There is a wide range of stainless steel pipe type. Because the technical requirements and applications are different, the production method processes of stainless steel pipes are different as well. At present, there are five methods to deal with the stainless steel pipe type. In the rest of this passage, we will explain them respectively. The first method to classify the stainless steel pipes is according to the production mode.

Stainless steel pipes can be divided into two main types: seamless stainless steel pipe and welded stainless steel pipe. And the seamless stainless steel pipe can be divided again in to four smaller types: hot-rolled pipe, hot-rolled pipe, cold drawn pipe and extruded tube. And the welded stainless steel pipe can be also divided into two smaller types: longitudinal welded pipe and helical weld pipe. The second method to deal with the stainless steel pipe type is to classify the stainless steel pipes depending on the sectional form.

According to the sectional form, the stainless steel can be divided into circular pipe and special section pipe. It is easy to understand the meaning of circular pipe, but not easy to make sense with the concept of special section pipe. Just as its name implies, special section pipe means rectangular pipe, diamond shape pipe, oval pipe, six-point pipe, eight-point pipe and other asymmetric pipes. The third method to deal with the stainless steel pipe type is to classify the stainless steel pipes depending on texture. According to different texture, stainless steel pipes can be divided into: common carbon steel pipe, high quality carbon steel pipe, alloy structure pipe, alloy-steel pipe, and so on.

The forth method to deal with the stainless steel pipe type is to classify the stainless steel pipes according to the shape of pipe end. In this way, stainless steel pipes can be divided into: smooth pipe and deformed steel pipe. Deformed steel pipe can be further divided into common deformed steel pipe and special deformed steel pipe. The former is usually used to convey water or coal gas, and the later is commonly used in geological drilling. The fifth method to deal with the stainless steel pipe type is to classify the stainless steel pipes according to the usage. Classified by use, the stainless steel pipes can be divided into oil well pipe, pipeline pipe, boiler pipe, mechanical structure pipe, chemical engineering pipe, and so on.

Many people might make a mistake that they do not regard black steel pipe as a kind of stainless steel pipe. In fact, black steel pipe is a kind of steel pipe whose surface is not processed with polishing，wiredrawing，oil paint and so on. Although they are not shiny on the surface, but they are still belonged to the stainless steel pipe type.
