Xu Tuo of Wright Air Separation Group Co., Ltd. found Li Yan through Wu Miao, and after a few simple greetings, Xu Tuo asked: "Mr. Li, I can hear that your high-efficiency heat exchanger tubes have a monopoly on us." ”

Li Yan said with a smile: "This market is too professional, they are all in the same industry, how can there be any regional monopoly." ”

Xu Tuo continued to ask: "Mr. Li, you produce high-efficiency heat exchange tubes, and you must also produce high-efficiency heat exchange equipment, right?"

Li Yan didn't feel it and laughed: "If you have anything, just say it." ”

Xu Tuodao: "I have a set of equipment, and now I encounter a problem, that is, the installation space of the other party is limited, and we need to change the design, but you also know that the most important heat exchange effect is the heat exchange area, and it is difficult to achieve the final effect without enough heat exchange area." ”

Li Yan asked: "The whole set of air separation equipment is such a large set of equipment, and enough space will generally be reserved at the initial site selection, and I have not encountered this situation, even if the local space is not enough, it can be completely replaced." Big deal with the lengthened tubes. ”

Xu Tuo sighed on the other end of the phone and said: "The main thing is the increase in noise and other facilities, so the space is not enough." Didn't I come to you to find a solution?"

Li Yan said: "Oh, you send the information to me to see how difficult it is, and you are forced to find me." ”

Xu Tuo hurriedly said: "Okay, Mr. Li, you give me your email address, give me a reply as soon as possible after reading it, if necessary, I can rush over immediately, and we will talk face-to-face." ”

Seeing the information sent by Xu Tuo, the drawings and instructions in it were very clear, and Li Yan also shook his head after seeing it. The equipment was selected to pretend that the safety facilities had been sound-reducing and soundproofed, and that there had to be enough fire exits and safe distances.

As a result, the available space for the entire plant was extremely compressed, and at the other end of the site were two old air separation plants, which had to be built at a safe distance.

The information is very professionally written, and after Li Yan calculates according to the data, it is determined that the heat exchange effect can be achieved theoretically through design, but it involves the alteration of pipelines, and if the direction of these large pipelines is not changed, then it is a little dangerous.

Li Yan directly replied to his own views and suggestions, and hoped that the experts on the other side could consider it, or they could send the pipeline diagram of the whole set of equipment, and Li Yan could confirm it himself.

However, Li Yan himself also knows very well that it is almost impossible to let the pipeline drawings of the other party's hair generation equipment come over, these drawings are confidential, and the company is not allowed to leak them.

It seems that Xu Tuo is indeed in a hurry, and after receiving Li Yan's reply, he sent a message back three hours later, inviting Li Yan to communicate with their professional design engineers in person.

Li Yan would not have agreed, but the next day there was nothing urgent to do, so he agreed. Xu Tuo got Li Yan's reply, immediately made an appointment, and came to Li Yan's company with a few technicians.

This made Li Yan a little surprised, Li Yan was ready to go to Xu Tuo's company, but the other party directly said that they would meet in Li Yan's company when they went to work the next day. Knowing this, Li Yan would not hesitate to agree directly.

When Xu Tuo first arrived at the company, Xu Tuo was already waiting for Li Yan at the gate of the company.

Xu Tuo smiled at Li Yan and said, "Mr. Li, you are really a sparrow here, although you have all five organs." ”

Li Yan was busy beckoning Xu Tuo and the three engineers together to the largest office, and Li Yan did not set up a special reception room, so he could only temporarily requisition this slightly larger office.

After a brief introduction, I will get straight to the point, all of them are engaged in technology, and when discussing technology, I will immediately devote myself to it, and there is no excessive other consideration.

At this time, Xu Tuo became redundant, Li Yan and the three engineers had four computers, and Li Yan also specially took the three largest display screens in the company and connected them.

The three engineers were surprised that Li Yan was very familiar with air separation equipment, and he was even more proficient in individual equipment. So he asked, "Mr. Li, have you designed air separation equipment before?"

Li Yan said with a smile: "Except for the distillation tower in the air separation tower and the intermediate refrigeration condenser, almost all of them have been done. ”

"No wonder. ”

"Mr. Li, it is difficult to move all the pipes you mentioned, and the position you see here is not enough, and you have to leave an insulation layer and so on. ”

After thinking for a while, Li Yan said: "You have thought about changing the entire refrigeration direction, adjusting the position of the air cooler, and adjusting the position of the rows of star-shaped heat exchange tubes to the outside, so that the space will come out." ”

"Mr. Li, just this kind of adjustment, the workload is a bit large. ”

"Has the foundation of the site started to be built?"

