According to statistics, from March to now, domestic alumina production has started to resume production, and the total production volume has been 5 million to 6 million tons.
“At present, the total domestic alumina production capacity is about 21.5 million tons.†Aluminium industry analysts said that due to the stabilization of electrolytic aluminum prices and the resumption of production by electrolytic aluminum companies, domestic alumina producers are also eager to resume production, with the exception of aluminum. Many major alumina companies, including Weiqiao Aluminum, Shandong Lubei, Henan Cayman and Dongfang Hope, have conducted trial production of alumina production lines that had been in stagnation in the past two months.
At the same time, domestic alumina imports have released days. The latest release of the Customs Express data shows that the import volume of alumina in April was 650,000 tons, which was the highest monthly import volume since 2008, second only to the single monthly import volume of 660,000 tons in January 2008. The import volume of alumina in April increased by 140% from the previous month, and the cumulative imports from January to April was 1.67 million tons, a year-on-year decrease of 2.91%.
However, as a direct raw material for electrolytic aluminum, the release of domestic alumina production capacity and the surge in alumina imports have not been supported by the supporting scale of electrolytic aluminum production. By the aluminum price from last year's low of 10,040 yuan / ton price rose to 14,900 yuan on April 10 this year / ton stimulation, electrolytic aluminum enterprises started in February began to gradually start the electrolytic cell, ready to resume production. However, the high price of aluminum did not last too long, since late April, domestic aluminum prices have been 徘徊12000-13,000 yuan / ton, which greatly undermined the electrolytic aluminum business complex impulse.
In March, there were plans to resume the production of electrolytic aluminum with a total capacity of more than 1.9 million tons, and until now, the actual starting capacity was less than half of the planned amount. If one ton of electrolytic aluminum is required to produce 1.9 tons of alumina, the capacity of re-produced alumina is higher than that of electrolytic aluminum by 3.2 million tons.
Faced with a large number of complex production, domestic alumina prices have also been reflected. It is reported that on the day of aluminum production restart in Shandong, the surrounding small-scale small alumina producers immediately lowered the factory price. At present, the domestic alumina price is close to 2,000 yuan per ton, while the current alumina alumina alumina quote is 2,300 yuan per ton.
According to understanding from Lianyungang, the amount of imports in April was ended, and the import volume in May is still not a small figure. At present, only Lianyungang has an alumina inventory of about 900,000 tons, and the total stock of ports in the country is about 1.5 million tons. Shan Guibin believes that the import of alumina in May may be lower than in April, but the import volume of more than 400,000 tons per month is almost certain.
“According to the current situation, alumina prices will continue to decline.†Aluminium enterprise traders have determined that the future domestic alumina prices are likely to be suppressed to below 2,000 yuan/ton, and it is expected that aluminum alumina prices will also be offered in June. Follow the line. The decline in domestic alumina prices will become an influx of imported alumina, so the current release of imported air is actually not terrible

Winding Structural Wall Pipe B-tube
The Kra pipe is a thermal winding pipe with a high-density polyethylene structure wall. HDPE winding structure wall pipe is a new type of special-shaped structure wall pipe. It is made through a high-density polyethylene thermal winding molding process. The products are mainly made of high-density polyethylene resin (HDPE) as raw material. The product uses PP or Pe bellows as auxiliary supporting tubes. It is high-density polyethylene large-diameter winding reinforced tubes produced by the thermal winding molding process. It is known as Kra pipe in China because this kind of pipe was originally imported from the German kra company. The official name of the product in China is high-density polyethylene structural wall thermal winding pipe. The national standard is GB/T 19472. 2-2017 B-type structural wall pipe.
The application of HDPE kra pipe
1. Municipal water supply and drainage: The internal pressure of high-density polyethylene (HDPE) winding reinforced pipe can reach 12kg/cm2, which is the ideal pipe to replace the original drainage cast iron pipe and cement pipe in the city. The pipe can be used for municipal underground drainage, sewage, rainwater collection, water transmission, ventilation, etc to discharge liquid and gaseous substances into rivers or the sea. Thermal structure wall winding pipe has the advantages of lightweight, safe, reliable connection,corrosion resistance, and high ring stiffness, therefore the use of thermal structure winding pipe has great advantages.
2. Large-scale water conservancy projects: long-distance water transmission, farmland irrigation, reservoir drainage, water source pipe, irrigation pipe and hydropower station water transmission, drainage use;
3. Environmental protection engineering: deep sea sewage, sewage treatment, waste
dump sewage, detoxification pipeline. Due to the thermal structure wall winding pipe of various pipe wall structures and pipe, inspection well, pipe fitting, and its reliable connection performance, the pipe can be used for advanced shallow drainage systems.
4. Petroleum industry: oil, gas pipeline.
5. Coal industry: coal transport, ventilation systems.
6. Chemical engineering: chemical containers, especially corrosive fluid delivery
pipelines.
7. Electric power engineering: circulating water pipeline.
8. Road engineering: crossing roads and railways have a large traffic load of water
culverts and crosswalks; Used as railway and highway road seepage, drainage pipe; The method of "liner in pipe" is becoming more and more important for repairing damaged pipes.
9. The laying of pipes in a corrosive environment.
10. Agricultural engineering: farmland, orchard, tea garden and forest belt irrigation, and so on;
11. Large airport port, wharf engineering: large airport port, wharf engineering drainage, sewage pipe, etc.
12. Construction engineering: building stormwater pipes, underground drainage pipes, sewage pipes, ventilation pipes, etc.
Communication tube: railway, highway communications, communication cables, optical cable protection pipe.
14. Water storage system: used to intercept the slow water storage system.
15. Special application: thermal winding wall winding pipe can also be used for special
purposes such as ventilation, passage, desert, swamp, lake area with fluid transport, etc.
