There are few people in the township, and there are no people on the streets at nine o'clock, and occasionally cats and dogs suddenly pass by from the shadows, which makes people break out in a cold sweat. Geng Zhiyuan cheered up, carefully observed the surrounding environment, and walked back to the hotel quickly.

After taking a shower, he collapsed on the bed and looked up at the ceiling in distraction.

Tonight's relationship with Wei Xiao is very different from usual, the two of them chatted happily and devotedly, and some embarrassing things that are inconvenient to mention to outsiders dare to take them out and tell each other to each other, the night was short and comfortable, which made people inevitably feel a little uncomfortable.

"Could it be that Wei Xiao and I can develop into love?" a bold idea suddenly popped up in Geng Zhiyuan's heart.

"Impossible!" he shook his head vigorously and laughed at himself: "Wei Xiao has always disliked me, how can he talk to me about feelings? ”

"That Teacher Yu must have an idea about Wei Xiao, maybe if I don't show up, the two of them may be able to become a couple. Geng Zhiyuan thought wildly: "Just like Wang Chenguang, he knew that I liked Wei Xiao so he didn't want to, so he came to trouble me." ”

Geng Zhiyuan turned over, lay on his side on the bed and said secretly: "Maybe I shouldn't have gone to Wei Xiao, which affected the marriage between Teacher Yu and her." That's it, I won't go to her from tomorrow onwards, so I don't have to mess up other people's good things. ”

It's a pity that when he thought of Wei Xiao living with Yu Haiyang, Geng Zhiyuan felt uncomfortable. After turning over a few times, he had to sit up in frustration: "No, why give Wei Xiao to him for nothing." Since I still like her, why don't I try it? If I succeed and get my long-cherished wish fulfilled, my life will not be in vain. ”

"But ......" Geng Zhiyuan scratched his head in embarrassment: "If it really happens, I can't leave Wei Xiao here alone." How do you get her to the provincial capital?...... Alas, I'm a little engineer, I'm in a foreign land, and I don't know anyone other than my classmates, so I really can't think of any good way. ”

"It's hard!" he sighed, and fell asleep on the bed in a daze.

Early Thursday morning, as soon as Zhang Shulin entered the office, he picked up his helmet and said to Geng Zhiyuan: "Xiao Geng, let's go, let's go to the scene to have a look." ”

Geng Zhiyuan took on the hard hat, followed Lao Zhang out of the chief engineer's office, and walked towards the nitric acid project site.

Walking to no one's place, Zhang Shulin suddenly turned around and asked, "Zhao Liangsheng made trouble for you yesterday?"

Geng Zhiyuan was stunned: "Oh, it's nothing, a little bit of electrical professionalism." ”

"Well...... Zhang Shulin nodded, "Your attitude is right." Society is different from school, everyone has it. It is true that people should talk about feelings, but they should pay more attention to interests. There is a way that Saiong knows whether he is blessed or not, Lao Zhao is embarrassed by you, if you look at it from another angle, it is also exercising you. Measure it bigger, there are some things that you can't care about. ”

"I understand, thank you Mr. Zhang for your advice. Geng Zhiyuan thanked him from the bottom of his heart.

Zhang Shulin laughed and said: "Seeing you is like seeing me when I was young, working hard while I was young, this world still belongs to you young people after all." ”

"Hmm!" Geng Zhiyuan felt warm in his heart, as soon as he joined the work, he met Lao Zhang, who was willing to teach young people to grow up, which was really a great blessing in life.

"Mr. Zhang, there was a fight between the pipeline and the civil beam on the site. As soon as I arrived at the construction site, Manager Shen, the person in charge of the 16th Chemical Construction Project, hurried over and said.

Zhang Shulin frowned: "Which pipe?"

Manager Shen opened the drawing in his hand and pointed out: "The DN300 vapor phase tube from the oxidation furnace collided with the diagonal brace beam of the plant when it passed through the wall. ”

"Go check it out. Zhang Shulin glanced at the drawings and turned his head towards the ammonia oxidation plant.

