substances will erode polyurethane and cause tube aging and damage. Besides, it is only intended for normal‑temperature liquid delivery. Boiling water and high‑temperature oil will accelerate tube deformation and aging.
For solid material delivery, it shows prominent advantages. Benefiting from wear‑resistance and tear‑resistance, it can transport various small‑and‑medium‑sized solid particles efficiently, including grains, feed pellets, plastic particles, rubber granules, wood chips, wood powder, fly ash, fine sand and cement powder. It is extensively used in woodworking dust extraction, building‑material powder conveying, agricultural grain suction, plastic‑industry material transfer and sanitation vacuum cleaning. Built‑in plastic ribs prevent tube flattening and collapse under negative pressure and guarantee smooth material flow without blockage.
There are clear conveyance restrictions for this hose. Large‑sized materials with sharp edges such as bulky crushed stones and angular metal scraps will scratch tube walls after long‑term delivery. High‑temperature molten materials, strongly corrosive chemicals and high‑viscosity curing substances are forbidden since they will destroy tube structure and shorten service life sharply. Generally speaking, Plastic Reinforced Pu Hose is designed for normal‑temperature, non‑strong‑corrosion gas, liquid and solid transportation under regular conditions. It is widely used in light industry, building‑material, agriculture, dust‑removal and machinery sectors and replaces traditional rubber and PVC hoses with better overall adaptability.
