Stainless steel pipe types and specifications

Classification by manufacturing process

1. Welded stainless steel pipe

Welded stainless steel pipe is a pipe made by connecting stainless steel plates or strips through a welding process. According to different welding methods, welded stainless steel pipes can be divided into long welded pipes and spiral welded pipes.

2. Seamless stainless steel pipe

Seamless stainless steel pipes are pipes made by cold drawing or cold rolling processes and have high strength and corrosion resistance. It can be divided into cold drawn seamless pipe and hot rolled seamless pipe.

Classification by material

1. 304 stainless steel pipe

304 stainless steel pipe is the most common stainless steel pipe and has good corrosion resistance and mechanical properties. Suitable for general industrial, construction and decoration fields.

2. 316 stainless steel pipe

316 stainless steel pipe is superior to 304 stainless steel pipe in terms of corrosion resistance. It is suitable for chemical, marine and pharmaceutical fields and has better resistance to corrosive media.

3. 321 stainless steel pipe

321 stainless steel pipe contains stable elements and has good high temperature resistance and corrosion resistance. It is suitable for industrial and construction fields in high temperature environments.

4. 2205 stainless steel pipe

2205 stainless steel pipe is a duplex stainless steel pipe with high strength and corrosion resistance, suitable for marine engineering and chemical industry.

Classified by surface treatment

Surface treatment of stainless steel pipes can improve their appearance and corrosion resistance. According to different surface treatment methods, stainless steel pipes can be divided into bright pipes, brushed pipes and sandblasted pipes.

Stainless steel tubes also come in various shapes, such as round tubes, square tubes, rectangular tubes, and oval tubes. Depending on the shape, stainless steel pipes can meet the needs of different fields.
