As the national economy development and people’s living standard, thin-walled round pipe and Stainless Steel Pipe Pieces of the domestic water supply pipeline system has become the new trend of development. Thin-walled stainless steel round bar pipe
domestic 20th century until the late 90’s came the new Pipe , Because of its safety and health, high strength, good corrosion resistance, durable, long life, maintenance-free, beautiful and so on, the current strong momentum of development of stainless steel round bar pipe, have been widely used in Building Water and Drinking Water pipes.
2001 8 24 Ministry of Construction released CJ/T151 thin-walled stainless steel pipes and stainless steel compression type CJ/T152 Pipe Industry standards.
2001 National Science and Technology of China Technology Market Management Promotion Center has released application on the promotion of “high-diameter ratio of high-precision stainless steel wall, high pressure water pipes and related fittings and special technologies” to inform, thin-walled stainless steel tube to give full recognition that the popularization and application of technology and products will raising the grade of modern architecture, to improve and protect the water quality is of great significance.
2003 1 2 Ministry of Construction released the “National civil Project Design measures “in the notice, that” preference should wall stainless steel pipe steel pipe. ”
2003 7 10 from country of Quality Supervision, Inspection and Quarantine issued a GB/T19228.1, GB/T19228.2, GB/T19228.3 series of standards, promotion of compression-type stainless steel pipeline system.
2003 9 25 China Engineering Construction Standardization Association released CECS153-2003 thin-wall stainless steel water supply pipeline construction engineering.
Beijing Water Corporation  No. 194 Document: prohibit the use of galvanized pipes, to promote the use of stainless steel pipe, copper pipe was excluded.
2004 1 dated after 1 new building materials through water audits, non-acceptance does not meet the requirements through the water.
2004 7 12 Ministry of Construction approved by the Architectural Design and Research Institute of Tongji editor of the “building water supply metal pipe installation?? Thin-walled stainless steel tube” (04S407-2) for the National Building Standard Design, since August 2004 15, to implement.
Some aluminum products export tariffs will be reduced to zero import tariffs on aluminum
Learned yesterday from the Ministry of Finance, approved by the State Council, from August 1, 2007 onwards, to form the provisional tax rate will be aluminum import tariff from 5% to 0%; on non-alloy aluminum section, Export tariff levy provisional pole, provisional tax rate is 15%.
Ministry of Finance made it clear that a move to further restrict the high energy consumption, high pollution and resource exports, and promote Energy Consumption, encourage imports of raw materials. One analyst pointed out that the abolition of import duty on electrolytic aluminum line with government suppression of domestic aluminum production capacity expansion intentions.
For the policy issued on the impact of electrolytic aluminum industry, the insiders believe that this policy change has little effect on the aluminum market because of the domestic aluminum prices have been lower than the international market. Currently, LME (London Metal Exchange) aluminum price of 2800 U.S. dollars / ton, while the domestic prices in 2640 U.S. dollars / ton, even if the removal of import tariffs, importers are also unprofitable. And imports of electrolytic aluminum in China is now the total is relatively low, the domestic electrolytic aluminum production can satisfy the market demand, it will not cause the increase in market supply.
Although the aluminum industry since 2003 has been the focus of the national macro-control areas, but high demand by domestic and foreign markets, high price, high-profit-driven, the current alumina and aluminum industry and further expansion of investment and production.
