Pneumatic tubes using tips: Polyurethane pneumatic hoses for compressed air, general industrial water, non-corrosive oil. To maintain long-lasting life, will face used on the rated working pressure and ambient temperature. As the temperature rises insulating sleeve, working pressure should be reduced, if it exceeds the limit, the hose may be broken. Fluid temperature is too high or corrosive fluid chemical costs, may result in hose rupture, ambient temperature is too high or workspace chemical gases may cause the hose cracking, storage in damp places or deposit side of too long, will make the hose hydrolysis or aging, may lead to breakage pvc pipe | Features and use from the beginning of the 1940s, polyethylene pipe, once launched, it will be because of their excellent performance and economical rapid promotion insulation sleeve pipe poison, after 60 years of development, has become the use of polyethylene pipe performance, perfect design theory, the product is complete, the production and life indispensable to a plastic pipe.
