Will there be any problems with the leakage of the carbon steel kettle jacket

Regardless of whether the jacket is leaked internally or externally, it is not allowed. Needless to say, if there is a chemical reaction with the substances in the kettle, the consequences are unimaginable; Jackets are usually set up for functions such as heat preservation, heating and cooling, and in some designs, if they are equipped with load-bearing parts such as legs, bearings, etc., they also serve the function of fixing the equipment. In order to prevent the corrosion of carbon steel equipment, chemical components such as corrosion inhibitors will be added to the refrigeration medium such as frozen brine, such as potassium dichromate (sodium), liquid alkali, etc., and these chemicals have certain chemical corrosiveness and toxicity to the human body. Some other heating media are also hidden dangers to people, and leaks can also cause energy loss, so leaks should be repaired as soon as possible.

If it is only a leak in the weld, it is sufficient to repair the equipment after it is empty, while in other locations, the jacket wall thickness needs to be checked to determine and assess the corrosion status of the equipment, and if there is a leak touching the supporting parts of the equipment, it needs to be checked together to avoid leaving hidden dangers.

No, the reactor jacket is two layers, and there is a medium in the jacket to maintain the reaction temperature, and the reactor barrel generally refers to the actual volume inside the reactor. Therefore, there is a difference between the two, and of course it is not excluded that the reactor and the reactor cylinder are mixed up as one concept.

They can be welded by welding, but you have higher requirements when welding, because the stainless steel pipe surface at the weld inside the jacket and stainless steel sleeve is easy to be leaked by the arc during welding and weld trachoma or fine seams, and it is difficult to find when you test the pressure to check the leak, because once you can't find out, if all the pipes are connected, if the weld in the jacket leaks, you can't see it outside, and then you can't find out which leak is at all, so once it leaks, it's very troublesome. Moreover, the material of carbon steel pipe and stainless steel pipe is different, and the expansion situation is different during the heating and cooling process, and the weld is easy to tear apart, causing leakage of different degrees.

Intergranular corrosion should occur between carbon steel and stainless steel.

A lot of heat exchangers are not all heat exchange tubes go through the process medium, and water goes between the heat exchange tubes and the walls of the container, you said.

No problem.

No problem, the middle is basically contacted by support.

What you want to ask is what kind of connection can be used to make the carbon steel and stainless steel pipes work together in this system?

Isn't it okay to use pipe fittings to connect, it doesn't have to be welded.

I hope you can be more detailed, maybe I'll give it to you.

Intergranular corrosion should occur between carbon steel and stainless steel.

Allusion In the last years of the Qin Dynasty, Zhang Han, the general of the Qin army, attacked the state of Zhao. The Zhao army retreated to Julu (southwest of present-day Pingxiang, Hebei) and was heavily surrounded by the Qin army. King Chu Huai then named Song Yi as a general, and Xiang Yu as a deputy general to lead the army to rescue Zhao.

After Song Yi led his troops to Anyang (now southeast of Cao County, Shandong), he did not move for 46 consecutive days, and was very uneasy about this feather, so he asked to march to a decisive battle to relieve the Zhao State. However, Song Yi hoped that after the battle between the Qin and Zhao armies, the Qin army would not attack until the Qin army was exhausted.

But at this time, there was a shortage of food and grass in the army, and Song Yi was still drinking and taking care of himself, Xiang Yu saw that he couldn't bear it, and entered the camp to kill Song Yi, and claimed that he was treason against Chu. So the soldiers supported Xiang Yu as the general. Xiang Yu's killing of Song Yi shocked the Chu State and made him famous among the princes.

Subsequently, he led all his troops across the Yellow River to rescue Zhao and relieve the siege of Julu. After Xiang Yu crossed the Yellow River with the whole army, he ordered all the ships to be scuttled, the pots used for cooking rice were broken, his barracks were burned, and he only brought three days of dry food, so as to vote to fight to the death, and there was no intention of retreating.

It was in this way that the army, which had no way out, reached the periphery of Julu, and surrounded the Qin army and cut off the passage of the Qin army's external communication. The soldiers of the Chu army were ten with one, and the killing sound was earth-shattering. After nine fierce battles, the Chu army finally broke the Qin army.

However, the other princes who came to reinforce him did not dare to approach because of timidity. The courage and skill of the Chu army greatly increased Xiang Yu's prestige. So much so that after the victory, when Xiang Yu met with the princes from all walks of life at Yuanmen, the princes did not dare to look at Xiang Yu directly.

Later, "all shipwrecked, broken cauldrons" evolved into the idiom "broken cauldron and sunken boats", which was a metaphor for fighting to the death, and the determination was great.

See upstairs for the story.

Youlian: Where there is a will, there is a way, the cauldron is broken, and the one hundred and two Qin passes belong to Chu after all;

The hard-working people do not live up to the sky, and the salary tastes the gall, and the three thousand Yuejia can swallow Wu.

It's good to put it on the kettle, but it doesn't cost a lot of money to add two fixed frames to the tower on the floor, the key is safety. View the original post
