After Labor Day, the pressure pipeline certification expert audit team was stationed in Donghai Provincial Chemical Design Institute and began to review the application for GB, GC and GD pressure pipeline certification submitted by the Provincial Chemical Industry Institute.

Han Yingjie gave Geng Zhiyuan two main tasks, one is to demonstrate the operation of stress analysis software to the experts, and the other is to answer questions about stress analysis and pipeline materials during the defense.

The members of the expert group are all veterans who have been engaged in process design for many years, and although they have very rich engineering experience, they are not very proficient in stress analysis. They watched a demonstration of the software in operation, carefully checked the relevant calculations, and asked a few questions.

One of the most important aspects of the forensic examination is the defense. The expert group selects several representative projects, asks questions about the problems existing in the drawings, and the design, verification and reviewers of the drawings will answer.

The transformation section of the ammonia plant in charge of Kou Wanshan was selected, and the experts raised a question based on the drawings, why is it necessary to increase the pressure level of the pipeline as the temperature rises under the same operating pressure?

Kou Wanshan and the others didn't know how to answer for a while, Geng Zhiyuan had to answer: "According to the temperature and pressure curve on the HG20592, with the increase of temperature, the allowable pressure value of the flange decreases, so the pressure level needs to be increased. ”

The experts listened and said, "Yes, that's why." Therefore, we must pay attention to the temperature when selecting materials in the design, especially the selection of the pressure level at high temperature. ”

The next thing that was drawn was the dilute nitric acid section of the Haibin County Nitric Acid Project that Wang Ping was in charge of, and the question raised by the experts was whether the expansion joints set on the tail gas pipes from the oxidation furnace were intended to absorb axial or lateral displacements.

Wang Ping never understood the role of the expansion joint on the exhaust pipe, and replied vaguely: "Axial displacement." ”

The experts were stunned and continued to ask: "Since it is axial displacement, why are there no fixed frames at both ends?"

"Ah...... This?" Wang Ping opened his mouth and was dumbfounded, and Liang Guangyuan, who was sitting next to him, scratched his head in a hurry, but there was no way to respond.

Geng Zhiyuan had no choice but to raise his hand again and replied: "What is absorbed is the transverse displacement, and two transverse displacement expansion joints are arranged at an angle of 90 degrees to cooperate with the absorption of transverse displacement in both directions." ”

The experts couldn't help but nod and said, "This little comrade is still right." ”

Geng Zhiyuan helped the two project teams out of the siege in a row, and said in his heart: "With such a big design institute, you can't just rely on me as an assistant engineer to answer questions and solve problems. ”

Fortunately, the latter questions were not too difficult, and the project team members were able to deal with them, and finally successfully passed the defense.

The forensic review took a full week and was completed on Sunday afternoon. In the evening, Lin Chu, who returned to Ningcheng from Yunnan, invited him to dinner, but Geng Zhiyuan didn't have time to go home, so he rode a bicycle and went directly to Zuihuju.

Lin Chu saw that he was coming alone, and said curiously: "What's the matter, the little housekeeper of your family can rest assured that you will come by yourself?"

Geng Zhiyuan explained: "Su Qing has a rehearsal at night, what kind of art show is they going to do, and they arrange for her to participate in a dance performance, which seems to be called Danxian Lotus." There is a rehearsal tonight, and I can't ask for leave. ”

"Danxian lotus?" Lin Chu smiled: "That's a very interesting dance, I also danced." The shape is very down-to-earth, and you had better appreciate it when you have the opportunity, which is sure to open your eyes. ”

"Oh?" Geng Zhiyuan didn't know anything about dancing, and hearing Lin Chuyi say it aroused his interest: "I'll go to the school to take a look at it later." ”

After chatting, Su Qing began to talk about business, Lin Chu said: "You handled the matter of Ningcheng very well, I didn't expect Fu Yousi to become like this, which made me so faceless." ”

Geng Zhiyuan smiled indifferently: "As the saying goes, mercy is not in charge of soldiers, and righteousness is not financial management." For the sake of money, brothers can turn against each other, husband and wife may become enemies, you are just classmates, it is not unusual for her to do this kind of thing. ”

"Zhiyuan. Lin Chu supported his chin with both hands, stared at Geng Zhiyuan with affection and said, "I've known you for almost three years, and I find that you are becoming more and more attractive as a man." ”

Geng Zhiyuan was taken aback, so he had to prevaricate: "According to what you say, I wasn't a man three years ago?"

Lin Chuwan smiled, shook his head and said, "At that time, although you were excellent in all aspects, you were still a little dull, but I still like it." Now...... The charm of maturity with being in control of everything fascinates me more and more. ”

"Chu Chu, you better hurry up and find a partner. You're such a teaser, sooner or later I'll make a mistake. Geng Zhiyuan remembered Wei Xiao's lesson not long ago, and reluctantly persuaded him.

When Lin Chu heard this, his eyes suddenly fell into confusion: "I like ...... I just like to tease you...... I'm not afraid of you making mistakes. ”

"You're not afraid, I'm afraid!" Geng Zhiyuan saw that Lin Chu's face was like a peach blossom, her cheeks were crimson, and he knew that she was moved, so he immediately said categorically: "Chu Chu, you know my personality." Since I am in love with Su Qing, I will no longer love anyone else. Even if I have a relationship with you in a moment of confusion, I can only say sorry to you, and I will never abandon Su Qing and marry you instead. ”

Lin Chu's eyes were gloomy and he said, "I know...... Alas, you're always a love-hate guy!"

