The growth rate of production value slowed down significantly As of the end of July, there were 35,773 enterprises above designated size in the industry, and the total output value for the month reached 713.44 billion yuan, a year-on-year increase of 24.4%, and the growth rate slowed down by 7.2% from the previous month. This is mainly due to price factors. The monthly oil and gas exploration and refining industry product prices have both fallen sharply. From January to July, the total output value of the industry was 4.81 trillion yuan, an increase of 38.2% year-on-year. Among them, the output value of new products was 263.2 billion yuan, a year-on-year increase of 49.2%. In July, the output value of the oil and natural gas exploration and refining industry was 83.49 billion yuan and 194.47 billion yuan respectively, representing an increase of 24.4% and 14% year-on-year growth. The output value of the chemical industry increased by 24.5%, a decrease of 2.4% from the previous month. In the chemical industry, the manufacturing industries of chemical mining, special chemicals, pesticides, and basic chemical raw materials grew rapidly. The year-on-year increase in output value was 40.8%, 28.1%, 27.9%, and 26.6% respectively; the output value of chemical fertilizers and rubber products industry were respectively year-on-year. The growth rate was 20.2% and 20.4%, the increase rate was 3.8% lower than that in June and 0.3% higher. From January to July, the output value of foreign-funded enterprises was 634.284 billion yuan, a year-on-year increase of 41%; the output value of Hong Kong, Macao and Taiwan companies was 300.95 billion yuan, an increase of 31.2% year-on-year; the output value of domestic-funded enterprises was 3.88 trillion yuan, a year-on-year increase of 41.4. %.
The increase in the output of major products fell. In July, although the output of major domestic petrochemical products continued to maintain rapid growth, most of the increase in output fell back compared with the previous month. The output of 78 (species) key petrochemical and related products tracked by the China Petroleum and Chemical Industry Federation showed that there were 61 (species) products that had grown and remained flat compared to the same period last year, a decrease of 5 species from the previous month, and a decrease of 17 species (species). Five kinds were added last month. In July, crude oil production maintained a rapid growth, with output reaching 17.224 million tons, an increase of 6.4% year-on-year; natural gas production of 7.19 billion cubic meters, an increase of 3.6% year-on-year; crude oil processing volume of 35.28 million tons, a year-on-year increase of 6.7%; refined oil output (gas, The total of coal and diesel, the same as below, was 21.318 million tons, an increase of 3.5% over the same period last year. Due to sluggish growth in domestic and international market demand, in July, the nation’s fertilizer production fell for the first time this year, with output of 5.502 million tons, a decrease of 440,000 tons from the previous month and a year-on-year decrease of 0.1%. The growth of pesticides has accelerated significantly. The output was 229 thousand tons, an increase of 29.4% over the previous year; ethylene production was 1.166 million tons, an increase of 33.6%; sulfuric acid production was 5.571 million tons, an increase of 24.9%; synthetic resin production was 3.648 million tons, an increase of 20.1%; tire tire production 6307.9 Ten thousand, an increase of 9.5%; production of 1.647 million tons of soda ash, a year-on-year decrease of 1.9%; methanol production of 1.158 million tons, a year-on-year decrease of 1.5%; ammonia production of 4.068 million tons, a year-on-year drop of 5%; calcium carbide production a larger decline of 13.4%.
Price increase narrowed the smooth production and sales In July, the price increase of the oil and chemical industries narrowed significantly from last month. Among them, the price increase of oil and gas exploration industry fell the most. According to the industry price index released by the National Bureau of Statistics, in July, the price index for the oil and chemical industries was 109.69 points (the price for the same period in the previous year was 100), which fell by 9.5 points month on month. Among them, the oil and gas exploration industry price index was 118.54 points, down 26.6 points from the previous month; the petroleum processing industry price index was 112.41 points, down 10.2 points month-on-month; the chemical industry price index was 107.25 points, down 0.78 points month-on-month, with the smallest decrease. In July, the sales rate of products in the petroleum and chemical industries was 98.2%, up 0.16% year-on-year and 0.7% month-on-month. The connection between production and sales was basically smooth.
Slower export growth In July, the export delivery value of the petroleum and chemical industry was 38.21 billion yuan, an increase of 25% year-on-year, and the growth rate dropped by 3.8% from the previous quarter.
