分析解读哪些因素导致列管冷凝器泄露

人气:0 评论:0 日期:2019-09-25 11:54:36

一、外力危害:列管冷凝器在运送、装置等过程中因为遭到外力的效果,往往会危害露出在外面的钢板外壳,使外壳出现裂纹或其它损坏,初期可能很小,不易被发觉,但运用一段时间后就会渐渐扩展,发作走漏。

1. External force hazards: because of the effect of external force in the process of transportation, installation and so on, the tube condenser will often endanger the steel plate shell exposed outside, causing cracks or other damage to the shell, which may be small in the initial stage and not easy to detect, but after a period of time, it will gradually expand and leak out.

二、磨损腐蚀.有些冷凝器现已运用了多年,钢管壁遭到冷却水内杂质的磨损及物料等的腐蚀,使管壁有必定危害。加上为了去除水垢、泥垢、锈等,每年都要进行1~2次的清洗,也对管壁及管壳形成必定的危害。

2. Wear and corrosion. Some condensers have been used for many years now. The steel pipe wall is corroded by impurities in cooling water and materials, which causes certain harm to the pipe wall. In addition, in order to remove scale, mud, rust and so on, it is necessary to clean the pipe wall and shell once or twice a year, which also causes certain harm.

三、焊接质量差

3. Poor welding quality

大多数情况下,冷凝器的走漏是在端头花板与列管管头的焊缝上。焊缝走漏,只能阐明是焊接质量问题。因为这部分通常是选用手艺电弧焊,其中存在着夹渣、气泡、焊缝不丰满及未焊透等现象。

In most cases, the leakage of the condenser is on the weld between the end plate and the tube head. Weld leakage can only be explained as welding quality problems. Because this part is usually welded by manual arc welding, there are some phenomena such as slag inclusion, bubbles, not full weld and not penetrated.

四、钢管质量差

IV. Poor quality of steel pipes

有些时分咱们发现列管间物料从列管口冒出,这阐明管壁有破损,物料从管口漏入管内,再从管口冒出来。列管式冷凝器露出在外面的是钢板外壳,列管均匀分布在壳体内,并两端焊接在壳体两端的花板上,列管不会遭到外力的危害。

Sometimes we find that the material between the rows rises from the nozzle of the rows, which indicates that the wall of the tube is damaged, and the material leaks into the pipe from the nozzle and then comes out from the nozzle. Tube condenser is exposed to the outside of the steel plate shell. The tube is evenly distributed in the shell, and both ends are welded on the ceiling at both ends of the shell. The tube will not be harmed by external forces.
