产品描述
参数
1995年我公司同上海材料研究所合作开发了09CrCuSb(企业代号ND)无缝钢管,1997年入选GB150-1998标准,广泛用于高含硫烟气中服役的省煤器、空气预热器、热交换器和蒸发器等设备。由于近些年来进口高硫原油逐步上升,现有ND材料已经不满足大多数炼厂、电厂等企业的实际工况需求。2015年底在中石化洛阳工程有限公司等单位技术支持下,我公司优化了材料合金配比、添加其它微量元素,成品管材通过合肥通用所第三方检测,均匀腐蚀速率小于4mg/cm2.h。
 
In 1995 our company has cooperatively developed 09CrCuSb (enterprise code ND) seamless steel tubes with Shanghai Material Research Institute, which was selected in standard GB150-1998 in 1997, and have widely used in the service of high sulfur in flue gas economizer, air preheater, evaporator and heat exchanger and etc. Due to the gradual increase in imports of high sulfur crude oil, the ND materials could not meet the actual needs of the most refineries, power plants and other enterprises. By the end of 2015, in the technical support of the relevant research institutes, our company optimized the material composition, and added other trace elements, the finished pipes were detected by the third party of Hefei General Machinery Research Institute, which concluded that the uniform corrosion rate was less than 4mg/cm2.h.
 
09CrCuSb(S)优点
优化了合金配比,添加了稀有合金,成品管材具有优良的耐硫酸均匀腐蚀能力,根据合肥通用所第三方检验拫告耐腐蚀性能比原有ND钢提升2倍多;
控制了As、Sn、Pb等五害元素含量,控制氢、氧、氮的气体含量,使坯料纯净度更高,根据多次分析材料晶粒度不粗于8级;
此类材料制作的设备耐腐蚀能力提高,相对延长了炼厂、电厂的检修周期,具有较大的经济效益。
 
Depend on the optimization of the alloy ratio and the addition of rare alloy, thefinished pipes had uniform excellent corrosion resistance to sulfuric acid. According to the third-party inspection reportof Hefei General Machinery Research institute, corrosion resistance of the ND steel has increased two times than the original steel;
Controlling the content of five harmful elementslike As, Sn andPband the gas content of hydrogen, oxygen, nitrogen made the purity of the billet became much higher. According to many analyses, the grain size of the material was not more than level 8;
This kind of material has great economic benefit which improvesthe
corrosion resistance of the equipment, extends the maintenance cycle of refinery and power plantrelatively.
