Stainless steel is more than twice as high and has enough plastic toughness for forming. The wall thickness of storage tank or pressure vessel made of duplex stainless steel is 30-50% less than that of common austenite, which is conducive to reducing the cost.

The above conditions can cause corrosion of the protective film on the surface of stainless steel.

.With the implementation of China's reform and opening up, the national economy has achieved rapid growth, and a large number of urban houses, public buildings and tourism facilities have been built, which puts forward new requirements for hot water supply and domestic water supply. In particular, people pay more and more attention to the problem of water quality, and the requirements are also increasing. Galvanized steel pipe, a common pipe, will gradually withdraw from the historical stage under the influence of relevant countries because of its corrosivity. Plastic pipe, composite pipe and copper pipe have become common pipes in the pipeline system. However, stainless steel pipe has more advantages especially the stainless steel pipe with wall thickness of only 0.6 ~ 2mm. In high-quality drinking water system, hot water system and water supply system that puts safety and sanitation first, it has the characteristics of safety, reliability, sanitation, environmental protection, economy and applicability. It has been proved by engineering practice at home and abroad that it is one of the new, energy-saving and environmental protection pipes with good comprehensive performance of water supply system. It is also a very competitive water supply pipe, which will play an incomparable role in improving water quality and people's living standards.

The shielding gas is argon with a purity of 999%. When the welding current is 50 ~ 50a, the argon flow is 8 ~ 0lmin, and when the current is 50 ~ 250A, the argon flow is 2 ~ 5lmin.

.Stainless steel pipe will not rust, but it is relatively not easy to rust. It will rust in a specific environment. It will rust if placed in seawater or acid-base environment. Even in the air it will be corroded and oxidized slowly, but it will take a long time. In general, if the stainless steel pipe is used or maintained improperly, or the environment in which the stainless steel pipe is located is too bad, the stainless steel pipe may rust. When we see rust spots on the steel surface, we can quickly confirm that it is a sign of rust. Why does stainless steel pipe rust? First of all let's understand the structure of stainless steel pipe: stainless steel pipe is a crystal solid composed of atoms similar to a piece of toys. In addition to iron, it also contains its metal components, such as chromium, nickel, titanium, etc. Chromium and nickel have anti rust function. It forms a protective film - passive film to prevent stainless steel pipe from rusting. Generally, as long as the film is not damaged, broken or contaminated by impurities, the stainless steel pipe will not rust. However, if the blunt film is damaged due to improper use or maintenance, the stainless steel pipe will rust.

Stainless steel pipe will rust? Stainless steel pipe is a food grade stainless steel pipe recognized by the state. It is not absolutely non rusting, but it is not easy to rust compared with other steel grades. Many people will think that the stainless steel pipe is not rusty, especially the stainless steel pipe has high nickel content, which is more difficult to rust. If it is rusty, they will doubt whether it is fake, whether it will be replaced by 201 stainless steel pipe, or there is a problem with the raw materials of the steel strip. In fact, these questions and judgments are one-sided views on the lack of understanding of stainless steel pipes. Stainless steel pipes may also produce rust and rust spots under certain conditions.

　　409— Cheap model (British and American), usually used as automobile exhaust pipe, is ferritic stainless steel (chromium steel).

600 Series&

Model 630 & mdash; Commonly used precipitation hardening stainless steel model, usually also called 17-4; 17%Cr,4%Ni.

Stainless steel pipe appeared in Foshan, Guangdong Province in the tenth generation of the last century. With the rapid development of science and technology in recent decades,steel strip, stainless steel pipe production is all over the country. Stainless steel pipe is more and more widely used. But in fact, most people, including many people in the industry do not know much about the classification and application of stainless steel pipes. Take stainless steel pipe for example.

Supply chain quality management.Because the family kitchen and are in the same environment for a long time, the ordinary steel pipe will rust after being used for a period of time, the service life is not long, and it will affect the safety of family drinking water! Therefore, and the corrosion resistance and tensile resistance of stainless steel pipe itself. Professional stainless steel plate, stainless steel coil, stainless steel belt, stainless steel pipe, safety, environmental protection and economy! The products are exported to foreign countries and are deeply trusted, hexagonal rod, square steel, flat steel, hexagonal angle steel,Stainless steel welded pipe, round steel, solid rod. Hexagonal rod and square steel (flat steel) are more expensive than round rod (most of the hexagonal rod specifications are imported high-quality materials). The bright surface is more expensive than black leather surface. Large diameter bars are mostly black leather rods. 303 is a unique material in bars, which belongs to easy turning (cutting) materials, It is mainly used for self cutting. In addition, 304f.303cu.316f also belong to easy cutting materials

Good corrosion resistance, suitable for a variety of media; The addition of Mo improves the corrosion resistance to reducing salts; It is resistant to marine and industrial atmospheric erosion, it has excellent grain boundary corrosion resistance; It can be used in pulp and paper machinery; Good processability and weldability.

Steel strip, thin strip, roll strip, calendering strip and other strips can be cut with a thickness of 0.03 to 0mm (Note: stainless steel calendering strips of various thickness and width can be produced according to the needs of customers)

High quality and low price.The external anti-corrosion coating of stainless steel shall be galvanized and epoxy asphalt coating or coating with higher requirements according to the soil conditions of the pipe laying ground.

The back side is not protected by argon, the backing welding wire has been developed. Recently, China has also developed the stainless steel backing welding wire (i.e. flux coated welding wire, such as tgf30tgf308tgf30tgf347, etc.) It has been applied to the actual construction and achieved good results. We have successfully applied it in the capacity expansion and reconstruction project of Urumqi Petrochemical.

The difference between duplex stainless steel plate and austenitic stainless steel plate is that the yield strength is higher than that of ordinary austenite

SPCC stainless steel belt is simply an extension of ultra-thin stainless steel plate. It is mainly a narrow and long steel plate produced to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors.

If the thickness of the steel plate is not enough, the professional stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe are strictly tested and the quality is guaranteed. The preferential activities are in progress. Welcome to consult. It is easy to bend, which will affect the production of decorative plate. If the thickness is too large and the steel plate is too heavy it will not only increase the cost of the steel plate, but also bring unnecessary difficulties to the operation. At the same time, the allowance that should be left during processing or use of stainless steel plate shall also be considered. The thickness of copper plate is not absolutely consistent, but the thickness of the same steel plate shall be as consistent as possible. Generally, for medium-sized saw plate, the thickness tolerance is 0.05-0.15mm. If the requirements are too strict, the grinding cost will also increase. Generally, it is a structural steel plate with high resistance and high degree. The greater the mechanical damage resistance, the longer the service durability but the grinding and processing cost is also relatively high.
