Product Description Welded steel gas cylinders from our company are made of excellent steel plates and designed , manufactured and inspected according with GB5100, GB17673. Also they are conformity with some international standard such as ISO,DOT,BS,JIS,DIN,TUV and so on. Our cylinder can be refilled with various kinds of low pressure liquid gas such as liquid Cl2, anhydrous ammonia, sulfur dioxide, freon, ethylene etc. they are widely applied in many industries department such as chemical industries, medical, pesticide, metallurgy, paper manufacturing, rubber, plastic, textile, printing and dyeing, food, water purification, light industry, electricity, fire-fighting and so on. Ammonia is a colorless gas. It may be compressed and cooled to a colorless liquid. Ammonia is the compound formed by the chemical combination of the gaseous elements nitrogen and hydrogen. Ammonia is a highly reactive chemical, forming ammonium salts in reactions with inorganic and organic acids. Industrial ammonia is used for a wide variety of applications in varying quantities. Product Name Ammonia Chemical Formula NH3 Hazard Class 2.3 Molecular Weight 17.031 Boiling Point (C) -33.43 Boiling Point (F) -241.17 UN 1005 Density(kg/m³) 0.728 Density(lb/ft³) 0.044 Process: Industrial ammonia is purified by a filter into the electronic grade ultra-high purity ammonia. Annual output of ultra-high purity ammonia gas is 10,000 tons. Application: Ammonia(NH3)is used in 1. metal treating operations as nitriding, carbo-nitriding, bright annealing, furnace brazing, sintering, sodium hydride descaling, atomic hydrogen welding, and other applications where protective atmospheres are required 2. hydrogenation of fats and oils as a convenient source of hydrogen 3.manufacturing of alkalis, ammonium salts, dyes, pharmaceuticals, cuprammonium rayon, and nylon 4. rubber industry for stabilization of raw latex to prevent coagulation during transportation and torage 5. as a catalyst in the phenol-formaldehyde condensation and also in the urea-formaldehyde condensation to make synthetic resin 6.produce proteins and can be used to improve the protein content of low quality hay 7.semiconductor industry 8.production of blue and white LEDs (Light Emitting Diods) 9.In the field of novel optoelectronic materials, it is an important base material for GAN preparation by MOCVD technology.High purity ammonia or the preparation of nitrogen trifluoride, silicon nitride, the basic material, is the production of super high nitrogen raw gas.In addition, liquid ammonia is widely used in the semiconductor industry, the metallurgical industry, as well as other industries and scientific research that need to protect the atmosphere.
