Which is the best food grade stainless steel pipe? Which is the best food grade stainless steel

There should not be many manufacturers of food-grade stainless steel pipes, and it is generally Angang Masteel to find a big brand.

Which is the best pro of food-grade stainless steel, hello, food-grade stainless steel mainly includes 430 stainless steel, 304 stainless steel and 316 stainless steel (the further back the better, stainless steel 430 stainless steel can generally prevent oxidation under natural conditions, but can not resist the oxidation of chemicals in the air, if it is not used often, it will still occur due to unnatural factors Stainless steel 304 stainless steel can resist the oxidation of chemicals, it is the material that must be used in the national pressure cooker standard, The standard Yu Ming material of stainless steel pressure cooker is more than 304, because there are not many pressure cooker production factories approved by the state, so all are 304 stainless steel used in the minimum standard Stainless steel 316 stainless steel is better, it is made of 10% nickel, stainless steel is more durable and more resistant to corrosion, this stainless steel is called 18-10 stainless steel, that is, medical stainless steel, there is no metal ion precipitation at all, very safe. I hope my answer is helpful to you, and finally I wish you good health and a happy mood again! <>

If you want to talk about stainless steel pipe brands, there are a lot of them, but if you ask about the top ten brands of stainless steel pipes, there is no judging standard, but what individuals hear every day, such as Shuangxing, Haili, Wanjia, Xingzhongcheng, Ye Jiahao stainless steel, etc.

I don't know what their criteria are for judging the top ten brands of stainless steel pipes? But as far as my personal daily chat, the ones I hear the most are: Shuangxing stainless steel, Wanjiahong stainless steel, Guangshang, Xingzhongcheng, starting point, Ye Jiahao stainless steel, etc.

There are many stainless steel brands, such as Xiyouwo, Jinhai, Brilliant, Great Wall, and Haili, which are all relatively good.

There are many stainless steel pipe factories in Foshan. If it is to evaluate the top ten brands from the output, it is somewhat unscientific. If you evaluate the top ten brands in terms of quality and brand awareness. The approximate order goes like this. Xiyouwo, Haili, Wanjia, Hongxiu, Xingzhongcheng and so on.

Shuangxing, Haili, Xiyouwo, Guangshang, etc., these brands of stainless steel are relatively reliable in quality.

Foshan is the distribution center of the stainless steel industry, manufacturers, I don't know what your criteria for judging the brand are, but personal opinions, there are very few manufacturers who can do export quality, we all know that foreign countries are very strict on quality and standards, and at present, the quality of these two exports has been well received abroad.

How to identify food-grade stainless steel

1. Material direction.

Food grade stainless steel tubing.

Generally, austenitic stainless steel is the mainstay, such as L and other materials are usually commonly used in food grade, in addition, a small part of the ferritic type is also used. Mainly the calendar bridge, these materials contain a lot of chromium and nickel.

It has strong corrosion resistance and rust resistance. Usually, the first step to identify whether stainless steel has reached food grade is to identify it from the material.

2. The surface of the round body.

Generally, the inner and outer surfaces of the stainless steel pipes that reach the food grade are polished. Since food-grade stainless steel pipes are used in food and medical contact, there are strict cleanliness requirements for the inner and outer surfaces of the tubes. We usually improve the cleanliness of the inner and outer surfaces of the tube by polishing the inside and outside.

We can do this by looking at the inside and outside surface treatments of the tubes.

It can be used as one of the bases for judging whether it meets the requirements of food grade.

The use of stainless steel pipe material is different, and it cannot be simply said which material is good. Commonly used are 430, 201, 301, 304, 321, 316, etc., as long as the quality of the material is no problem, the others are similar, the steel pipe is divided into seams and seamless, seamless is better than seams, and it is also a little more expensive, it is recommended to buy seamless, mainly depending on the working conditions.

If you choose stainless steel pipes, it depends on whether you need 201 or 304 stainless steel pipes, a large production base of stainless steel in Foshan City, there are many manufacturers, if you choose 304 stainless steel pipes, it is recommended to consider the real standard and thick Xiyouwo stainless steel, and the quality is guaranteed.

Xiyouwo stainless steel pipe:

304 stainless steel, a well-known brand in China.

