锆管在双氧水制取设备中作蒸发管。经受强烈的腐蚀,常有穿孔与凹坑,需修复。由于锆管稀有昂贵,因而焊接修复的经济价值可观。锆管直径25mm,壁厚1.5mm,使用后的锆管内壁呈凹点状,有的甚至穿孔,壁厚减薄为1.2mm左右,内壁有大量污垢。修复时需将穿孔或凹点多的部位锯掉,按尺寸要求进行修复。 Zirconium tube in the hydrogen peroxide equipment for evaporation tube. Experience strong corrosion, often perforation and pits, to be repaired. Due to the rare and expensive zirconium pipe, the economic value of welding repair is considerable. Zirconium tube diameter 25mm, wall thickness 1.5mm, zirconium tube after use was concave pits, and some even perforation, wall thickness reduced to about 1.2mm, a large number of dirt on the inner wall. The need to repair the perforation or pits and saw more parts, according to size requirements for repair.
