Indeed, pipes belong to the simplest category of industrial products, but they are not plastic bags, they are pipelines, power pipelines, main steam pipelines, high-temperature and high-pressure pipelines, with specifications, processes and quality requirements, and they will explode if there is a problem.

"Director Zhang, we haven't ...... yet" Wu Qiangmu was the first to say after a long time.

Zhang Yifu immediately interrupted: "Production qualifications? Hengdian does not have a second repair factory, with a second repair factory, I know what you are thinking, rest assured, no one will jump out and entangle this matter." ”

Without waiting for Wu Qiang to reply, Zhang Yifu looked at Xiang Xiaofei: "What's your problem?"

"Do you want to formally sign a purchase contract?"

"I can't sign it, because no one can guarantee that Hengdian will be able to produce this thing. Zhang Yifu had already thought of the latter thing, "If Xinming really does it, this batch of pipelines will be pressed, pressed, and will be used soon." ”

“…… We can't be ...... with a loan."

"Don't be afraid, P92 is the main pipeline in the future, and there are not many manufacturers that can produce this kind of pipeline now, which is a very practical and cost-effective investment. Zhang Yifu then turned to Lao Chang, "The teacher wants to ask about the process technology, right?"

"Not bad. Chang Siping nodded, "This type of pipeline is a European technology, although it has been introduced in China + ♀ now, but for the inexperienced production team, it is difficult to complete such a heavy task as scheduled."

"It doesn't have to be as scheduled, before the end of the month, you can pass the guò inspection. Zhang Yifu nodded, "As long as the sample has been inspected, the industry certification is P92 of qualified quality." ”

"Specific Experimental Research ......"

"I got the finished product guidance standard through private channels. Zhang Yifu then took out a handwritten draft from his briefcase, "It's rough, but it's enough for people in the industry to master this." ”

This time, Zhang Yifu didn't go around in circles, and he didn't have time to go around in circles, he was simple and rude, and he made it out.

The three people on the opposite side looked at each other blankly. In the end, they all showed calm expressions.

"Give it a try. Chang Siping rubbed the forehead lines on his head, "Although it's not complicated, it's too time-sensitive." ”

"If you lose money, you have to think to make up for it. Xiang Xiaofei was obviously thinking about practical interests.

"Then I'll contact the squad leader and the master now?" Wu Qiang was already ready to work.

"Don't worry, I'll make it clear first. Zhang Yifu temporarily stopped Wu Qiang and counted them. "First, as I just said, P92 has a good use effect, the technical threshold is not high, it is the mainstream in the future, and there is absolutely no harm in mastering it; At this time, Hengdian jumped out to save the scene, and the top leaders of the energy-saving project will remember Hengdian's good strokes, which has an important impact on the interests of Hengdian when it is promoted nationwide in the future; third, I have contacted the power system publicity publications to start advocating energy-saving projects, I am unlucky to drop the chain, Xinming and Zhuoguan don't think about it, and finally if it is made up, I have a way to make the system publications blow up. Hengdian just took advantage of this to make a name for itself, laying the foundation for further microcomputer protection and automation. Of course. Hengdian has to pay a certain fee to the publicity unit, which is counted as advertising expenses. ”

The three of them were stunned for a long time, if it is really as Zhang Yifu said, in such a predicament, Hengdian can exert great power, these benefits are really not too much, it is the so-called wealth and danger to seek!

"The most critical thing is. Zhang Yifu did not forget to click on the table and prompted. "This thing was done by Hengdian stuffy, it didn't work, and it didn't hurt, since there is such a good thing, why don't you work hard?"

After Zhang Yifu's brainwashing. P92 pipeline production from a terrible task, against the sky, into a great opportunity, a dose of aphrodisiac to make people excited.

"Wait, what's wrong...... Xiang Xiaofei frowned and thought about it, this was completely opposite to his first reaction, "That's right! I will lose money! Steel is not cabbage!"

"See the first one, I ate first. Zhang Yifu buried his head in eating, "Lao Chang, Wu Qiang, do you have any other opinions? Put it forward early, and if you don't accept it psychologically, don't accept it." ”

"This ......" Wu Qiang glanced at Chang Siping, and then said, "I have been engaged in steel pipe manufacturing for many years, can you first talk about P92 conceptually, and briefly talk about the materials and processes, so that I can have an understanding of the difficulty of production." ”

Zhang Yifu lightly clicked on the handwritten draft on the table, pushed it over, seized the time, and bowed his head to eat it.

Lao Chang and Wu Qiang gathered together to study this thing, which is relatively new compared to domestic products.

P/T92, an abbreviation of steel, is a Europeans on the basis of P/T91 optimization and development of a more excellent material, alloy steel, than most ferroalloys have more powerful high-temperature strength and creep properties, in weight also has advantages, fatigue resistance, heat conduction, expansion coefficient has an extremely excellent table.

