A kind of petrochemical industry is with high-temperature resisting alloy furnace tubes by adopting and pipe row's production line
Technical field:
The utility model relates to the production line of a kind of petrochemical industry with high-temperature resisting alloy furnace tubes by adopting and pipe row; It is used for each processing apparatus of production process such as casting, machining, welding, packing; And necessary checkout equipment and monitoring point rational deployment between the operation, and all connect into production line with track, boiler tube and pipe thereof are come on the production line flow in a rational and orderly way; Through production process and check problem relevant in the production line, become qualified boiler tube and pipe row product thereof.
Background technology:
Petrochemical industry is with boiler tube and pipe row, and it is mainly used in petrochemical industry ethane cracking furnace and hydrogen manufacturing conversion furnace.
Ethane cracking furnace is a heart of making the ethylene product unstripped gas with oil gas.Ethylene product is again the industrial chemicals product that is related to people's clothing, food, lodging and transportion--basic necessities of life.The development level of ethylene product is the outstanding feature of a national petrochemical industry development level.
Hydrogen manufacturing conversion furnace is to make hydrogen with oil gas, is used for synthetic ammonia and makes chemical fertilizer, developing agricultural production; Be used for synthesizing methanol, can be used as the basic material of chemical products such as dimethyl ether, acetic acid partly as the substitute of gasoline; Be used for the raw material of metallurgy industry as the iron reduction; Be used in particular for the oil refining industry hydrogenation, can improve the quality of gasoline, reach pollution control regulation, be used for hydrocracking and refine more better oil products from the heavy wax oil to the increasingly high requirement of oil product.
If ours is that the clean energy resource of power is succeeded in developing with hydrogen, the present gas station of Na Jia hydrogen station picture as many must have the hydrogen manufacturing conversion furnace of corresponding manufacturing hydrogen just can satisfy the demand.
