Cold rolled non decarbonization cold rolled strip was annealed under protective atmosphere. The protective atmosphere consists of a single inert gas, argon or helium, but also includes mixed gases. By adjusting the composition of these mixed gases, the speed of redox, decarbonization and Carburization in the annealing process of strip steel is equal, so as to realize the non-oxidation and non-decarbonization annealing of strip steel. After annealing, bright precision tubes should be decarburization. The annealing factor of the bright tube depends on the atmosphere and redox reaction. And other inert gases are neutral protective atmospheres of steel. It is widely used, but the oxygen atmosphere must be removed to play a good protective role. Commonly used mixed protective atmospheres.结构用无缝钢管（GB/T8162-2008）是用于一般结构和机械结构的无缝钢管。流体输送用无缝钢管（GB/T8163-2008）是用于输送水、油、气等流体的一般无缝钢管。内外涂塑复合钢管是以焊接钢管为基材 可在受污染的海水光亮精密管退火可保持光亮管的外观精度，尺寸精度高，越来越受到客户的青睐。
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。
山东大鼎钢管厂This is good for steel demand, including insulation and corrosion resistant tube mill cold-drawn (rolled) seamless steel pipes: round billet heating, piercing, tapping, annealing, pickling coating (copper) multi-pass cold-drawn billet tube heat treatment, straightening, water pressure test mark storage. Hot-rolled steel pipe is composed of continuous casting slab or blooming slab. It is heated by walking beam reheating furnace and descaled by high-pressure water into roughing mill. The rough material is cut into the head and tail and then enters the finishing mill, which is controlled by computer. After finishing rolling, the coiler is coiled into a straight coil through laminar cooling. The head and tail of straight curly hair are usually tongue shaped and fishtail, with poor accuracy 不锈钢厂出口价格没有上涨，钢材贸易促销利息反弹飞涨，价格形势严峻，利润微薄，企业销售一直无法打折，并且价格认可”加强，主要维持稳定。但是，随着经济条件的恶化，国民经济体制一般会保持无序，难以发挥很大的优势。上周，电线和指纹报价系统主要是平价和折扣；上周，冷轧、热轧和中板报价主要是战盘，但单位钢报价也略有下降。消费和资本注入正在改善，通胀压力正在下降，这为进一步放缓提供了更好的基础，
