As soon as he got to work in the afternoon, Geng Zhiyuan hurriedly called Wang Ping. After the phone was connected, Wang Ping's lazy voice came from the microphone, and it seemed that he had just woken up from a nap.

"Wang Gong, why is there no fixed frame for the expansion joints used in our pipelines?" Geng Zhiyuan asked truthfully.

"What?" Wang Ping was stunned for a long time before he said, "That's it, I'll take a look and call you back." ”

Putting down the phone, Geng Zhiyuan took the drawings and samples and compared them for a while, and gradually saw some doorways. The expansion joint model used in the drawing is a large tie rod expansion joint, and the two expansion joints are arranged in both directions of the 90-degree elbow respectively, and each absorbs the lateral displacement, so there is no need to set up a fixed frame.

"See?" Zhang Shulin asked with a smile when he saw that he had some understanding.

"Understand a little bit...... Geng Zhiyuan explained his understanding one by one according to the drawings, Zhang Shulin nodded and said: "Well, yes, the children can be taught." ”

He picked up the sample and said: "High-temperature pipelines need to be analyzed for stress analysis, and the thermal expansion displacement is absorbed by optimizing the pipeline direction. ”

Stress analysis and displacement are a series of new terms, which only make Geng Zhiyuan dizzy. It seems that the engineering design industry is not only about flipping through specifications and drawing drawings, but also about other hidden paths.

"If you use an axial expansion joint, you need to use a fixing frame at both ends to hold the pipe in place so that the displacement can be pushed in the direction of the expansion joint. Because the expansion joint has a blind force, the thrust of the fixed frame at both ends is very large......" Zhang Shulin tirelessly followed the teaching, and Geng Zhiyuan nodded again and again when he listened.

Zhang Shulin said: "There is a design institute that uses unconstrained axial expansion joints on a certain project, which may have been designed by young people, and they forgot to set up fixed frames at both ends of the expansion joints. As a result, when the pressure was tried, it was amazing, and a row of pipe racks was all knocked down, which became a joke in the industry. ”

"And this!?" Geng Zhiyuan was dumbfounded.

"There are a lot of strange things in the chemical industry. Zhang Shulin sighed: "We must not be false in the slightest bit about technology, otherwise once something happens, the consequences will be unimaginable." ”

"Yes!" Geng Zhiyuan sighed, but he felt a little afraid in his heart. The name of the engineer of the design institute sounds good, but the responsibility is as heavy as Mount Tai, and the money of this profession is really not easy to earn.

When he got off work in the afternoon, Wang Pingcai called back and said: "Xiao Geng, I can't say anything about the expansion joint, the world design is a big copy, and I also made it according to the previous drawings of our hospital, so I can't say why." ”

Geng Zhiyuan was dumbfounded when he heard this, this kind of thing could not be said to the people in the factory anyway, he was embarrassed: "Wang Gong, how can I explain it to the factory?"

Wang Ping said disapprovingly: "You just say that the design is based on previous successful experience, there is no problem at all, just let them build according to the drawings."

"Oh well. Wang Ping is an old comrade, Geng Zhiyuan did not dare to point out his ignorance, so he could only respond helplessly.

In Ningcheng, in the evening, Xu Guangdong and Yang Guiqin got off the bus and broke into Xu Rong's dormitory of the pressure vessel factory in anger.

"Mom and Dad, you're here. Seeing her parents, Xu Rong was not happy at all, but sighed with a sad face.

Xu Guangdong looked his daughter up and down with a gloomy face and said, "You tell the truth, whose child is it?"

Xu Rong didn't dare to face her father's fire-breathing eyes, lowered her head and whispered, "Yes...... It is promising. ”

"Zhang Youwei!" Xu Guangdong was so angry that he trembled: "This Zhang Youwei is simply a brute! He dares to spoil my daughter, I will definitely not spare him!"

He walked around the room a few times, pointed at Xu Rong and shouted, "Say, did you discuss it deliberately?"

"It's not ......" Xu Rong waved her hand and said, "I accidentally ...... it"

Xu Guangdong was so angry that he hated and said: "Go to Zhang Youwei now, Lao Tzu is going to pick his skin!

"Kid, how long have you been here? Do you have a count?" Yang Guiqin's head was much more flexible than that of the old man. With a thought in her mind, she thought of another solution, and grabbed her daughter's body and asked in a loud voice.

"The doctor said it's been more than a month. Xu Rong replied cautiously.

"More than a month...... Yang Guiqin pondered for a while, shook her head with a smile: "No! you have been pregnant for more than two months!"

"you, ...... are you?" Xu Guangdong saw his wife talking nonsense with her eyes open, and thought she was dizzy and talking nonsense.

"Old man......" A trace of slyness flashed in Yang Guiqin's eyes, and he said proudly: "If we press Rong Rong's pregnancy on the head of the kid surnamed Geng, do you think he can still agree to marry our daughter?"

"Oh......!?" Xu Guangdong frowned and thought about it, and suddenly his eyes lit up and said: "Good idea! This idea is good! Tomorrow we will go to the design institute to find their leader, if this kid dares to agree, we will make a big fuss in the design institute and make him ruined!"

Xu Rong was anxious when she heard this: "Mom and Dad, are you crazy? I am innocent with Geng Zhiyuan, and I have nothing to do with it." If you push this kind of thing on people, can they agree?"