These advantages are the most needed in the working environment of high-pressure and high-temperature power plants, and the material properties of P/T92 are also fully competent for the pipeline needs of power plants, and more interesting is that P/T92 also meets the parameter requirements of supercritical units, and will become the main force in power plant pipelines for a long time in the future, especially in large-unit power plants and supercritical unit power plants.

Subdivided, it is divided into T92 and P92, the former is used for superheaters, reheaters, the structure is smaller, the latter is used in headers and steam pipelines, due to the difference in technology, the organization of P92 will be larger than T92, and the main steam pipeline to be replaced now is the P92 that has been discussed.

Zhang Yifu has not paid attention to this thing, just because the threshold of this thing is not high, after a period of time, the industry will appear guiding standards, public manufacturing details, compared to so many equipment, this thing belongs to a hard-working and hard-working product, you do it you will not starve to death, but don't rely on it to be among the first-class.

But now the situation is different, Zhang Yifu has to take out this thing, the only thing he is afraid of is that the second repair factory is not up to par in manufacturing hardware, and there is no such production conditions. However, in my impression, the director of the mahjong factory only entered a batch of new equipment for the production of steel pipes in the first two years, which was clean and shiny, and was hardly used.

Chang Siping and Wu Qiang watched intently, and let them discuss for a long time in the first few lines.

【……】

In fact, Zhang Yifu can't understand this series of things at all, the industrial standard is infinitely powerful, which is equivalent to telling you a 20,000-word description of requirements with a line of letters. It's like a certain general bureau wants to ban a movie, and it is usually said at the beginning that according to the requirements of "XX Order", "Document No. XXX Jiàn", and "National XXX Standards", we decided not to let "The Legend of Wu Meiniang" be broadcast.

If you have to study why, you have to read "The first xxx good article jiàn", which will tell you that your career line can only be exposed for a few centimeters at most. Of course, now there is no need for a reason for what the General Administration wants to prohibit, and I don't bother to list the reasons, what about literature and art, playing rigorous will only pit yourself in!

But in the industry, must be rigorous, how rigorous is not too much, this national standard, strict provisions of materials, technology and quality, insiders glance at these standards, probably can know whether their factory has the conditions to produce.

But no matter how expert he is, it is impossible to make these terrible things familiar to him, and he often discussed with Wu Qiang for more than five minutes before continuing to look down.

Material requirements, welding wire, electrode model specifications, argon purity requirements, welding process guidance, temperature, voltage and current requirements, until the finished product quality standards, these details are very smooth, much easier to understand than those standards, just like the master is teaching the apprentice, knowing that the apprentice knows the big concept, so only mention the key points, do not repeat.

Twenty minutes, Lao Chang and Wu Qiang probably finished reading, this time the feeling can be completely different from the last time Zhang Yifu proposed the economizer welding process, that time is a little bit of a lead, put forward an angle, a method, there are theoretical people to put it forward, and it is reasonable, this time, you must be a master who is proficient in a qiē to put it forward.

Zhang Yifu explained this from the beginning that this thing was obtained through Guò's personal channels, and Lao Chang and Wu Qiang were convinced of this, and they must have obtained it from some factory, which is really critical information at the level of commercial espionage.

It's a bit morally uninteresting, but it's not something that no one has patented and can't patent, so it's not an ethical thing.

After this little effort, Zhang Yifu is also finished eating.

"How?" he asked, wiping his mouth.

"In general...... It should be produced conditionally, after all, the second repair plant is in pipeline production, and it also has considerable experience in this area. Wu Qiang raised his glasses, and a large amount of concentrated thinking had made his brain ooze oil, "I have to check the standard again to confirm it." ”

"What about the details?" Zhang Yifu turned to look at Chang Siping.

Lao Chang Zhengse nodded and said: "It's very clear, it's not too difficult, the main thing is the choice between manual arc welding and submerged arc welding, and then there is the control of heat treatment, if the hardware conditions and base material are in place, you can try." ”

"Is steel easy to do?" Zhang Yifu asked Wu Qiang again.

"Not sure, maybe imported. ”

"Well...... Zhang Yifu pondered for a moment, "the target is Zhuoguan Factory, I'll contact you." ”

According to the contract with Zhuoxian Steel Pipe Factory, they were originally scheduled to deliver the goods within two weeks, and the temporary order, the oil side is unlikely to use this specification of steel, so this batch of base metals should have been in place, with an appropriate relaxation of the penalty for breach of contract to make a transaction, I believe they will agree to change hands.

Wait, is this an abuse of power......

Maybe forget it, but it's not important, it's okay to make it public yourself, Hengdian regularly spends money to buy it, and every qiē is for work. (To be continued......) R752