"Hurry up and get down to business, I'm going to pick up Su Qing. Geng Zhiyuan lowered his head and tried to avoid eye contact with her.

Lin Chu sighed secretly and said slowly: "I took a look at the financial statements you gave me in the past two days, I didn't expect the tutoring school to be so profitable, I just thought about opening a Chuyuan school in the provincial capital, what do you think?"

Geng Zhiyuan pondered for a while and said, "It's good, but running a school requires people and a lot of professional teachers, do you have a way to find them?"

Lin Chu smiled heartily: "Of course I have a way, otherwise can I think of running a school?"

Geng Zhiyuan glanced up at her and said, "You have to think about it, now these companies have made me scramble, but I can't spare the energy to help you manage the school again." ”

"Don't worry about it, just wait for the money. Lin Chu said confidently.

Geng Zhiyuan secretly said in his heart: "Chu Chu has lived a superior life since she was a child, and she can't help but develop a lofty temperament, and several companies she has invested in rely on me and Lin Zhen to manage, and she has not really experienced the difficulties of running an industry." However, it's better to let her suffer a little loss, so that she doesn't always think about things so simply. ”

"Well, as the chairman of Donghai Chuyuan Education Group Company, I agree with your proposal to open a school in the provincial capital. "Geng Zhiyuan has a reason.

"Go!" Lin Chu saw that he was serious and serious, and said angrily: "Don't be serious in front of me, you really take yourself seriously?"

"The chairman has to have the chairman's style. Geng Zhiyuan deliberately laughed and said: "There are still two female secretaries missing by my side, General Manager Lin, hurry up and help me find a few, I have to pick and choose." ”

"Phew!" Lin Chu chirped: "The more you talk, the more energetic you get, hurry up and pick up your Qingqing sister, be careful of the black state I sue you." ”

The two of them joked for a while, and Geng Zhiyuan saw that the time was close to nine o'clock before he knew it, so he got up and hurriedly said goodbye and left.

Riding a bicycle all the way, I arrived at the performance hall of the Academy of Arts at a quarter past nine. Geng Zhiyuan put away his bicycle and walked into this palace of art with sincere fear.

The performance hall is similar to a movie theater, and there are fifty or sixty people seated in the audience. Geng Zhiyuan saw that Xu Yuan was also there, and quietly slipped to her side.

"Why did you come?" Xu Yuan saw him and said dissatisfiedly: "It's Su Qing's turn soon, and the next one is, you won't be able to see it if you come a little later." ”

"I'm sorry, I'm a little delayed. Geng Zhiyuan hurriedly explained.

While speaking, I heard the beautiful voice of the announcer: "The next show is a fresh lotus, the performer Su Qing and so on." ”

Geng Zhiyuan sneered: "Yes, the rest of the people are all represented by Su Qing." ”

"Watch the show, don't talk!" Xu Yuan said angrily.

Geng Zhiyuan hurriedly closed his mouth and concentrated on watching the performance.

Danxian Lotus is performed by three girls, Su Qing plays the girl with the lotus root as the protagonist, and the other two girls squat to play the lotus root in the basket. As the cheerful folk music sounded, Su Qing carried a load of "fresh lotus" and walked into the center of the stage with cheerful and exaggerated steps.

Geng Zhiyuan saw that his girlfriend was wearing a red folk shorts and pants, a short pink apron tied around her waist, a lotus leaf-shaped hat on her head, and two slender braids on her head.

With the rhythm of light and joy, Su Qing and the other three girls showed the unique slender posture of young girls, and Geng Zhiyuan's eyes were straight: "Good girl! I am with Qingqing every day, why didn't I find that her body was so beautiful when she danced? Could it be that I have been blind to the flowers for a long time?"

Geng Zhiyuan couldn't help but say to Xu Yuan: "Su Qing...... How did I not know about dancing so well?"

Xu Yuan gave him a roll of his eyes: "You, you don't know how to be blessed in the midst of blessings, Qingqing sings, dances and plays the piano very well." ”

"No, wait!" Geng Zhiyuan hurriedly interrupted, "She can also play the piano?"

Xu Yuan rolled her eyes again, and said as if Geng Zhiyuan was an idiot: "Do you really not know or pretend not to know? Qingqing can play the piano and not today, you don't even know? She found you, she really blinded her as a person." ”

Geng Zhiyuan blushed when he landed, turned around and said secretly: "It seems that I am really a little careless, and I don't care enough about Qingqing." She can play the piano? How did I never know?"

When Geng Zhiyuan was wondering, he suddenly remembered the Spring Festival Twelve Arhats gathering last year, when he drank too much wine and went home, when Su Qing accompanied him to comfort him, the song he hummed was "The Piano of the Night".

"Oh! I'm such a bastard!" Geng Zhiyuan blamed himself: "I should have thought that since she likes piano music so much, and she is an art student, she will most likely be able to play the piano, why didn't she think about buying a piano for Qingqing to play?

Looking at his girlfriend's light and flexible dance on the stage, Geng Zhiyuan secretly made up his mind: "I have been busy working and making money for a while in the past, and my communication with Qingqing and my concern for her are not deep enough, I have to make amends, so as not to make the only girl I love secretly sad." ”