Xu Guangdong and his wife were stunned when they heard this, and Yang Guiqin sighed: "This is troublesome, why is the Geng family kid so honest? ”

"If he doesn't recognize it, he has to admit it!" Xu Guangdong said arrogantly: "Intellectuals have always been timid and afraid of things, so we are sure that this child is his, if he dares to disown us, he will make trouble in his unit, let him lose his reputation, and see how he still has the face to stay in the design institute." ”

"Mom and Dad!" Xu Rong had no face to see Geng Zhiyuan again, let alone this kind of shameful thing, she begged bitterly: "Youwei and I really love each other, you can fulfill the two of us." ”

"Hmph!" Xu Guangdong said disdainfully: "That poor ghost! Your mother and I have lowered the bride price to 26,000, and he can't take it out." You want to marry him?

Yang Guiqin saw that her husband's words were too impulsive, and she was afraid that her daughter would not be able to stand it, so she hurriedly comforted: "Rong Rong, Xiao Geng's parents are both eating public meals, and they are in the city, and their units are better than yours, where can I find such a son-in-law? Besides, how can you be better than him than that Zhang Youwei, why are you so stupid?"

Xu Rong remembered Geng Zhiyuan's absoluteness on the phone last time, and said blankly: "Geng Zhiyuan will not agree." I know him, he's a stubborn person. Even if he doesn't work in this kind of thing, he won't give in. ”

Xu Guangdong and his wife looked at each other, and finally Xu Guangdong slapped the table and gritted his teeth and said, "XXX! Let's go to the design institute to find him tomorrow." Once it becomes us, we will pick it up, and even if it doesn't work, we won't lose anything. ”

Geng Zhiyuan didn't know anything about it, and he went to work on Tuesday to continue his research on the expansion joint. At about ten o'clock, when he was studying to the end, Han Yingjie suddenly called: "Xiao Geng, you hurry up and come back." ”

"What's wrong?Director Han, is there anything urgent?" Geng Zhiyuan heard the anxiety in his tone, and wondered.

"This ...... Your girlfriend and his parents have come to the courtyard again, and they have to see you. The hospital leader asked you to come back quickly and solve this matter. ”

Geng Zhiyuan's head grew as soon as he heard it, how did Xu Rong become a dog skin plaster, and she couldn't get out of it when she stuck it: "Director Han, I explained to you last time, we broke up a long time ago, and it doesn't matter anymore." ”

"Alas......" Han Yingjie sighed and said, "I know about this, but people are coming to ...... this time Say his daughter is pregnant, it's yours. They keep making a fuss in the hall, they have to see you, or they will find the leader, and you say what will we do if you don't come back?"

"Ah!?Xu Rong is pregnant?" Geng Zhiyuan suddenly thundered, and his mind went blank. He has been in love with Xu Rong for two years, and he has not crossed the Lei Chi step in a proper manner, the child is definitely not his, but the Xu family is so troubled, his reputation in the design institute can be regarded as completely ruined.

"Come back quickly!" Han Yingjie was caught by Yang Wenge in the morning and reprimanded him severely, and he didn't dare to stiffen it anymore, so he could only let Geng Zhiyuan come back and solve this big trouble in person.

"Okay, I'll go back right away. Putting down the phone, Geng Zhiyuan only felt that the sky was dark and his heart was in turmoil.

What can I do now?

Geng Zhiyuan sat slumped in his chair, all he could think about was what to do?

It's not difficult for him to rush back, but once the two sides meet, if Xu Rong's parents hug him on the spot and play tricks, even if the child is not his, he will not be able to argue.

At that time, it was really yellow mud that fell into the crotch of his pants, and it was not but was.

So until you think of a countermeasure, you can't go back.

It's just that if you don't go back to the hospital, you're urging it tightly, how can this be good?

Geng Zhiyuan grabbed his hair with both hands and thought hard, and when he was helpless, he suddenly had an idea, and a bright light flashed in his mind.

"By the way, why don't I do that? That should solve the problem. Geng Zhiyuan thought carefully about the possibility of operation, and only then did he pick up the phone after the idea was established.

"Zuo Gang, I'm Geng Zhiyuan, I have something to trouble you to help me......"

After making the call, he first said hello to Zhang Shulin, and when he took the shuttle bus in the afternoon, he told Wei Xiao that he had something to go back to the provincial unit.

Now that the relationship between the two is deep, Wei Xiao is already very attached to him, and he is quite reluctant: "Then when will you come back?"

"Soon, two days at most. Geng Zhiyuan took out the letter of introduction and said: "You can only take the car by yourself for the past two days." ”

Wei Xiao pouted and said, "You're not here, why am I embarrassed to take someone's bus?" ”

Wei Xiao is also a celebrity in his hometown, and it is really conspicuous when he goes out, and it is indeed not very convenient to take the factory shuttle bus alone. Fortunately, it took two days to go back and forth at most, and Geng Zhiyuan had to tell his girlfriend to live alone in the school and be more careful.

Wei Xiao saw that he had some mothers-in-law and mothers-in-law, and sneered: "If I don't meet you, won't I live in the school now?" ”

"It's cold these days, there is no heating in the dormitory, you wear more clothes, don't freeze. Geng Zhiyuan said distressedly.

"Hmm!" Wei Xiao hugged her boyfriend's arm tightly and said infatuatedly: "Don't forget me, come back early." ”

"How can it?" Geng Zhiyuan hugged her tightly and said: "Affectionate parting since ancient times, it can be even more cold to the Qingqiu Festival." Where do you wake up tonight? Don't worry, I forgot that no one will forget you!"

Wei Xiao saw her boyfriend hanging up the bookbag, happily snuggled up to him and closed her eyes.
