metal jointing
1.Eaststar group chemical packing township of Ping Town ceramics industry accumulation area located at the chemical padding, the history is glorious, the technical force is abundant, the process unit is advanced, and with the domestic many scientific research, the Designing department and the universities, colleges and institutes establishment long-term cooperation relations, presently has the technical ceramics, the honeycomb ceramics, the metal jointing, the plastic products, the molecular sieve, the activated alumina, the catalyst and so on many plants, the main production operation petroleum, the chemical industry, the metallurgy, the drugs manufacture, the coal gas, the electric power, the papermaking, food, the light industry and the chemistry industrial used each kind of padding, including the ceramics, the metal, the plastic archery target tower padding, the molecular sieve, the activated alumina, the biochemistry filter the material, environmental protection specialized packing products and so on honeycomb ceramics.
3.According to these, the paper put forward some countermeasures: select low carbon steel or low metal alloy steel with lower intensity, like 20R steel; ② while welding, adopt strict craft measures with lower welding heat to input; ③ after jointing, proceed the whole hot dissolving on time; ④ control each welding joint with hardness HB≤185; ⑤ add 0. 25% water into the liquid ammonia as decay eclipse; ⑥ enhance checking in operation, repairing equipment in time through regular interior and exterior checking.
