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.

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.