Hello, I'm glad to answer for you: First of all, 304 stainless steel has good processing performance, high toughness, high density, polishing without bubbles, acid resistance, alkali resistance, etc., 304 stainless steel is widely used in industrial and home decoration industries and food and medical industries. The kitchen utensils we use in our daily life, such as pots and pans, liquid manuscripts, pans, and cups, are basically 304; Potato and 316 stainless steel corrosion resistance, atmospheric corrosion resistance and high temperature strength are better, 316 stainless steel is used in seawater equipment, chemicals, dyes, papermaking, oxalic acid, fertilizer and other production equipment, photography, food industry, coastal facilities, ropes, cd rods, bolts, nuts, if used in the food field it is a bit of a luxury, I hope my help to you.

Food grade stainless steel includes 304 stainless steel and 316 stainless steel.

304 stainless steel is a national food-grade stainless steel must be used material, and its standard material is 304 or above. Because there are not many state-approved food-grade stainless steel production plants, many factories comply with it and use 304 stainless steel. 316 stainless steel is made of 10% nickel, which is more durable and corrosion-resistant.

This stainless steel is called 18-10 stainless steel, which is also known as medical stainless steel. It is very safe to complete the precipitation of metal ions.

There is a difference between food stainless steel 304 and 316 in terms of grade, 304 stainless steel grade is 0Cr18Ni9, while 316 stainless steel is 0Cr17Ni12Mo2. The composition of food-grade stainless steel 304 and 316 is different, and the composition of CR is reduced in 316 stainless steel. And the NI composition has been improved, so that its corrosion resistance is better.

In particular, it can be used in seawater or chemical environments, but the cost of 316 stainless steel is also higher than that of 304 stainless steel.

Physical and chemical indicators:

Food-grade stainless steel refers to the part of the food machinery that comes into contact with food, which must meet certain food safety requirements. Because a lot of acids and alkalis are used in the production process of food production, and stainless steel contains chromium. Unqualified stainless steel will dissolve chromium at various price points and be toxic.

Moreover, it is required to limit the content of lead, cadmium and other alloy impurity elements.

The process is also a key factor in determining whether the food-grade stainless steel can meet the standard. To level the weld seam of stainless steel pipe fittings, the inner pipe wall needs to be finely polished and polished. Prevent the fluid from clogging in the pipe and causing secondary pollution.

Pickling passivation can improve the corrosion resistance of stainless steel products and improve the cleanliness of the inner pipe wall.

There are many large and small stainless steel pipe brands in China, and it is recommended to use stainless steel pipes with solid standards and quality assurance services!

1. TISCO stainless steel (China's famous brand, leading brand in stainless steel industry);

2. Baosteel stainless steel (China well-known trademark);

3. JISCO stainless steel (large enterprise group);

4. Mastertech stainless steel (national inspection-free product);

5. Chuangsheng stainless steel (national inspection-free product);

6. Lianzhong Stainless Steel (one of the largest stainless steel enterprises in Taiwan, China);

7. Baoxin Stainless Steel (a subsidiary of Baosteel Group);

8. Donghong stainless steel (well-known brand);

9. Nanfang NF stainless steel (well-known brand);

10. Everbright stainless steel (well-known brand).

1. The latest standard is GB "National Food Safety Standard for Metal Materials and Products for Food Contact";

2. The National Standard of the People's Republic of China - Hygienic Standard for Stainless Steel Tableware and Containers GB 9684-88 and GB9684-2011 have been repealed and replaced by GB.

In fact, the material meets the standards of various countries, so it is called a grade, and there are many stainless steel standards, that is, there are many grades, and the grades are different in various countries.

4. Only metal materials that meet the GB standard can be used for food contact; If it does not meet the GB, it cannot be used as food contact.

There are national standards, American standards, international standards, German standards and Japanese standards for food-grade stainless steel pipes, although there are a variety of standards, but they are nothing more than have quite high standards for materials and processes.

1. From the material, it can be divided into 304 304L 316 316L stainless steel, and the precipitation of heavy metals: arsenic, cadmium, lead, chromium and nickel also has certain quantitative index restrictions;

2. The process is mainly polishing and pickling passivation, in which polishing is to ensure that the inner pipe wall is smooth enough to prevent food or fluids from easily causing blockage and scaling; Pickling passivation can remove the grease on the surface of the pipe wall, improve the corrosion resistance of the stainless steel pipe, and finally clean the steel pipe to improve the cleanliness and oil prohibition of the pipe wall.
