Chapter 47 Headache Valve Company

Huazheng Valve Group has nearly 20 years of rich experience in valve production and manufacturing. It has 7 wholly-owned and holding subsidiaries, including 3 manufacturing entity companies and 2 trading companies. It is a national high-tech enterprise. It was established in 2007 The output value is about 500 million yuan.

Headquartered in H City, Jiangnan Province, it has a manufacturing plant, which is mainly responsible for the processing of gate and globe valves, including welding.

Recently, a batch of products sold out was returned by a foreign Aman Petroleum Company PDO customer and fined 100,000 US dollars.

At this time, the general manager of the company, the technical director of the group, the quality manager, the welding supervisor, the welding workshop supervisor, two deputy managers of the technical department and the purchasing manager gathered in the conference room on the second floor of the office building.

The atmosphere in the meeting room was oppressive, and even Mr. Chen, the technical director who usually liked to laugh in meetings, was full of sadness at this moment. He was bald in his forties.

Mr. Wang, the general manager, tapped his finger on the table: "Our company got Aman's gate valves in the first half of the year, and there were actually five gate valves leaking. From the photos sent by the customer, it can be seen that the sealing surface of the welds is cracked.

Moreover, on-site spectroscopic detection of alloy elements found that the iron element on the sealing surface seriously exceeded the standard, reaching 13.5%!

And how much is the standard requirement?

Less than 5%!

Mr. Zhang, you are in charge of the quality, so let me tell you what is the reason. "

"Mr. Wang, the valves we sent out all leaked after pressure testing in the workshop, which means that there was no problem in the original inspection.

The sealing surface of the welding seam is cracked, and the base material of the gate plate is chrome-molybdenum steel F11, and the material itself has a relatively high tendency to crack. Mr. Wu should be more aware of this problem. Zhang Gong organized his speech, and without hesitation, blamed Wu Ming, the welding engineer of the technical department.

"grass"

"Uncle Ni!"

Wu Ming scolded Mr. Zhang secretly, and the leader of the quality department knew how to blame him.

Seeing that everyone in the meeting room was looking at him, especially his leader, Mr. Chen, he knew that he would be asked these questions before the meeting, and he had already figured out how to answer them.

"Leaders, the welding process is no problem. It has been verified for many years. This chrome-molybdenum steel F11 has a high carbon equivalent, and it is indeed prone to cold cracks in welding. Therefore, it needs to be preheated to about 250 degrees before welding, and asbestos is used to keep it warm after welding. Cool slowly, and then carry out post-welding stress relief heat treatment at 700 degrees.

If the surfacing layer is too thick and the post-weld stress relief heat treatment is not done well, the welding internal stress will still be released during use, and it is normal for cracks to appear.

As for the iron element exceeding the standard, it depends on whether the workers follow the welding process during manufacturing. "

Mr. Wu did not directly point out that it was a problem in the workshop, but implied that the welder did not operate according to the welding process, which was prepared by him, so it cannot be said to be a problem with the process anyway.

In fact, he himself knew that this job was not easy to do.

If the problem of less than 5% iron can be solved, foreign orders will not be filled. After all, the products made in Huaguo are much cheaper than foreign ones.

However, at present, various valve manufacturers have not been able to solve this problem, including the leading valve factory Kawei.

Hao Jian, the supervisor of the welding workshop, quickly explained: "The workshop has done preheating and post-weld heat treatment. The cracks may be caused by the base material. These castings often have sand holes and shrinkage cavities, which are prone to cracks."

Song Huan, the manager in charge of casting procurement, gave Hao Jian a blank look, and despised his statement: "Hehe, Director Hao, you are going too far. There is a problem with the casting. You must have discovered it when you welded it. Why didn't you contact the purchasing department at that time?" feedback.

If there is a problem, we can return the product to the foundry. Why do customers say it is a problem with the casting when they find the problem. "

The general manager hurriedly knocked on the table: "Okay, now is not the time to shirk any department's responsibility, this incident caused a very bad impression on the major customers, and the company was fined.

Mr. Chen, your technical department should see if there is a better way to completely solve the problem of surfacing STL. Last year, hundreds of thousands of them were found, all of which were excessive alloying elements and cracks. "

The general manager is the boss' brother-in-law, who owns 5% of the company's shares and has a great say.

Most of the private enterprises in Jiangnan Province are family enterprises.

There may be quarrels within the family, but externally they are consistent. When doing business, only if you know how to stick together can you grow bigger, so you will not do things that damage the company.

Otherwise, the company has been established for so many years, and the company would not be able to grow so big, and everyone would have parted ways long ago.

Mr. Chen smiled wryly: "Mr. Wang, this problem has always existed, including the leading valve factory, which has not been solved. Mr. Wu, do you think there is any good solution?"

Wu Ming replied: "The welding consumables, castings and equipment of foreigners are better than ours, and they can only meet their requirements under strict technological conditions.

Imported STL6 welding consumables cost at least 500 yuan per kilogram, which is too expensive and not easy to buy. "

No need to explain too much, even if it can be done, the cost will rise sharply, which is a loss-making business.

They were in a meeting, when the door was suddenly pushed open, and a handsome young man walked in, wearing a light blue suit, with well-combed hair and a confident smile on his face.

This person is exactly Mu Yang.

Huazheng Valve Group is Mu Yang's old employer in his previous life, and their headquarters is only a 20-minute drive away from Xinghai Company.

After the successful debugging yesterday, Mu Yang soldered a few more samples, and came here this morning, intending to talk to the general manager about OEM cooperation.

When he drove into the gate, he was stopped by the guard, but he knew the guard's name, handed him a cigarette, and said that he had made an appointment with Mr. Wang.

The doorman has been working in the company, even in 2022, he is still doing it, so Mu Yang still remembered him when he saw his younger face.

The old guard had never seen him before, but he recognized that Mu Yang's car was a luxury car. He had good eyesight, and he was probably a big customer. He smiled and asked him to park in the customer's parking space. Foreign vehicles were not allowed to enter the production area.

The company only needs to register for outsiders to enter, but if they want to go out, especially by car, they must strictly check whether they are carrying company items.

Mu Yang came outside Mr. Wang's office and saw no one else through the glass window. He asked the employee next door to his office and said Mr. Wang was in a meeting.

After inquiring, he found out that Mr. Wang was holding a quality meeting to discuss the quality of surfacing STL6.

Mu Yang thanked this young man who had just joined the job and came outside the meeting room, their meeting had just ended.

Mu Yang knocked on the half-covered door, and after hearing "Come in", he pushed the door in. He saw Mr. Wang and other familiar people, and at the same time glanced at the meeting content on the projection cloth.

Huh?

It is really discussing the quality of surfacing STL6.

"Mr. Wang, hello, have you solved the quality problem of surfacing STL6? If not, maybe I can help you solve it." Mu Yang didn't finish his words, even though he was very familiar with the common problems of surfacing STL6.
