There are various connection methods of stainless steel pipes. The common types of pipe fittings are compression type, compaction type, live connection type, advance type, push thread type, socket and insert welding type, live connection type flange connection, welding type and the derivative series connection method combining welding and traditional connection. These connection methods, according to its principle is different, its scope of application is also different, but most of them are easy to install, firm and reliable. The sealing ring or gasket material used in the connection is mostly selected in line with the requirements of national standards, such as silicone rubber, nitrile rubber and EPM rubber, so as to avoid the user's worries.

Thin-walled stainless steel pipe, the domestic in the late 1990s began to produce, use, is today's pipe field budding family, has been widely used in building water supply and direct drinking water pipelines.
Thin-walled stainless steel pipe is durable and has been recognized by the engineering community, and the relevant parties are starting from reducing the wall thickness and reducing the price, in order to facilitate further promotion.

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.
