The boiling soup was a kind of soup with an extremely high temperature. It can be used to describe hot water or hot food. Boiling soup was a kind of steaming, warm and delicious liquid that was often used to cook all kinds of soup-type dishes. It could be made from different ingredients. It had a rich fragrance and taste, which could add rich flavor to dishes. However, there were some precautions to take when drinking boiling hot soup. The human mouth, esophagus, and gastric mucus could only withstand a maximum temperature of 60 ° C. If the temperature exceeded this temperature, it would cause burns to the mucus. Therefore, one should pay attention to the temperature when drinking soup to avoid burns.

The material standard of the chemical plant reactor pipeline is affected by many factors, such as corrosion resistance, strength, temperature resistance, etc. Different materials have different characteristics and scope of application: 1. ** Cast iron pipe ** - Ordinary cast iron pipe: It has good corrosion resistance to soil, acid, and alkali-based materials. It is mainly used for underground water supply main, gas main, sewage pipe, etc., but it has low strength and high fragility. It cannot be used for pipes with high pressure or toxic or explosive media. - Ferro-iron pipe: High Ferro-iron pipe can resist the corrosion of a variety of strong acid, high hardness, difficult to process, fragile by vibration and impact; anti-corrosive iron pipe can resist the corrosion of various temperatures and concentration of sulfuric acid. 2. ** carbon steel pipe **: generally not corrosion-resistant, in specific occasions such as concentrated sulfuric acid, room temperature soda can resist a certain degree of corrosion, but not suitable for chloride-ion-containing occasions, sensitive to stress corrosion. 3. ** stainless steel pipe ** - ** Austenite stainless steel ** - **304 stainless steel **: The most commonly used. It contains a small amount of chromium-based and nickel-based metals. It has a low carbon content, is easy to heat treat, and has good high temperature resistance (the general use temperature limit is less than 650 ° C). It has excellent stainless corrosion resistance and good intercrystalline corrosion resistance. It has good corrosion resistance to oxidistic acid (in the concentration of <65% in the boiling temperature of the sulfuric acid), basic solution, and most organic and mineral acid. However, it was particularly sensitive to the medium containing the chloride-ions in the solution and was prone to stress corrosion. - ** 304L stainless steel **: Low carbon version of 304, mainly for the carbon penetration of 304 steel. The lower carbon content minimized the precipitations of carbon near the heat-affected zone of the welding line, reducing the possibility of intercrystalline corrosion (welding corrosion) in certain environments. - **321 stainless steel **: Ni -Cr-Mo type Austenite stainless steel. Its performance is similar to 304. Adding titanium makes it have better grain boundary corrosion resistance and high-temperature strength. It has excellent high-temperature stress breaking performance and high-temperature creep resistance. It is used in outdoor machines in the chemical, coal, and oil industries that require high grain boundary corrosion resistance, heat-resistant building materials, and parts that are difficult to heat treat. - **316 stainless steel **: With Mo added, the corrosion resistance, atmospheric corrosion resistance, and high-temperature strength are particularly good. It can be used under harsh conditions. The corrosion resistance is better than 304 stainless steel. It is resistant to the corrosion of the ocean and corrosive industrial atmosphere. It has a certain degree of corrosion resistance to diluted sulfuric acid and solutions containing chloride-ions. It is more resistant to corrosion than 304 in high-temperature environments. - **316L stainless steel **: The carbon content is far lower than 316. It is widely used in important working conditions in the chemical industry (because the high carbon content is the main factor that causes intercrystalline corrosion of metals). It is better than 316 in terms of corrosion resistance to chloride-ions, but the price is higher. - High-alloy stainless steel: 29% - 30% Ni, more than 20% Chromium-based, good corrosion resistance to acid and sulfuric acid, but expensive. 4. ** Monel tube (Ni alloy): It was a corrosion-resistant alloy with the largest amount of usage, the most extensive use, and excellent comprehensive performance. It had excellent corrosion resistance in the media of fluorodic acid and fluoric acid, and also excellent corrosion resistance to hot concentrated soda liquor. At the same time, it was also resistant to corrosion of neutral solutions, water, seawater, atmosphere, organic compounds, etc. Generally, it did not produce stress corrosion cracks, and had good cutting performance. The applicable temperature could reach 500 ° C. It was more expensive than stainless steel, but it was not sensitive to stress corrosion cracking in the environment of chloride-ions. 5. Hastelloy alloy pipe (nickel-based alloy): currently divided into three series B, C, G, mainly used for iron-based Cr-Ni or Cr-Ni- Mo stainless steel, non-metallic materials and other unusable corrosive media. It has been widely used in many fields such as oil, chemical industry, environmental protection, etc. 6. <strong></strong><strong></strong> In addition, for the material selection of the heating tube of the reaction kettle mold temperature machine, if the mold temperature machine uses water as the heat transfer medium, it is recommended to use 316 stainless steel; for the ultra-high temperature mold temperature machine, 321 stainless steel can be used. At the same time, in the selection of chemical pipeline materials, according to the SH3059 standard, materials with a corrosion rate of less than 0.05mm/a were sufficiently corrosion-resistant materials; materials with a corrosion rate of 0.05 - 0.1mm/a were corrosion-resistant materials; materials with a corrosion rate of 0.1 - 0.5mm/a were corrosion-resistant materials; materials with a corrosion rate of more than 0.5mm/a were corrosion-resistant materials. This was also the standard related to corrosion rate that needed to be considered when selecting the material of the reactor pipeline. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The story of a young inventor usually described a young inventor who kept experimenting and creating new things as he grew up and eventually became an outstanding scientist or entrepreneur. This theme appeared in many novels and movies, such as the Harry Potter series and the Matrix series. In the story of a young inventor, there was usually an important family or community background that provided the protagonist with an opportunity to grow and develop his creativity. The protagonist may face many challenges and difficulties such as learning difficulties, family problems, social isolation, etc. However, he or she will usually overcome these obstacles through continuous hard work and creativity and eventually become a successful inventor or inventor. The stories of the young inventor often touched on topics of technology, innovation, creativity, and self-actualization, as well as the importance of family, community, and interpersonal relationships. These stories often inspire readers and audiences to explore their own potential, try to be creative, and break through to become a better person.

The origin of the novel is complex and can't be traced to one specific inventor. It emerged gradually as a literary form with influences from various cultures and periods.

It's hard to attribute the invention of the novel to a single person. Novels have evolved over time through the contributions of many writers and storytellers.