Coming to the ammonia oxidation furnace on the second floor of the ammonia oxidation plant, Geng Zhiyuan looked up and saw that a thick pipe coming out of the top of the oxidation furnace went straight to the south, and happened to collide with a diagonally bracing steel beam on the south wall of the plant.

"Xiao Geng, you talk to the courtyard to see if you can raise the pipe or remove the diagonal brace. Zhang Shulin commanded Geng Zhiyuan.

Geng Zhiyuan hurriedly nodded and responded, "Okay, I'll call when I go back." ”

"You have to be cautious about elevating. Zhang Shulin looked at it carefully for a long time, and thought with his hands behind his back: "As soon as the tube grows, the gas residence time will be longer, and the condensate acid cooled down by the subsequent condenser will increase." Not to mention that the condensate acid is more corroded to the pipeline, it will also affect the absorption effect of the absorption tower, and the final concentration of the finished acid will decrease. ”

"Well, I'll tell him to think about it. Geng Zhiyuan took out a notebook from his backpack and briefly wrote down Lao Zhang's views.

"Manager Shen, is there anything else?" Zhang Shulin asked again.

Manager Shen thought for a while and said, "Civil engineering reflects that there are several pipe frame foundations and drainage ditches fighting, and they have been translated. In addition, a pump did not come, and the factory had to urge again. ”

"Okay, you have people reflect the matter of the pipe frame to Geng Gong in writing, and it must be confirmed by the design institute. Zhang Shulin said again: "I'll urge the pump." ”

"Good. Manager Shen looked at Geng Zhiyuan and sighed: "Geng Gong, you are so young." ”

Geng Zhiyuan had to say modestly: "Please ask Manager Shen for more advice." ”

"Don't dare to advise, anyway, there will be a lot of trouble for you in the future. Manager Shen pointed to the pipeline materials piled up on the ground: "Our technician is right, many pipeline materials on your drawings are not accurate, and we have to trouble you to check and make a change when the time comes." ”

"Okay, okay. Geng Zhiyuan only felt a headache, there are so many pipelines in one project, if you really check them one by one, the workload will be too large.

"Xiao Geng hasn't been to the scene, what do you think this is?" Zhang Shulin picked up a stainless steel flange from the ground.

Although Geng Zhiyuan did not learn flanges when he was in school, he already knew flanges when he went to Haixi for on-site practice, and immediately replied: "It's flanges, stainless steel, right?"

Zhang Shulin smiled: "It's a flange, let me ask you what form of flange you are?"

Geng Zhiyuan took the flange and looked at it carefully, noticed that there was a boss in the inner ring of the flange, shook his head and said: "I don't know, I haven't learned several flanges with different structures." ”

"This is a flat weld flange with a neck. Zhang Shulin pointed to the boss and said: "This is the so-called neck, put it into the pipe end, and weld the edge of the boss with the pipe wall flat, so it is called the flat welding flange with neck." ”

"Oh, I see!" Geng Zhiyuan touched the flange boss with his hand, and said in his heart: "Although the scene is hard, the harvest is also very large, if you just stay in the design institute to talk about the army, where will you know that the neck flange is like this? It seems that the scene can combine knowledge with practice, which is very beneficial to the improvement of their design level." ”

Zhang Shulin took a valve and told him: "This is a globe valve, you can see that the size and pressure level are written on the valve body. ”

"What does this PN16 mean?" Geng Zhiyuan asked, pointing to the number on the valve body.

PN16 means that the pressure rating of the valve is 16 bar, which is about 1.6 MPa. Zhang Shulin took another valve and said: "This is a ball valve, which can be seen from the appearance is different from the globe valve." ”

He pointed to a flat valve lying on the ground and said: "This is a butterfly valve used on the water supply and drainage pipeline, and its valve surface is a plate, which rotates like a butterfly wing, so it is called a butterfly valve." ”

The butterfly valve body is very short and suitable for large diameter pipes. Geng Zhiyuan squatted down and touched the valve and said, "Mr. Zhang, this valve is much more difficult to open." ”

"Of course, some large valves have to be rotated by motors, and people can't pull them at all. Zhang Shulin taught step by step: "You can usually come to the scene to see more details, otherwise an engineer doesn't even know the valve flange, and people will laugh at him." ”

"Hmm!" Geng Zhiyuan said in his heart: "Just use this opportunity to figure out these things like flanges, otherwise independent design projects will really be laughed at in the future." ”

Back at the Chief Engineer's Office, Geng Zhiyuan took off his helmet, quickly called Wang Ping's phone, and told him all the problems reflected on the scene.