Investment maintains steady growth This year, the investment in fixed assets of the petroleum and chemical industries has maintained a steady growth. From January to July, the accumulated investment of the industry was 597.694 billion yuan, a year-on-year increase of 16%, and the growth rate was 2.5% higher than the same period of last year. Among them, the investment in the oil and natural gas exploration industry increased by 10.7%, the refining industry increased by 5.4%, the chemical industry increased by 19.9%, and investment in the special equipment manufacturing industry continued to decline, falling by 20.5%. In the chemical industry investment, the chemical mining industry increased by 60%, the synthetic material manufacturing industry increased by 54.7%, the inorganic salt manufacturing industry increased by 51.4%, the phosphate fertilizer industry increased by 47.2%, the dye manufacturing industry increased by 44.3%, and the rubber product industry increased. It also reached 35.3%, both greatly exceeding the average increase in industry investment.
At present, although the economic operation of the petroleum and chemical industries faces a very complex economic environment at home and abroad, the trend toward a stable and stable industrial economy has not changed. According to the analysis of the current economic situation, it is expected that the total output value of the industry in the third quarter will increase by about 24%, and it will increase by about 26% in August. Among them, the output value of the chemical industry in August increased by approximately 25.5%. The growth rate of the consumption of major products will obviously slow down. It is estimated that the apparent domestic consumption of crude oil in the third quarter will be approximately 108 million tons, an increase of 5.8%; the apparent consumption of refined oil will be approximately 60 million tons, an increase of approximately 1.2%; the apparent consumption of ethylene will be approximately 3.2 million tons, an increase of approximately 4.5%. %; The apparent consumption of synthetic resin is about 17.2 million tons, an increase of about 4.4%; the apparent consumption of chemical fertilizer is about 16.6 million tons, an increase of about 4.5%.
In the third quarter, the petrochemical market will focus on smooth operation, and short-term and local fluctuations may occur. Judging from the current economic environment and domestic and foreign market demand, in the third quarter, the domestic oil and chemical industry price level will gradually narrow, and the petrochemical market will generally show a stable operation trend, but the trend of each sector will be different. In the third quarter, the fertilizer market will be slightly better than the previous quarter, but the downturn will not be fundamentally reversed; the inorganic chemical raw material market will be mainly stable, and may show a steady upward trend; the organic chemical raw materials and synthetic materials market may experience downward shocks. The trend will increase its market competition.
The boiler water wall is the main radiation heat surface, arranged inside the boiler chamber and proceeds the heat exchange directly with the high temperature flame. The convection tubes are the convection heat surface of the boiler, arranged between the boiler chamber outlet and the end heat surface and proceed the heat exchange directly with the high temperature fume. The water wall and convection tubes are the main heat surface of the boiler, the tubes diameter for both generally usedΦ 51-60mm boiler steel tubes, also as the request.
The first type is the bare pipe water wall. This is the simplest structure of the water wall. The advantage is that ordinary seamless steel pipes can be used, and it is more convenient to replace the water wall pipe. The disadvantage is that the temperature of the furnace wall is still high, and heavy refractory bricks are required. The steel frame of the corresponding boiler should be strengthened. , The air leakage of the furnace wall is relatively large. Old-fashioned high-pressure boilers and medium and small boilers are used more frequently.
The second tupe is the membrane water wall. The membrane water wall is welded by seamless steel tubes with fins. The Water Wall Tubes are connected by fins to make the water wall into a whole. This kind of water wall is called a membrane water wall. Its function is to strengthen the heat transfer of the water wall and greatly reduce the temperature of the furnace wall. The furnace wall does not need refractory bricks, but only requires thermal insulation materials. Compared with the conventional heavy furnace wall, the weight can be reduced by 60% ~ 70%, the furnace wall heat storage is reduced by 80%, the start and stop time is shortened, and the fuel consumption is reduced. The load of the furnace steel frame is greatly reduced, saving refractory materials and steel.
The third type is the pierced pipe water wall. The barbed pipe water wall pipe is made by welding many grab nails with a length of 20 to 26 mm and a diameter of 6 to 12 mm on the water wall pipe. It is mainly used to lay the gas belt. Generally, for boilers that burn fuel with low calorific value and low volatile content, in order to stabilize the fire, pierced pipe water walls are often used for laying the fire protection belt.
