Great Power Industry: You're a private company building an aircraft carrier?

"A forty-meter-long pipe means that the steel plates you produce on your production line are also forty meters long?" The Italian man's eyes widened. "My God, how long would that production line be?"

"It's not very long, just a few kilometers. It's nothing for our Laiyang Steel Plant," Qin Chuan said, looking again at the pipes on the ground. "These 27-meter-long production lines should have been phased out long ago! Which company do you belong to? Nippon Steel? How about importing a production line from us?"

Qin Chuan flatly denied having a production line, fooled Ishino Hirotsugu, and then turned around and came to Nippon Steel to show off.

Li Jianshe, who had come along in the same car, thought to himself, "Brother Chuan, what happened to keeping a low profile?"

Shinzo Koizumi didn't respond to the conversation, but just stared at the steel pipe with a complicated expression.

At this moment, the overhead crane in the warehouse had already started moving and was unloading the truck.

As soon as the first pipe was unloaded, Shinzo Koizumi ran up to it and walked along the forty-meter-long pipe.

He strongly suspected that the pipe was made of two or even more steel plates spliced ​​together!

However, after walking around for a while, he didn't find any weld. Undeterred, he took out a magnifying glass from his pocket.

What if it was welded and then ground down?

This time he was more careful, taking a full ten minutes to examine the pipes.

The other two had already been removed to the other side of the vehicle, but before the vehicle could be backed out, Shinzo Koizumi ran to the other side to continue inspecting the other two.

He couldn't find any trace of the stitching!

Each steel pipe has only one weld seam, with a beautiful fish-scale pattern, showing exquisite craftsmanship.

But how is this possible?

Easterners now have rolling mills over five meters long, and they can even roll steel plates up to forty meters in length!

Those rolling mills built in the 1970s and 80s in the island nation are now obsolete!

"I've heard about the amazing things about your Laiyang Steel Plant for a long time, but I didn't believe it before. But now... I believe it!" Liu Xiangjun said.

“Engineer Liu, don’t speak too soon. The dimensions are good, but performance is also important. If the steel pipe can’t withstand high pressure, it will burst at any time!” Pan Qiang said, “Products from Japan are all top-quality, so there’s definitely no problem with them, but our domestically produced ones…”

"Some people have been kneeling for so long that they just can't stand up." Qin Chuan didn't even look at Pan Qiang. He came here to slap these people in the face: "Foreign goods are high-quality, but does that mean they're always problem-free? Bullshit! I'm going to defeat the high-quality ones!"

Pan Qiang's face instantly turned red: "Engineer Qin, I know that your Laiyang Steel Plant is very powerful. You have developed many types of steel and filled domestic gaps, but we can't be complacent, can we? There is a gap between us and foreign countries, and it is not shameful to admit it."

"Bullshit! Who said my products are inferior to those from abroad?" Qin Chuan looked at him and said, "Today, I'll show you, the kind of person who kowtows to foreign goods, which is stronger, our domestic products or foreign products!"

Pan Qiang clenched his fist. "Why are you acting like a mad dog, biting anyone you see? Did I say something wrong?"

“That’s right, we’ll only know once we try.” At that moment, Shinzo Koizumi came over from the other side: “I want to see just how much of a difference there is between the steel pipes produced by these Laiyang factories and ours.”

"How big of a gap is this!" Qin Chuan rolled his eyes at the other person: "Let's see how far we can go!"

There are specific methods for measuring whether a pipeline is up to standard. When the Lunku Line was laid, Korla served as a temporary storage site for the oil pipeline, and specialized testing equipment was installed there. Now, this equipment can be used to inspect the performance of the pipeline.

"Let's give it a try!" Shinzo Koizumi was absolutely resolute; he didn't think he could lose.

"Let's install valves at both ends of the steel pipe, fill it with crude oil, and then pressurize it! Let's see whose pipe collapses first!" Qin Chuan proposed a brand-new testing plan.

We won't do any of those steel strength tests, toughness tests, low-temperature tests, etc. Instead, we'll start with a pressure test that's closest to what we need in real-world applications!

"it is good!"

Shinzo Koizumi absolutely did not believe that the steel plates produced by the newly commissioned Higashiraiyo Steel Plant, which was still figuring out its production process, could be of higher quality than those produced by Nippon Steel.

They are a long-established steel giant, even more powerful than Kobe Steel. How could they be afraid of tests from Easterners?

"Isn't this a bad idea?" Liu Xiangjun frowned. "If it collapses, it could cause a lot of damage."

A gas cylinder explosion can destroy a building, and this steel pipe is many times larger than a gas cylinder! What's more, it's filled with crude oil. If this thing explodes, how will we clean up the surrounding area?

"You can just drag it outside!"

This place lacks electricity, water, and food; it lacks everything except open space.

Although our motherland has 9.6 million square kilometers of land, most of it is not suitable for growing crops, and the northwest is mostly Gobi Desert.

Zhou Yongkang gritted his teeth: "Fine, this kind of test can better reflect the actual situation, let's give it a try!"

If something goes wrong, he'll have to take the blame, but now he has to choose between two types of steel, so he's going all out!

Let's do this kind of experiment that closely resembles real-world working conditions!

Four huge valves were installed on both sides of the pipeline via flanges. The pipeline was then pulled outside and connected to the oil pipeline on this side to pump oil and pressurize it!

Everyone was busy, but Pan Qiang had a grim expression. Just now, Qin Chuan had publicly humiliated him, making him want to rush up and fight Qin Chuan.

However, with Zhou Yongkang and others present, he dared not do anything and could only keep quiet.

At this moment, he stared at the pipes outside, his feelings complicated.

I didn't say anything wrong, our domestic products just can't compare to foreign products! Why are you mocking me like that? Hmph, wait until your pipes burst, then let's see how you explain yourself!

Different pipes have different pressures.

The high-pressure pipes used in steam boilers can reach tens of megapascals, but the pipes that transport crude oil and natural gas generally only have a few megapascals of pressure. Simply put, as long as there is enough pressure, crude oil and natural gas can flow inside.

Of course, the higher the pressure, the faster the flow, and the higher the transportation efficiency.

The Kushan pipeline is the first high-pressure oil pipeline laid in China. Originally, it was planned to build a pipeline with a diameter of only a few hundred millimeters. However, on the advice of Italian experts, it was decided to grit our teeth and build a larger diameter pipeline in one go.

In fact, this is just a demonstration. If the price is too high, we might revert to the design of a 720 mm diameter pipe.

The key is whether we can use domestically produced goods, since they're half the price of foreign products! And most importantly, we don't have to spend precious foreign exchange!

"Two megapascals!"

"Four megapascals!"

"Six megapascals!"

When the pressure reached six MPa, everyone tensed up. After all, the normal operating pressure of domestic oil pipelines is four MPa, and the pressure near the booster station can be increased to six MPa, which is already the highest.

The current pipeline is designed to operate at a pressure of eight MPa, which is twice as high as the previous one!

Can domestically produced pipes withstand this kind of pressure?
