Stainless steel pipe is a kind of hollow long round steel, in the industrial field is mainly used for conveying all kinds of fluid media, such as water, oil, gas and so on. According to the different media, stainless steel pipe can be divided into water pipe, oil pipe and gas pipe. In the construction field is mainly used for indoor and outdoor water supply, drainage and HVAC systems. According to the different uses, stainless steel pipes can be divided into water pipes, drainage pipes and HVAC pipes, etc.
Classification according to manufacturing process
1、Welded stainless steel pipe
Welded stainless steel pipe is a stainless steel plate or strip through the welding process to connect the pipe. According to the different welding methods, welded stainless steel pipe can be divided into long welded seam pipe and spiral welded pipe, etc.
2、Seamless stainless steel pipe
Seamless stainless steel pipe is a pipe made by cold drawing or cold rolling process, with high strength and corrosion resistance. According to the different manufacturing process, seamless stainless steel pipe can be divided into cold drawn seamless pipe and hot rolled seamless pipe.
Classification by material
304 stainless steel pipe is the most common stainless steel pipe, with good corrosion resistance and mechanical properties. It is suitable for general industry, construction and decoration.
316 stainless steel pipe is better than 304 stainless steel pipe in terms of corrosion resistance, applicable to the chemical industry, marine and pharmaceutical fields, with good resistance to corrosive media.
3、321 stainless steel pipe
321 stainless steel tube contains stabilizing elements, has good high temperature resistance and corrosion resistance, suitable for high temperature environment in the industrial and construction fields.
4、2205 stainless steel tube
2205 stainless steel tube is a duplex stainless steel tube, with high strength and corrosion resistance, suitable for marine engineering and chemical industry and other fields.
Classification according to the outer diameter and wall thickness
The outer diameter and wall thickness of stainless steel pipe have an important impact on its performance. According to the different outer diameter and wall thickness, it can be divided into large diameter pipe, medium diameter pipe and small diameter pipe.
According to the surface treatment classification
The surface treatment of stainless steel pipe can improve its appearance and corrosion resistance. According to the different surface treatment, stainless steel pipe can be divided into bright pipe, brushed pipe and sandblasted pipe.
Classification according to national standards
Different countries and regions have different standards for stainless steel pipe. According to the different national standards, stainless steel pipe can be divided into Chinese standards, American standards and European standards.
Classification by shape
Stainless steel pipe is also available in various shapes, such as round pipe, square pipe, rectangular pipe and oval pipe. According to the different shapes, stainless steel pipe can meet the needs of different fields.
