Stainless steel pipe is a kind of strip steel. Generally, the stainless steel pipe application shows in conveying fluid, such as oil, natural gas, water, coal gas, steam, etc. In addition, under the same strength of bending and torsion, the weight of stainless steel pipe is lighter than other materials. Therefore, the stainless steel pipe application also shows in engineering structures and the manufacture of machinery parts. It is also commonly used in the production of various kinds of conventional weapons, barrel, shells, and so on. As the increasing development of stainless steel pipe, it will definitely be more widely used in future.

The prospect of stainless steel pipe application is mainly embodied in three aspects: building materials, water supply system and light gauge stainless pipes. Because the stainless steel has the ideal performance that building materials requires, it is considered as the unique metal material. And its uniqueness is still developing. Due to the increasing production efficiency and quality improvement, stainless steel becomes the most cost-effective materials that architects trend to choose. This is the first aspect of the prospects of stainless steel pipe application. With the implementation of China's reform and opening up policy, the national economy obtains a rapid growth and the urban housing, public buildings and tourist facilities are under building in great quantities. People put forward new requirements of the hot water supply and water supply, especially, the water quality problems.

In the past, black steel pipe is commonly used in water supply system. But the black steel pipe has many shortcomings, such as poor performance in corrosion resistance. Under the influence of national policy, black steel pipe will gradually become relics, and plastic pipe, compound pipe and copper pipe are going to be commonly used pipes. But in many cases, the stainless steel pipes take more advantages over others. This is the second aspect of the prospects of stainless steel pipe application. The third aspect as well as the last aspect we are going to talk about of the prospect of stainless steel pipe application is light gauge stainless pipe. The engineering practices both at home and abroad show that the light gauge stainless pipe is one of the most promising materials used in water supply which has best combination property and it is new, energy saving and environment friendly.
