? Material:? Natural rubber Uses: transport ammonia, weak acid medium manufacturers (Origin):?? Hebei Hengshui working pressure: 1-10MPa corresponding burst pressure:?? 4-40MPa nominal diameter:? DN10-DN32mm wall thickness: 3-7mm Features: transporting ammonia hose is made of high quality EPDM inner tube, steel wire braid or cord braid, weather-resistant outer layer consisting of aging. Delivery hose assembly ends of ammonia can be stainless steel one-piece flange; H can also be used type, D-type, A-type, C-type high-pressure hose fitting. Product Diameter: DN06-DN300 product temperature: -40 ℃ -120 ℃ Product Working pressure: 1-10MPa transmission medium characteristics: ammonia, also known as ammonia water, an aqueous solution of ammonia, colorless, transparent and irritating odor. Volatile, with part of the base of the continuity, the ammonia into the water in the system, and react with acid to produce heat, combustion explosion hazard. Industrial ammonia is ammonia containing 25% to 28% aqueous solution, only a small portion of the ammonia molecule reacts with water to form ammonia, ammonium ions and hydroxide ions, ie, ammonium hydroxide, ammonia is present only in the weak base. Freezing point of ammonia and ammonia concentration, commonly used (wt) 20% concentration of the freezing point of about -35 ℃. Ammonia have some corrosion, corrosive ammonia carbonation more serious. Corrosion of copper is relatively strong, steel is relatively poor, little cement corrosion. Wood also has some corrosion. Toxic ammonia, eye, nose, skin irritation and corrosive, can make a person choking, Air maximum allowable concentration 30mg / m3. Product Note: When using the transport of ammonia hoses must not be less than the minimum bend radius. Ammonia corrosion of copper large, so delivery can not use copper ammonia hose fittings, carbon steel fittings using hose, use the time to check the fitting end for corrosion, the timely replacement of joints to prevent leaks.