Wang Ping on the other end of the phone pondered for a while before saying: "I will discuss the matter of the gas phase pipeline with civil engineering and then decide how to change it." For those pipeline materials that they think are problematic, you send them by fax, and I ask the designers of each section to check them separately. ”

"Okay, I'll pass it on to you as soon as the chemical construction company gives it to me. Geng Zhiyuan secretly rejoiced that he had escaped, if Wang Ping asked him to check the pipeline materials on the spot, it would be a big project.

In the midst of the busyness, the morning passed quickly. Seeing that it was almost time to get off work, Zhang Shulin suddenly asked, "Where is Xiao Geng's hometown?"

"My family is here, living in Hexi District. Geng Zhiyuan replied truthfully.

Li Ying was surprised: "Are you from our place?

The local dialect of Liangcheng is relatively hard, which is obviously different from the surrounding counties and cities. Geng Zhi has been away from home for many years, and he has long been accustomed to speaking Mandarin, and only when he gets along with his parents can he inevitably speak the local dialect.

"I usually speak Mandarin. ”

"Tomorrow is the weekend. Why don't you go home and have a look?" Zhang Shulin said with a smile: "Our factory has a shuttle bus directly to the city, and it is very convenient to go back and forth." ”

"Really, great!" Geng Zhiyuan was happy, and suddenly had a bold idea.

"Mr. Zhang, how do you sit on the shuttle bus in the factory?" Geng Zhiyuan asked anxiously.

Zhang Shulin said: "Our employees have a car card. In the afternoon, I will take you to Director Chen and ask the factory office to issue you a letter of introduction, and you can take it to the driver. When I get acquainted with you in the future, I don't need to read the letter. ”

Geng Zhiyuan sank and asked, "What if I take another classmate to take a car?"

"Classmate?" Zhang Shulin glanced at him suspiciously, and said with a smile: "It can't be a female classmate, right?"

Geng Zhiyuan's face flushed: "It's a female classmate, she is a teacher in the town middle school next to our factory, I want to ......"

Li Ying was surprised when she heard this: "You can't be talking about Teacher Wei, right?"

Geng Zhiyuan looked at her and was a little stunned: "Yes, my classmate's surname is Wei, how did Sister Li know?"

"Among the young teachers in the town middle school, only Ms. Wei's family is in the urban area, and I guessed that it was her as soon as you said it. Li Ying said with a smile on his face: "Geng Gong is young and promising, and he is in the Provincial Design Institute, and he is a talented and beautiful pair with Mr. Wei, you have to seize this opportunity." ”

"No, no, no!" Geng Zhiyuan's face turned red, and he waved his hand again and again to explain: "You guys think it's bad, I am just classmates with her, and we have nothing else to do with it." ”

Seeing that he was so eager to confess, several people in the chief engineer's office laughed. Zhang Shulin patted his thigh and said, "Teacher Wei is a town middle school...... No, there is a flower in our town, and many young men in the factory are worried, you and she are classmates, why don't you hurry up and chase her?"

"That's it!" Liu Ruogu smiled kindly: "If you miss such a good opportunity, don't regret it in the future." ”

Zhang Shulin said proudly: "You don't have to worry about the shuttle, just write two people when the factory office opens a letter of introduction." It's not easy to get back to the city from us, so if you can help someone, you can help. ”

"Yes. Li Ying said excitedly: "It's a pity that a beauty like Mr. Wei stays in our town, Geng Gong hurries to catch up with others, saving so many people in the factory from worrying." ”

"I ......" Geng Zhiyuan was stammered by what everyone said, and he couldn't defend it for a while. I didn't expect Wei Xiao to be so famous in his hometown, it seems that Geng Zhiyuan wants to take this beautiful flower away, I'm afraid he will encounter some inexplicable resistance.
