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。
Perhaps it is for this reason that in the past quite a long time, on the other hand, despite many warnings from the parties concerned, the excess capacity of the steel industry, and even industrial restructuring, the local government still avoided the iron and ST through the "zero" policy response is the eel project; at the same time, in order to safeguard the economy. Protecting the contribution of related steel production capacity to local GDP, some places have spared no effort to support local backward production projects even if they clearly know that steel production in some places is significantly backward and policies are biased.山东大鼎钢管厂、山东大鼎金属材料有限公司
It can be said that, to a certain extent, this is because of excessive interference and other local power from the private and more serious. In this regard, the problem of overcapacity in 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.
