It takes about an hour for the pipe to go from the inlet to the outlet.

In between, Li Wei carefully checked every link. As long as there were no major problems, he would not say anything.

Because if it is a minor problem, the minor problem that Li Wei thinks may not be a minor problem.

Because Li Wei has not personally operated it, it is not clear whether these minor problems are minor problems.

After all, it’s good not to say it, it’s too wrong to say it.

As long as the product is qualified, this assembly line will be qualified in Li Wei's opinion.

"Come out soon..."

Li Wei stood beside him and asked Wu Qiming.

"We tested it yesterday. If you have a speed of 300, the total time from in-out is 1 hour and 07 minutes.

It will be out in about three or four minutes."

Wu Qiming was very nervous now and stared at the outlet without blinking.

Sometimes I frowned, sometimes pinched my left hand with my right hand, sometimes pinched my right hand with my left hand, and sometimes clamped my fists with both hands, showing a very irritable look.

Can understand.

After all, he has paid so much and the boss trusts him so much, so he has to leave it to him to take care of it. If the product is not up to standard, he really cannot explain it to himself or the boss.

Anyway, Li Wei thinks that his product is fine. If there is any problem, try to find the reason from the assembly line as much as possible.

This is not only Li Wei's confidence, but also a necessary skill as a supplier.

If there is really a problem with the product, then your own testing will not be possible.

During the reaction process, powder coatings, all aspects of the conditions will have an impact. They cannot be attributed to the coating itself. They are an impact of multiple aspects.

But as a boss and as a supplier, Li Wei must make his products have no problems.

Otherwise, how can we cooperate in the future?

Even you admit that there is something wrong with the product, how can others trust your product?

I saw a piece of red tube slowly moving out from the outlet.

Everyone was nervous, including Li Wei, of course.

If this product is successful and has very good results, it can be promoted in depth in the pipeline industry.

"Don't touch!"

I saw a worker not far from the exit and wanted to touch it with my hands.

Li Wei immediately stopped him, what are you kidding? If you encounter this, your hand will definitely be a bubble.

The newly released pipe has a very thick pipe, so it dissipates heat slowly, and the temperature at the outlet is at least 160 to 70 degrees.

This temperature is more than 70 degrees at the beginning. Think about it, can you touch the boiling water in the boiling water?

“You workers are not trained enough!”

Li Wei’s rare criticism and the emergencies just now made Wu Qiming look ugly.

He had actually emphasized it, but the workers seemed to not care.

Those who have never suffered losses will never know what kind of regret they will regret after suffering losses.

So sometimes the company's training is not just an emphasis. It is necessary to let them experience it personally. It is necessary to tell them what can be done and what cannot be done at the scheduled location.

Moreover, some people who can cause personal injury must have obvious warning signs.

For example, high temperature, fire prevention, mechanical injuries, etc.

A little away from the discharge port, you can still feel the vigorous erupting heat.

So the electric fan was blowing, and it was nearly 30 meters away from the discharge port to the discharge port.

This distance is to allow the fan to cool the pipes.

In addition, heat-insulated gloves must be worn when unloading.

Of course, the load-bearing machinery is still the one that carries weight. After all, even if these pipes reach the discharge port, the temperature is still relatively high, which may be as high as fifty or sixty degrees Celsius.

Just take it off manually by hand and then use a robotic arm to carry the weight.

"To let it cool completely, the best situation is to test it again at this time tomorrow.

But we can conduct preliminary testing. If the preliminary testing is passed, there should be basically no big problem."

"Do you have to wait until tomorrow?"

Wu Qiming was a little confused. Will the test be detected when the pipe has completely cooled down?

"The reaction of powder coatings is not only about the inside of the powder coating, it also involves some electronic exchange between the coating and the pipe.

Complete cooling may be enough for one hour, but its performance has not yet reached a stable level.

The best performance is the moment when it cools to room temperature.

Then its performance will change slightly over time, so you have to detect performance one day after complete cooling.”

"That's it... I remember when I was in other pipeline manufacturers, they tested it completely when they cooled down that day."

This is what Wu Qiming is very puzzled. He has been in that factory for a few years and thinks he is still familiar with the process.

"That's because they have long been familiar with the performance of the product.

This is the first time our product has been tested, and there is no comparison.

Therefore, in order for both parties to cooperate more friendlyly in the future, your performance inspection must be carried out one day after complete cooling.

This way, the performance of this paint can be truly reflected.

And it can reflect whether your overall assembly line is qualified.

But I just said that we can now conduct preliminary testing.

In fact, I am confident that the results of the preliminary test will not be too far from the results of the test tomorrow.

But in order to be more convincing, I suggest you do a test tomorrow.”

It turned out to be like this, Wu Qiming nodded, and then gave Li Wei a thumbs up in his heart.

This is for them to consider, so Wu Qiming is still very grateful.

The pipes came out one by one. This time, 100 pipes were tested.

There are three specifications in total, including 32 inner diameter, 50 inner diameter, and 70 inner diameter.

Of course, there are also differences in the thickness of the pipe wall, so three are extracted for each specification and then performance testing is performed.

The most important thing is definitely adhesion, then corrosion resistance, and then anti-aging.

"50 tubes, average thickness of 142 microns"

"32 tubes, average thickness of 137 microns"

"70 tubes, average thickness of 144 microns"

After He Qian reported the number, Wu Qiming nodded.

"This is perfectly qualified, and it's even a little beyond my expectations."

"I think you can also reduce the preheating temperature a little, with an average thickness of 140 microns, which is a burden on your cost."

"No, the price of our pipeline is not low, so the quality must be done better."

Well, actually Li Wei really wants to say that for your natural gas pipeline, the thickness of the coating is no difference between an average of 90 microns and an average of 140 microns.

Since he was willing to use more paint, how could Li Wei refuse?

If you use 50% of the paint, wouldn’t Li Wei make 50% more money?

Just like those soy sauce manufacturers, the reason why the soy sauce bottles are getting bigger and bigger is that you can eat more soy sauce.

Then test the adhesion and use a hundred grid knife. The final detection result is zero grid, and the adhesion is completely qualified.

Li Wei even suggested using a kilogram of iron hammer to detect the performance of the coating.

I was just talking casually, but who knew that I actually found a hammer in front of me.

And he gradually increased his strength to hammer the coating, but even Li Wei was actually quite surprised.

"You know that when our pipes are installed, there will definitely be various irregular positions, so we must use a hammer.

I just tried the strength, and with the greatest strength, I can only remove a little skin, which means that your paint is excellent.

Mr. Li, happy cooperation!!”

Li Wei stretched out his hand with some smugness. He actually didn't know that his product was so excellent.

So he turned his head to He Qian, hoping that he could give his own explanation after he went back.

“Happy cooperation!!”
Chapter completed!
