Affected by the financial crisis and economic recession, the United States has frequently used trade remedy measures since 2009. A new study by Chad of trade restrictions imposed globally in 2009, such as countervailing, anti-dumping and special protection, increased by 29.5% compared with 2008. Trade protectionism measures have become an important hidden trouble affecting the world economic recovery.
Domestic pipes are mainly made up of hot rolled or cold drawn and root carbon welded pipes. Precision tubes are usually used under high temperature and high pressure conditions. When pipes are used as boiler tubes for high temperature flue gas and steam, they will be oxidized and corroded. The steel pipe is required to have high durability, high oxidation resistance, corrosion resistance and good microstructure stability. According to the high temperature performance of boiler tubes, the boiler tubes are divided into common boiler tubes and high-pressure boiler tubes. General boiler tubes or high pressure boiler tubes can be divided into various types of pipes according to their needs.高压锅炉用无缝钢管（GB5310-2008）是用于制造高压及其以上压力的水管锅炉受热面用的优质碳素钢、合金钢和不锈耐热钢无缝钢管。5.化肥设备用高压无缝钢管（GB6479-2000）是适用于工作温度为-40~400℃、工作压力为10~30Ma的化工设备和管道的优质碳素结构钢和合金钢无缝钢管。精密管制造方法一般精密管在350℃以下使用。
精加工钢管的生产工艺与普通无缝钢管相同，是酸洗、冷轧多道次工序。产品可为粗铸件或冷件。2。精密钢管是近年来出现的产品，主要是内孔和外壁的尺寸具有严格的公差和粗糙度，外径较小。Jiangsu Shagang lowered the factory price of steel in the middle of this month, in which the price of heat preservation and anti-corrosion steel pipe was reduced by yuan and the price Shagang has a certain benchmarking role in the heat preservation and anticorrosion steel pipe market, its price has been greatly reduced, domestic mainstream steel enterprises have introduced price
It can be said that, to a certain extent, this is because of excessive interference and other local power from the private interest, the steel industry not only delayed the transfer to the upstream of the industrial chain to achieve the goal, but also made the T overcapacity In this regard, the problem of overcapacity in the steel industry has not been alleviated. In essence, it should be a question of the relationship between power and market, whether the market should play a decisive role or not.
