In the development of new technology and new sales channels all have various shortcomings of modest, are now calls for energy conservation and emissions reduction.The completely is the process of marketization.Need of special note is many of our export market is the basic product steel, must rely on imports.
China seamless steel tube industry has never been positioned as a supporting industry exports, after decades of efforts to achieve self-sufficiency, until 2005 to achieve the balance of imports and exports, has been into greater than before, completely is the process of marketization.Need of special note is 70% of our export market is the basic product steel, must rely on imports. We even exported to some developed countries, steel varieties overall are complementary to each other. However, a few years ago, we took the initiative to export some of the export duties were imposed on seamless tube varieties. Part of our export products seamless tube adopted restrictions. Our ASTM A106 Seamless Steel Pipe products export is completely implemented by comparative advantage, by competition, no subsidies.
In the construction industry, the large steel structure is developing rapidly, structure of steel structure is more and more abundant, the new technology and the new materials are used more widely.For the steel structure industry, from the material being very environmental protection, construction, beautiful shape, construction technical difficulty, the respect such as the welding work comprehensive consideration, in order to realize the low cost to build green, environmentally friendly buildings.
According to the reporter investigation of spiral steel pipe industry now cost is high, resulting in products are not competitive, in the development of new technology and new sales channels all have various shortcomings of modest, are now calls for energy conservation and emissions reduction, environmental spiral steel pipe outlet may be here, to the spiral steel pipe with high and new technology in environmental protection now hope can gain a foothold in the emission reduction and energy saving.The next step is for the country to be able to make seamless pipe production, but the price is still determined by the market.In the next phase, it may be possible to look at the progress of such work, such as the clampdown on floor steel, when there may be a rebound in the price.
China seamless network points out that overcapacity is relative to demand.On the supply side, it is hard to find a truly global product.China's seamless pipe capacity is dominated by domestic demand, which accounts for nearly half of the world's output, but consumes nearly half as much."Our seamless steel pipe exports accounted for the proportion of production, the highest of the year and only around 13%, and some countries have already more than 40%.So, for China's seamless tube excess capacity must be very rational view, size itself is not the problem, it depends on whether the fair competition, ultimately depends on competitiveness.
What are the precautions for storing seamless steel pipes?
1. Choose a suitable venue and warehouse; 2. Reasonable stacking, advanced first; 3. Packaging and protective layers of protective materials; 4. Keep warehouse clean and strengthen material maintenance.Significance of Proximity Effect on the Production of High-frequency Longitudinal Welded Pipes
In addition to the skin effect, the proximity effect is another feature of current. When alternating currents of equal magnitude and opposite directions pass through two adjacent conductors, the current will flow through the adjacent inner surface layers of the two conductors, and when the two conductors pass When alternating currents of the same size and direction, the current will flow through the outer surface layers of the two conductors. The proximity effect of the current makes the current in the conductors further uneven. It is this unevenness that makes the high-frequency welded pipe(ERW).Summary of Advantages and Disadvantages of High-Frequency Welded Pipe Forming Methods
