我厂硫磺尾气装置自八○年开工以来,工艺管线、设备遭受严重的腐蚀、原尾气炉出口的冷—202的φ108×17毫米的1Cr18Ni9Ti.无缝钢管,使用一个半月就多处腐蚀穿孔,腐蚀速度达56毫米/年,后将列管式冷却器改为空气换热、水洗缸 Since the plant started its plant of sulfur exhaust in 1980, the process pipeline and equipment suffered serious corrosion. The cold-202 φ108 × 17 mm 1Cr18Ni9Ti seamless steel pipe exported from the original tail gas furnace used many times of corrosion perforation for one and a half months, Corrosion rate of 56 mm / year, after the tube cooler to air heat exchanger, washing cylinder
