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。

山东大鼎金属材料有限公司From a positive point of view, the market is still in weak integration. Price adjustment policies, as the weather warms, are slowly reviving the industry; if raw materials do not show too much volatility, it is difficult to fall again, because the market is less profitable and expected to be higher, so alloy tubes will be very strong after a tentative pull on the market.