Xu Tuo immediately replied when he heard it: "Not yet, we are waiting for the implementation of our final plan, and then the foundation drawings will be determined before the construction will start." The other party was in a hurry. ”

Li Yan said: "It's easy to do without starting construction, first make the rough design, the foundation can be determined, and then when they build the foundation, they have enough time to complete all these design changes." ”

"It's just that after the foundation changes, it can't be changed, and the heat exchange effect is not up to standard, but there is no room at all. An engineer asked directly.

Li Yan said directly: "I will provide you with all the parameters as soon as possible, and then you can simulate, and I will add margins in the design, so you can rest assured." ”

"We've calculated many times that the heat exchange area can't be reached at all, even if you change it in your way, but there is still not enough space. We have made a limit estimate, that is, to move all the equipment that can be moved, to make room for the heat exchange equipment, but it is not enough. ”

Li Yan said with a smile: "In this way, I will show you my product parameters, and after reading it, you will calculate it in your way, and if there is any problem in the end, we will study it." ”

For a day, the four of them, including Xu Tuo, ate lunch in this office. There is almost no rest in the middle, even when I go to the bathroom, I trot to the bathroom.

Xu Tuo is a little tired, but those who are engaged in technology, once they devote themselves to technology, time and environment do not exist, and in the eyes of technical people, there is only technology.

When the cuckoo came over to announce dinner, four people lay on a desk with their heads huddled together, gesturing at a piece of paper full of lines.

"Brother, it's time for dinner, everyone has finished eating, and there are only a few of you left who haven't eaten, and the master of the family has to clean up. ”

Li Yan said without raising his head: "Girl, you just bring in the food for the four of us, and we will eat here." ”

Du Juan said: "Have a meal, just take a break, don't be so tense all the time, it's not efficient." ”

After listening to this, Li Yan looked at the paper in front of him again, then threw the pen in his hand on the table and said, "Okay, listen to you, eat." After eating, you can also take a look at my products here, which contains almost all the high-efficiency heat exchanger tubes, and of course there are no condensation plates in the air separation tower. It's so easy to make, you're not surprised by that. ”

Two days later, Li Yan provided all the heat exchanger parameters, and Xu Tuo called Li Yan on the afternoon of the third day and asked: "Mr. Li, I will give you some of these heat exchange equipment to make, can you eat it?"

Li Yan said with a smile: "Mr. Xu, don't say it's a part, just give it to me, and I can not delay your construction progress, because I already know your entire project very well, the interval between the equipment entering the site, if I make full use of it, I can not only complete the equipment production on time, but also have spare time." ”

Xu Tuo asked puzzledly: "Mr. Li, your site is so big, even if all the equipment is stacked in your site, you can't put it down." ”

Li Yan said with a smile: "Mr. Xu, you are the way of thinking of a large enterprise, I just need to find a warehouse, and the equipment is not produced at the same time, and the more important thing is scheduling, as long as the scheduling is good, these equipment are not much." Duration is not an issue. ”

Xu Tuo was a little pleased, and immediately said: "Mr. Li, we only provide parameters, and the design of the equipment is fully undertaken by your company, what do you think?"

Li Yan complained a little bitterly, because now his own company designs, isn't it his own design? Moreover, so many equipment are designed according to special circumstances, and they are all non-standard equipment, and the workload of this design is very large. And not only is the workload of design very large, but also the formulation of production drawings and processes later, and the workload of these is even greater.

Feeling Li Yan's hesitation on the other end of the phone, Xu Tuo added: "Mr. Li, I can get you the best way to pay this time, 5311, what do you think?5311, this is my greatest authority, and when the time comes, I can also give you the middle '3' in advance, to ensure that Mr. Li has no financial pressure." ”

Li Yan took a breath and said, "This payment method is okay, but we haven't agreed on a contract yet." The final equipment price and so on are not discussed. ”

Xu Tuo smiled: "As long as Mr. Li is sure that he can eat them all, I will make a special trip to talk to you about the rest of the things, as long as you pass this for me, I Xu Tuo will definitely remember it in the future." ”

Li Yan said: "Mr. Xu, we are also old acquaintances, we will talk about it when you are free." ”

"How's tomorrow?"

Li Yan smiled and said, "Mr. Xu, are you in such a hurry?

"Okay, I'll be there on time. ”

What Li Yan didn't know was that Xu Tuo had found several manufacturers who had been supplying equipment to their company in the past few days, first of all, the problem of the construction period, because the other party needed Wright Air Separation Group Co., Ltd. to provide all the design and manufacturing drawings before starting production, and almost all of the heat exchange equipment was made of high-efficiency heat exchange tubes, and some manufacturers had not yet used them, and all the quotations were a bit outrageous.
