① The demand for building water supply pipes is large
According to the "Ninth Five-Year Plan" of the Construction industry and the Outline of the Vision Goals in 2010, it is estimated that the annual demand for pipe materials is 500,000-600000 km from 2001 to 2010, among which the demand for hot and cold water pipes in the residential construction area is 400000 km. Some people think that the development of stainless steel water pipes is of great significance to improve the grade of modern urban buildings.

All the two ends of the opening and has a hollow section, and its length and section perimeter of relatively large steel, can be called steel pipe. When the length is compared with the circumference of the section, it can be called a pipe section or pipe fittings, which belong to the category of pipe products.

Stainless steel plate open plate this name is more colloquic, the actual regular open plate and the original plate should be called single rolled steel plate and shear steel plate (or continuous rolled steel plate).
When the steel plate comes out of the steel mill, it is rolled. When the stainless steel plate is opened by the machine, the plate is called open plate. The stress level of the open plate is higher, so the dimensional stability is poor. With the different process parameters of open and flat operation, the internal stress distribution is also different, and there will be different bearing capacity in different directions of the vertical length. And this carrying capacity is difficult to measure using general strength indicators.

Stainless steel coil is not only strong corrosion resistance, but also light weight, therefore, is widely used in the automobile manufacturing industry, such as the car shell needs a large number of stainless steel coil, according to statistics, a car needs about 10-30 kg of stainless steel coil, and the United States car needs 40 kg of stainless steel coil. Now some international brands of cars are beginning to use stainless steel coil as the structural material of the car, which can not only greatly reduce the weight of the vehicle, but also greatly improve the service life of the car. In addition, stainless steel coil in buses, high-speed rail, subway and other aspects of the application is more and more extensive.

Stainless steel rolls are mostly whole when they go out of the factory, mainly for convenient transportation; In the hands of our stainless steel processing factory, in order to facilitate processing and manufacturing, we will use professional stainless steel flattening equipment to open the whole volume of stainless steel. This process is called flattening.

Although both 301 and 304 stainless steels use iron as a major component, there are several key differences in chemical composition between the two alloys, as shown in the table above, and many compounds in both steel alloys have the same end-capping values. However, grade 304 stainless steel obtained more chromium and nickel than grade 301. This tends to make grade 304 stainless steel more expensive than grade 301.

There are chloride ions in the use environment. Chloride ions are found in salt, sweat, seawater, sea breezes, and soil. Stainless steel in the presence of chloride ions in the environment, corrosion is fast, even more than ordinary mild steel. So there are requirements for the use of stainless steel environment, and the need to often wipe, remove dust, keep clean and dry. (That would give him a "misuse.") The United States has an example: an enterprise uses an oak container to contain a solution containing chloride ions. The container has been in use for nearly a hundred years. In the 1990s, it planned to replace it, but the oak material was not modern enough and stainless steel was used.

The heat transfer pipe adopts 0.5-0.8mm thin-walled pipe, which improves the overall heat transfer performance. Under the same heat transfer area, the overall heat transfer coefficient is increased by 2.121-8.408% compared with copper pipe.

Austenitic stainless steel refers to stainless steel with austenitic structure at room temperature. When the steel contains about 18% Cr, 8%~25% Ni, and 0.1% C, it has a stable austenite structure.
