subject: Thin Round Steel Pipe Application Development Trends In China [print this page] As the national economy development and people's living standard, thin round steel pipes and stainless steel pipe fittings water supply pipeline system has become the new trend of development.
Internal wall stainless steel round bar pipe in the 20th century until the late '90s came a new type of pipe, because of its safety and health, high strength, good corrosion resistance, durable, long life, maintenance-free, beautiful and so on, the current round stainless steel strong momentum of development of steel pipe, have been widely used in building water supply and the direct water pipe.
August 24, 2001 the Ministry of Construction released CJ/T151 thin-walled stainless steel pipe and CJ/T152 Stainless steel press-fitting industry standards.
2001 National Science and Technology Promotion Center of China Technology Market Management released on the promotion of application "of height to 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 fully affirmed that the popularization and application of technology and products, will improve the grade of modern architecture, improve and protect the water quality is of great significance.
January 2, 2003 the Ministry of Construction released the "National civil engineering design measures" in the notification, that "priority should use thin stainless steel pipe steel pipe."
July 10, 2003 General Administration 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.
September 25, 2003 China Engineering Construction Standardization Association released CECS153-2003 thin-wall stainless steel water supply pipeline construction engineering.
Beijing Water Corporation [2003] Document No. 194: Prohibition of the Use galvanized pipes, to promote the use of stainless steel pipe, copper pipe was excluded.
January 1, 2004 after the new building materials through water audits, does not meet the requirements of the non-acceptance through the water.
July 12, 2004 the Ministry of Construction approved by the Architectural Design and Research Institute of Tongji editor of the "building water supply metal pipe installation - wall stainless steel pipe" (04S407-2) for the National Building Standard Design, from August 15, 2004 from implemented.
Some aluminum products export tariffs will be reduced to zero import tariffs on aluminum
From the Ministry of Finance was informed yesterday by the State Council, since August 1, 2007 onwards, to form the provisional tax rate will be aluminum import tariff from 5% to 0%; on non-alloy aluminum bars, rods introduction of export provisional tariff, provisional tax rate is 15%.
Ministry of Finance made it clear that the move to further restrict the high energy consumption, high pollution and resource exports, and promote energy conservation, to 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.
The policy for the introduction of the electrolytic aluminum sectors, the analysts 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.
While the aluminum industry since 2003 has been the focus of the national macro-control areas, but high demand by domestic and foreign markets, high prices, high profit-driven, the current alumina and aluminum industry and further expansion of investment and production. This year from January to May, the National electrolytic aluminum output up to 4.832 million tons, up 38%, has increased 22.6 percentage points. At the same time, alumina production reached 7.591 million tons, up 56.2%.
